DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2011-1226; Directorate Identifier 2011-NM-006-AD; 
Amendment 39-17001; AD 2012-06-20]
RIN 2120-AA64


Airworthiness Directives; Fokker Services B.V. Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This AD 
was prompted by a report that the fuel crossfeed valves cannot be 
controlled when only emergency electrical power is available, that an 
unwanted configuration of the indication logic for the fuel fire 
shutoff valve was introduced during production, and that current fuel 
crossfeed indications are based on selection by the flightcrew instead 
of actual position of the crossfeed valve actuators. This AD requires 
modifying the crossfeed valve control and power supply, the crossfeed 
indication logic and power supply, and the indication logic for the 
fuel fire shutoff valve; modifying the overhead panel; and for certain 
airplanes, modifying the transfer logic of the center wing fuel tank. 
We are issuing this AD to prevent failure of an in-flight engine re-
light following a double engine flame-out event, which could result in 
loss of the airplane.

DATES: This AD becomes effective May 24, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of May 24, 2012.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC.

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 November 8, 2011 (76 
FR 69163). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    A recent safety review revealed that the fuel crossfeed valves 
cannot be controlled when only emergency electrical power is 
available.
    This condition, if not corrected, could (in combination with 
other factors) prevent an in-flight engine re-light following a 
double engine flame-out event, possibly resulting in loss of the 
aeroplane.
    Another review revealed that an unwanted configuration of the 
fuel fire shut-off valve indication logic had been introduced during 
production on a limited number of F28 Mark 0100 aeroplanes.
    Furthermore, most of the current fuel crossfeed indications are 
based on the crossfeed selection made by the flight crew and not on 
the actual positions of the crossfeed valve actuators. In 
combination with other factors, the current crossfeed indications 
may mislead flight crews, possibly resulting in single engine in-
flight shutdowns and/or unnecessary precautionary landings.
    For the reasons described above, this [EASA] AD requires 
modifications of the crossfeed valve control and power supply, of 
the crossfeed indication logic and power supply and of the fuel fire 
shut-off valve indication logic.
* * * * *
Required actions also include modifying the overhead panel (introducing 
provisions for a modified crossfeed indication), and, for certain 
airplanes, modifying the transfer logic of the center wing fuel tank. 
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 69163, November 8, 
2011) or on the determination of the cost to the public.

Explanation of Changes Made to This AD

    We have revised the heading for and the wording in paragraph (i) of 
this AD; this change has not changed the intent of that paragraph. We 
have also revised the document citations throughout this AD to more 
clearly identify the documents and their attachments.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting the AD with the changes described 
previously--and minor editorial changes. We have determined that these 
minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (76 FR 69163, November 8, 2011) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (76 FR 69163, November 8, 2011).

Costs of Compliance

    We estimate that this AD will affect 6 products of U.S. registry. 
We also estimate that it will take about 86 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 $4,180 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 $68,940, or $11,490 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

[[Page 23386]]

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 proposed 
regulation:
    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);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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 69163, November 8, 
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.
