14 CFR Part 39

[Docket No. FAA-2010-0220; Directorate Identifier 2008-NM-166-AD; 
Amendment 39-16342; AD 2010-13-11]

Airworthiness Directives; Fokker Services B.V. Model F.28 Mark 
0070 and 0100 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD results from mandatory continuing 
airworthiness information (MCAI) originated by an aviation authority of 
another country to identify and correct an unsafe condition on an 
aviation product. The MCAI describes the unsafe condition as:

    Due to their position on the aeroplane, fuel fire shut-off valve 
actuators P/N [part number] 9409122 are susceptible to freezing, 
which has an adverse effect on the operation of the valve. Also, due 
to various causes, the failure rate of [fuel fire shut-off valve] 
actuator P/N 9409122 is higher than expected. Failure or freezing of 
the actuator may prevent the flight crew to close the fuel fire 
shut-off valve in case of an engine fire.
* * * * *
    Due to their position on the aeroplane, fuel crossfeed valve 
actuators P/N 9409122 are susceptible to freezing, which has an 
adverse effect on the operation of the valve. This condition, if not 
corrected, may generate fuel asymmetry alerts when a valve remains 
in the open position after being selected closed. It may also 
prevent the flight crew from correcting a fuel asymmetry when a 
valve remains in the closed position after being selected open. One 
event was reported where, due to such problems, the flight crew shut 
down an engine in-flight and diverted the aircraft.
* * * * *
* * * [D]ue to their position on the aircraft, ice may form on 
actuators P/N 9409122 installed on fuel crossfeed valves and fuel 
fire shut-off valves. Tests revealed that the ice can prevent the 
actuator and thus the valve from operating in flight (frozen stuck). 
* * *
* * * * *
    We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective July 28, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of July 28, 
2010.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on March 9, 2010 (75 FR 
10696). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    In-service experience revealed that, due to their position on 
the aircraft, ice may form on actuators P/N 9409122 installed on 
fuel crossfeed valves and fuel fire shut-off valves. Tests revealed 
that the ice can prevent the actuator and thus the valve from 
operating in flight (frozen stuck). A new actuator is being 
developed by Fokker Services. However, an airworthiness assessment 
revealed that interim actions are required for actuators p/n 9409122 
installed on fuel crossfeed valves and fuel fire shut-off valves 
until the new actuators are installed. Fokker Services have issued 
Service Bulletin (SB) SBF100-28-049 to introduce interim actions 
that will reduce the probability that fuel crossfeed and fuel fire 
shut-off valves equipped with actuators p/n 9409122 do not operate 
due to ice. The interim actions consist of an operational check of 
the actuators and the application of a grease layer on the 
actuators, followed by a weekly visual check of the applied grease 
layer and a 4-weekly operational check of the actuators.
    For the reasons stated above, this Airworthiness Directive (AD) 
requires compliance with instructions contained in the referenced 
SB. This AD has been re-published to correct typographical errors in 
the `Remarks' section, where the word `Proposed' should have been 
deleted.

EASA AD 2009-0116 states:

    Due to their position on the aeroplane, fuel crossfeed valve 
actuators P/N 9409122 are susceptible to freezing, which has an 
adverse effect on the operation of the valve. This condition, if not 
corrected, may generate fuel asymmetry alerts when a valve remains 
in the open position after being selected closed. It may also 
prevent the flight crew from correcting a fuel asymmetry when a 
valve remains in the closed position after being selected open. One 
event was reported where, due to such problems, the flight crew shut 
down an engine in-flight and diverted the aircraft.
    Aeroplanes with serial numbers 11244 through 11441 were 
delivered from the production line with actuators P/N 9401037 
(``chimney type'') installed. However, on some aeroplanes, these 
actuators have subsequently been replaced in service with actuators 
P/N 9409122 (using mounting blocks P/N 7923505) on one or both fuel 
crossfeed valves. As a result, those aeroplanes are also affected by 
this unsafe condition.
    To address and correct this unsafe condition, EASA issued AD 
2008-0126 that required the replacement of all P/N 9409122 fuel 
crossfeed valve actuators in accordance with Fokker Services SBF100-
28-046 with new actuators developed by the manufacturer Eaton 
Aerospace, P/N 53-0013, which have improved reliability and are less 
susceptible to freezing.
    Following the introduction of actuator P/N 53-0013 in service, 
Eaton Aerospace reported manufacturing and design errors on 
actuators with P/N 53-0013. As a result of these errors, the top-cap 
of the actuator may become loose, possibly leading to actuator 
failure. Eaton Aerospace has eliminated these problems by 
introducing a new actuator P/N 53-0027 and Fokker Services have 
published SBF100-28-061 to introduce these improved actuators on 
aeroplanes.
    As the compliance time of EASA AD 2008-0126 has not yet expired, 
both P/N 9409122 and P/N 53-0013 fuel crossfeed valve actuators can 
currently be installed on aeroplanes affected by this AD.
    For the reasons described above, this EASA AD retains the 
requirements of AD 2008-

[[Page 35606]]

0126, which is superseded, and adds the requirement to install the 
new P/N 53-0027 actuators. This AD also allows direct installation 
of P/N 53-0027 on aeroplanes that are still in pre-SBF100-28-046 
configuration, provided this is done within the compliance time as 
established for that SB in AD 2008-0126 and retained by this new AD.

EASA AD 2009-0168 states:

    Due to their position on the aeroplane, fuel fire shut-off valve 
actuators P/N 9409122 are susceptible to freezing, which has an 
adverse effect on the operation of the valve. Also, due to various 
causes, the failure rate of actuator P/N 9409122 is higher than 
expected. Failure or freezing of the actuator may prevent the flight 
crew to close the fuel fire shut-off valve in case of an engine 
fire.
    Aeroplanes serial numbers 11244 through 11441 were delivered 
from the production line with actuators P/N 9401037 (``chimney 
type'') installed. However, on some aeroplanes, these actuators have 
subsequently been replaced in service with actuators P/N 9409122 
(using mounting blocks P/N 7923505) on one or both fuel fire shut-
off valves. As a result, those aeroplanes are also affected by this 
unsafe condition.
    To address and correct this unsafe condition, EASA issued AD 
2008-0193, requiring the replacement of all P/N 9409122 fuel fire 
shut-off valve actuators with new actuators developed by the 
manufacturer Eaton Aerospace, P/N 53-0013, which have improved 
reliability and are less susceptible to freezing.
    Following the introduction of actuator P/N 53-0013 in service, 
Eaton Aerospace reported manufacturing and design errors on 
actuators with P/N 53-0013. As a result of these errors, the top-cap 
of the actuator may become loose, possibly leading to actuator 
failure. Eaton Aerospace has eliminated these problems by 
introducing a new actuator P/N 53-0027 and Fokker Services have 
published SBF100-76-020 to introduce these improved actuators on 
aeroplanes.
    As a consequence of EASA AD 2008-0193, both P/N 9409122 and P/N 
53-0013 fuel fire shut-off valve actuators are currently installed 
on aeroplanes affected by this AD.
    For the reasons described above, this EASA AD supersedes AD 
2008-0193 and requires the installation of new P/N 53-0027 
actuators. This AD also prohibits the installation of P/N 53-0013 
actuators in accordance with SBF100-76-018 (which has been 
cancelled), as previously required by EASA AD 2008-0193.

    You may obtain further information by examining the MCAI in the AD 
docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD will affect 2 products of U.S. registry. 
We also estimate that it will take about 23 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts will cost about $29,800 per 
product. Where the service information lists required parts costs that 
are covered under warranty, we have assumed that there will be no 
charge for these parts. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of this AD to the 
U.S. operators to be $63,510, or $31,755 per product.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this AD will not have federalism implications 
under Executive Order 13132. This AD will not have a substantial direct 
effect on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.
    For the reasons discussed above, I certify this AD:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979); and
    3. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://
www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.

[[Page 35607]]

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Fokker Services B.V. Model F.28 Mark 0070

numbers, if an actuator having part number (P/N) 9409122 or P/N 53-
0013 is installed on one or both fuel crossfeed valves or one or 
both fuel fire shut-off valves.

Subject

    (d) Air Transport Association (ATA) of America Code 28 and 76: 
Fuel and Engine Controls, respectively.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
consists of three EASA ADs: 2007-0122, dated May 3, 2007 (corrected 
May 7, 2007); 2009-0116, dated May 29, 2009; and MCAI 2009-0168, 
dated August 3, 2009. EASA AD 2007-0122 states:
    In-service experience revealed that, due to their position on 
the aircraft, ice may form on actuators P/N 9409122 installed on 
fuel crossfeed valves and fuel fire shut-off valves. Tests revealed 
that the ice can prevent the actuator and thus the valve from 
operating in flight (frozen stuck). A new actuator is being 
developed by Fokker Services. However, an airworthiness assessment 
revealed that interim actions are required for actuators p/n 9409122 
installed on fuel crossfeed valves and fuel fire shut-off valves 
until the new actuators are installed. Fokker Services have issued 
Service Bulletin (SB) SBF100-28-049 to introduce interim actions 
that will reduce the probability that fuel crossfeed and fuel fire 
shut-off valves equipped with actuators p/n 9409122 do not operate 
due to ice. The interim actions consist of an operational check of 
the actuators and the application of a grease layer on the 
actuators, followed by a weekly visual check of the applied grease 
layer and a 4-weekly operational check of the actuators.
    For the reasons stated above, this Airworthiness Directive (AD) 
requires compliance with instructions contained in the referenced 
SB. This AD has been re-published to correct typographical errors in 
the `Remarks' section, where the word `Proposed' should have been 
deleted.

EASA AD 2009-0116 states:

    Due to their position on the aeroplane, fuel crossfeed valve 
actuators P/N 9409122 are susceptible to freezing, which has an 
adverse effect on the operation of the valve. This condition, if not 
corrected, may generate fuel asymmetry alerts when a valve remains 
in the open position after being selected closed. It may also 
prevent the flight crew from correcting a fuel asymmetry when a 
valve remains in the closed position after being selected open. One 
event was reported where, due to such problems, the flight crew shut 
down an engine in-flight and diverted the aircraft.
    Aeroplanes with serial numbers 11244 through 11441 were 
delivered from the production line with actuators P/N 9401037 
(``chimney type'') installed. However, on some aeroplanes, these 
actuators have subsequently been replaced in service with actuators 
P/N 9409122 (using mounting blocks P/N 7923505) on one or both fuel 
crossfeed valves. As a result, those aeroplanes are also affected by 
this unsafe condition.
    To address and correct this unsafe condition, EASA issued AD 
2008-0126 that required the replacement of all P/N 9409122 fuel 
crossfeed valve actuators in accordance with Fokker Services SBF100-
28-046 with new actuators developed by the manufacturer Eaton 
Aerospace, P/N 53-0013, which have improved reliability and are less 
susceptible to freezing.
    Following the introduction of actuator P/N 53-0013 in service, 
Eaton Aerospace reported manufacturing and design errors on 
actuators with P/N 53-0013. As a result of these errors, the top-cap 
of the actuator may become loose, possibly leading to actuator 
failure. Eaton Aerospace has eliminated these problems by 
introducing a new actuator P/N 53-0027 and Fokker Services have 
published SBF100-28-061 to introduce these improved actuators on 
aeroplanes.
    As the compliance time of EASA AD 2008-0126 has not yet expired, 
both P/N 9409122 and P/N 53-0013 fuel crossfeed valve actuators can 
currently be installed on aeroplanes affected by this AD.
    For the reasons described above, this EASA AD retains the 
requirements of AD 2008-0126, which is superseded, and adds the 
requirement to install the new P/N 53-0027 actuators. This AD also 
allows direct installation of P/N 53-0027 on aeroplanes that are 
still in pre-SBF100-28-046 configuration, provided this is done 
within the compliance time as established for that SB in AD 2008-
0126 and retained by this new AD.

EASA AD 2009-0168 states:

    Due to their position on the aeroplane, fuel fire shut-off valve 
actuators P/N 9409122 are susceptible to freezing, which has an 
adverse effect on the operation of the valve. Also, due to various 
causes, the failure rate of actuator P/N 9409122 is higher than 
expected. Failure or freezing of the actuator may prevent the flight 
crew to close the fuel fire shut-off valve in case of an engine 
fire.
    Aeroplanes serial numbers 11244 through 11441 were delivered 
from the production line with actuators P/N 9401037 (``chimney 
type'') installed. However, on some aeroplanes, these actuators have 
subsequently been replaced in service with actuators P/N 9409122 
(using mounting blocks P/N 7923505) on one or both fuel fire shut-
off valves. As a result, those aeroplanes are also affected by this 
unsafe condition.
    To address and correct this unsafe condition, EASA issued AD 
2008-0193, requiring the replacement of all P/N 9409122 fuel fire 
shut-off valve actuators with new actuators developed by the 
manufacturer Eaton Aerospace, P/N 53-0013, which have improved 
reliability and are less susceptible to freezing.
    Following the introduction of actuator P/N 53-0013 in service, 
Eaton Aerospace reported manufacturing and design errors on

failure. Eaton Aerospace has eliminated these problems by 
introducing a new actuator P/N 53-0027 and Fokker Services have 
published SBF100-76-020 to introduce these improved actuators on 
aeroplanes.
    As a consequence of EASA AD 2008-0193, both P/N 9409122 and P/N 
53-0013 fuel fire shut-off valve actuators are currently installed 
on aeroplanes affected by this AD.
    For the reasons described above, this EASA AD supersedes AD 
2008-0193 and requires the installation of new P/N 53-0027 
actuators. This AD also prohibits the installation of P/N 53-0013 
actuators in accordance with SBF100-76-018 (which has been 
cancelled), as previously required by EASA AD 2008-0193.

Compliance

    (f) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Inspections and Tests for Fuel Crossfeed Valves and Fuel Fire Shut-Off 
Valves

    (g) For airplanes with an actuator having P/N 9409122 on one or 
both fuel crossfeed valves or one or both fuel fire shut-off valves: 
Within 30 days after the effective date of this AD, perform an 
operational test of, and application of grease on, the left-hand 
(LH) and right-hand (RH) fuel crossfeed valve actuators and fuel 
fire shut off valve actuators, in accordance with Part 1 of the 
Accomplishment Instructions of Fokker Service Bulletin SBF100-28-
049, dated April 3, 2007.

by paragraph (g) of this AD, and thereafter at intervals not to 
exceed 7 days, perform a general visual inspection of the applied 
grease layer on the LH and RH fuel crossfeed valve actuators and 
fuel fire shut off valve actuators, in accordance with Part 2 of the 
Accomplishment Instructions of Fokker Service Bulletin SBF100-28-
049, dated April 3, 2007. If the layer of grease on any valve 
actuator is found to be less than 2 to 3 millimeters, before further 
flight, reapply grease, in accordance with Part 1 of the 
Accomplishment Instructions of Fokker Service Bulletin SBF100-28-
049, dated April 3, 2007.
    (i) For airplanes equipped with an actuator having P/N 9409122 
on one or both fuel crossfeed valves or one or both fuel fire shut-
off valves: Within 28 days after completion of the actions required 
by paragraph (g) of this AD, and thereafter at intervals not to 
exceed 28 days, perform an operational test of the LH and RH fuel 
crossfeed valve actuators and fuel fire shut off valve actuators, in 
accordance with Part 3 of the Accomplishment Instructions of Fokker 
Service Bulletin SBF100-28-049, dated April 3, 2007.
    (j) During any of the tests required by paragraphs (g) and (i) 
of this AD, if a fuel fire shut-off valve actuator fails the 
operational test, before further flight, do the action specified in 
paragraph (j)(1) or (j)(2) of this AD.

[[Page 35608]]

    (1) Do the replacement specified in paragraph (l) of this AD.
    (2) Replace the valve actuator with a serviceable part having P/
N 9409122, using a method approved by either the Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA; 
or the European Aviation Safety Agency (or its delegated agent).

    Note 1: Guidance on replacing the valve actuator with a 
serviceable part can be found in the Fokker 70/100 Aircraft 
Maintenance Manual.

    (k) During any of the tests required by paragraphs (g) and (i) 
of this AD, if a fuel crossfeed valve actuator fails the operational 
test, before further flight, do the action specified in paragraph 
(k)(1) or (k)(2) of this AD.
    (1) Do the replacement specified in paragraph (o) of this AD.
    (2) Replace the valve actuator with a serviceable part having P/
N 9409122, using a method approved by either the Manager,

    Note 2: Guidance on replacing the valve actuator with a 
serviceable part can be found in the Fokker 70/100 Aircraft 
Maintenance Manual.

Replacement of Fuel Fire Shut-Off Valves

    (l) For airplanes equipped with an actuator having P/N 9409122 
on one or both fuel fire shut-off valves: Except as required by 
paragraph (j) of this AD, within 15 months after the effective date 
of this AD, replace each fuel fire shut-off valve actuator having P/
N 9409122 with a fuel fire shut-off valve actuator having P/N 53-
0027 and accomplish the associated modifications, in accordance with 
Part 1A or 1B, as applicable, of the Accomplishment Instructions of 
Fokker Service Bulletin SBF100-76-020, dated April 20, 2009. After 
installation of fuel fire shut-off valve actuators having P/N 53-
0027 on an airplane, the requirements of paragraphs (g), (h), and 
(i) of this AD no longer apply to the fuel fire shut-off valve 
actuators installed on that airplane.
    (m) For airplanes equipped with an actuator having P/N 53-0013 
on one or both fuel fire shut-off valves: Within 15 months after the 
effective date of this AD, replace each fuel fire shut-off valve 
actuator having P/N 53-0013 with a fuel fire shut-off valve actuator 
having P/N 53-0027, in accordance with Part 2 of the Accomplishment 
Instructions of Fokker Service Bulletin SBF100-76-020, dated April 
20, 2009.
    (n) As of the effective date of this AD, do not install a fuel

FAA AD Differences

    Note 3: This AD differs from the MCAI and/or service information 
as follows: Although paragraph (5) of EASA AD 2007-0122, dated May 
3, 2007, allows operating the airplane in accordance with the Master 
Minimum Equipment List (MMEL) Item 28-23-1 of MMEL Fokker 70/MMEL 
Fokker 100, paragraph (l) of this AD requires replacing affected 
valves before further flight.
