Amendment 39-15302; AD 2007-25-20]

Airworthiness Directives; 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

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.
