[Docket No. FAA-2011-0568; Directorate Identifier 2011-NM-010-AD; 
Amendment 39-16824; AD 2011-21-01]
RIN 2120-AA64


Airworthiness Directives; Fokker Services B.V. Model F.27 Mark 
050, 200, 300, 400, 500, 600, and 700 Airplanes; and Model F.28 
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:

    [T]he Federal Aviation Administration (FAA) has published 
Special Federal Aviation Regulation (SFAR) 88, and the Joint 
Aviation Authorities (JAA) has published Interim Policy INT/POL/25/
12. The review conducted by Fokker Services on the Fokker F27 and 
F28 type designs in response to these regulations revealed that, 
under certain failure conditions, a short circuit can develop in the 
fuel pilot valve solenoid or in the wiring to the solenoid. Such a 
short circuit may result in an ignition source in the wing tank 
vapour space.
    This condition, if not corrected, could result in a wing fuel 
tank explosion and consequent loss of the aeroplane.
* * * * *
We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective November 16, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 16, 
2011.

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 June 21, 2011 (76 FR 
36011). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    [T]he Federal Aviation Administration (FAA) has published 
Special Federal Aviation Regulation (SFAR) 88, and the Joint 
Aviation Authorities (JAA) has published Interim Policy INT/POL/25/
12. The review conducted by Fokker Services on the Fokker F27 and 
F28 type designs in response to these regulations revealed that, 
under certain failure conditions, a short circuit can develop in the 
fuel pilot valve solenoid or in the wiring to the solenoid. Such a 
short circuit may result in an ignition source in the wing tank 
vapour space.
    This condition, if not corrected, could result in a wing fuel 
tank explosion and consequent loss of the aeroplane.
    For the reasons described above, this AD requires [re-working 
the wiring and] the installation of a fuse packed in a jiffy 
junction [i.e., crimped wire in-line junction device] in the wiring 
to the fuel pilot valve solenoid.

The required actions also include revising the maintenance program to 
include a certain Critical Design Configuration Control Limitation 
(CDCCL). 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 (76 FR 36011, June 21, 
2011) 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 6 products of U.S. registry. 
We also estimate that it will take about 6 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 up to $2,198 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 up to $16,248, or up to $2,708 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 (76 FR 36011, June 21, 2011), 
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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2011-21-01 Fokker Services B.V.: Amendment 39-16824. Docket No. FAA-
2011-0568; Directorate Identifier 2011-NM-010-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective November 
16, 2011.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Fokker Services B.V. Model F.27 Mark 050, 
200, 300, 400, 500,

[[Page 63158]]

600, and 700 airplanes; and Fokker Services B.V. Model F.28 Mark 
0070, 0100, 1000, 2000, 3000, and 4000 airplanes; certificated in 
any category; all serial numbers.

    Note 1:  This AD requires revisions to certain operator 
maintenance documents to include a new Critical Design Configuration 
Control Limitation (CDCCL). Compliance with this CDCCL is required 
by 14 CFR 91.403(c). For airplanes that have been previously 
modified, altered, or repaired in the areas addressed by this AD, 
the operator may not be able to accomplish the actions described in 
the revisions. In this situation, to comply with 14 CFR 91.403(c), 
the operator must request approval for an alternative method of 
compliance (AMOC) according to paragraph (j)(1) of this AD. The 
request should include a description of changes to the required 
inspections that will ensure the continued operational safety of the 
airplane.

Subject

    (d) Air Transport Association (ATA) of America Code 28: Fuel.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    [T]he Federal Aviation Administration (FAA) has published 
Special Federal Aviation Regulation (SFAR) 88, and the Joint 
Aviation Authorities (JAA) have published Interim Policy INT/POL/25/
12. The review conducted by Fokker Services on the Fokker F27 and 
F28 type designs in response to these regulations revealed that, 
under certain failure conditions, a short circuit can develop in the 
fuel pilot valve solenoid or in the wiring to the solenoid. Such a 
short circuit may result in an ignition source in the wing tank 
vapour space.
    This condition, if not corrected, could result in a wing fuel 
tank explosion and consequent loss of the aeroplane.
* * * * *

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.

Installation of Fuses Packed in Jiffy Junctions

    (g) Within 24 months after the effective date of this AD, re-
work the wiring and install the fuses packed in jiffy junctions 
(i.e., crimped wire in-line junction device), in accordance with the 
Accomplishment Instructions of the applicable Fokker service 
bulletin identified in table 1 of this AD.

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

Critical Design Configuration Control Limitation (CDCCL)

    (h) Before further flight after doing the actions required by 
paragraph (g) of this AD: Revise the aircraft maintenance program by 
incorporating the CDCCL specified in paragraph 1.L.(1)(c) of the 
applicable Fokker service bulletins identified in table 1 of this 
AD.

No Alternative Actions, Intervals, and/or CDCCLs

    (i) After accomplishing the revision required by paragraph (h) 
of this AD, no alternative CDCCLs may be used unless the CDCCLs are 
approved as an alternative method of compliance (AMOC) in accordance 
with the procedures specified in paragraph (j)(1) of this AD.

FAA AD Differences

    Note 2:  This AD differs from the MCAI and/or service 
information as follows:
    Although European Aviation Safety Agency (EASA) Airworthiness 
Directive 2010-0195, dated September 29, 2010, specifies revising 
the maintenance program to include maintaining CDCCLs, this AD only 
requires the revision. Requiring a revision of the maintenance 
program, rather than requiring maintaining CDCCLs, requires 
operators to record AD compliance only at the time the revision is 
made. Maintaining CDCCLs specified in the airworthiness limitations 
must be complied with in accordance with 14 CFR 91.403(c).

Other FAA AD Provisions

    (j) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance: The Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
has the authority to approve AMOCs for this AD, if requested using 
the procedures found in 14 CFR 39.19. In accordance with 14 CFR 
39.19, send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the International Branch, send it to ATTN: Tom 
Rodriguez, Aerospace Engineer, International Branch, ANM-116, 
Transport Airplane Directorate, FAA 1601 Lind Avenue, SW., Renton, 
Washington 98057-3356; telephone 425-227-1137; fax 425-227-1149. 
Information may be e-mailed to: 9-ANM-11-AMOC-REQUESTS@faa.gov. 
Before using any approved AMOC, notify your appropriate principal 
inspector, or lacking a principal inspector, the manager of the 
local flight standards district office/certificate holding district 
office. The AMOC approval letter must specifically reference this 
AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
