Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30 
and DC-10-30F (KC-10A and KDC-10) airplanes; Model DC-10-40 and DC-10-
40F airplanes; and Model MD-11 and MD-11F airplanes. This AD requires, 
for certain airplanes, modifying the thrust reverser command wiring of 
the number 2 engine. For certain other airplanes, this AD requires 
modifying the thrust

[[Page 71207]]

reverser system wiring from the flight compartment to engines 1, 2, and 
3 thrust reversers. This AD also requires installing thrust reverser 
locking systems on certain airplanes. This AD results from a 
determination that the thrust reverser systems on these McDonnell 
Douglas airplanes do not adequately preclude unwanted deployment of a 
thrust reverser. We are issuing this AD to prevent an unwanted 
deployment of a thrust reverser during flight, which could result in 
reduced controllability of the airplane.

DATES: This AD becomes effective January 22, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of January 22, 
2008.
    On October 1, 2001 (66 FR 44950, August 27, 2001), the Director of 
the Federal Register approved the incorporation by reference of 
McDonnell Douglas Service Bulletin DC10-78-060, dated December 17, 
1999.
    On April 25, 2001 (66 FR 15785, March 21, 2001), the Director of 
the Federal Register approved the incorporation by reference of 
McDonnell Douglas Alert Service Bulletin DC10-78A057, Revision 01, 
dated February 18, 1999.

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a supplemental notice of proposed rulemaking (NPRM) 
to amend 14 CFR part 39 to include an AD that would apply to certain 
McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30 and DC-
10-30F (KC-10A and KDC-10) airplanes; Model DC-10-40 and DC-10-40F 
airplanes; and Model MD-11 and MD-11F airplanes. That supplemental NPRM 
was published in the Federal Register on July 23, 2007 (72 FR 40090). 
That supplemental NPRM proposed to require, for certain airplanes, 
modifying the thrust reverser command wiring of the number 2 engine. 
For certain other airplanes, the supplemental NPRM proposed to require 
modifying the thrust reverser system wiring from the flight compartment 
to engines 1, 2, and 3 thrust reversers. The supplemental NPRM also 
proposed to require installing thrust reverser locking systems on 
certain airplanes. The supplemental NPRM also proposed to revise the 
original NPRM by revising, for certain airplanes, the requirements for 
the modification of the thrust reverser system wiring from the flight 
compartment to engines 1, 2, and 3 thrust reversers.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comment received.

Request for Notification of Service Bulletin/Rulemaking

    FedEx requests that we and/or Boeing notify operators of any 
service bulletin or rulemaking that will cover Model MD-11 and MD-11F 
airplanes that are not specified in Boeing Alert Service Bulletin MD11-
78A007, Revision 4, dated February 22, 2007 (which is referred to as a 
source of service information for doing a modification specified in the 
supplemental NPRM). FedEx states that it has no comments on the 
proposed requirements of the supplemental NPRM.
    We acknowledge FedEx's request. We have been advised that when a 
service bulletin is released Boeing does notify the customers affected 
by the service bulletin. If service information is developed for other 
Model MD-11 and MD-11F airplanes and an unsafe condition is identified, 
we might consider further rulemaking. Interested persons can review the 
Federal Register to become aware of such rulemaking actions.

Conclusion

    We have carefully reviewed the available data, including the 
comment received, and determined that air safety and the public 
interest require adopting the AD as proposed in the supplemental NPRM.

Costs of Compliance

    There are about 612 airplanes of the affected designs in the 
worldwide fleet. This AD affects about 245 airplanes of U.S. registry. 
The following tables provide the estimated costs for U.S. operators to 
comply with this AD, for the applicable actions, at an average hourly 
labor rate of $80 per work hour.

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 have 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under 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. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
