14 CFR Part 39
[Docket No. FAA-2010-0960; Directorate Identifier 98-ANE-09-AD]
RIN 2120-AA64
Airworthiness Directives; Rolls-Royce plc RB211-Trent 768, 772,
and 772B Turbofan Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM); rescission.
-----------------------------------------------------------------------
SUMMARY: We propose to rescind an airworthiness directive (AD) for the
products listed above. The existing AD, AD 98-09-27, resulted from
aircraft certification testing which revealed that stresses on the
thrust reverser hinge were higher than had been anticipated during
engine certification, and the United Kingdom Civil Aviation Authority,
issuing AD 008-03-97.
Since we issued AD 98-09-27, we discovered that its requirements
were duplicated in airplane-level AD 2001-09-14, issued by the FAA
Transport Airplane Directorate. This proposal to rescind the engine-
level AD allows the public the opportunity to comment on the FAA's
determination of the duplication of requirements in another AD, before
we rescind the engine-level AD.
DATES: We must receive comments on this proposed AD by December 30,
2010.
ADDRESSES: You may send comments by any of the following methods:
Federal eRulemaking Portal: Go to http://www.regulations.gov, and follow the instructions for sending your
comments electronically.
Mail: Docket Management Facility, U.S. Department of
Transportation, 1200 New Jersey Avenue, SE., West Building Ground
Floor, Room W12-140, Washington, DC 20590-0001.

a.m. and 5 p.m., Monday through Friday, except Federal holidays.
Fax: (202) 493-2251.

Discussion
On April 23, 1998, the FAA Engine & Propeller Directorate issued
engine AD 98-09-27 (63 FR 24911, May 6, 1998). On April 30, 2001, the
FAA Transport Airplane Directorate issued airplane AD 2001-09-14 (66 FR
23838, May 10, 2001). Those ADs both require the same initial and
repetitive visual inspections of Rolls-Royce plc RB211-Trent 768 and
772 series turbofan engine thrust reverser hinge lugs and attachment
ribs for cracks, and, if necessary, removal from service and
replacement with serviceable parts.
Since we issued engine AD 98-09-27 and airplane AD 2001-09-14, we
determined that duplicate ADs to address the same unsafe condition were
unnecessary.
FAA's Determination and Requirements of This Proposed AD Rescission
We are proposing this AD rescission of AD 98-09-27 because we
evaluated all information and determined that two FAA ADs with the same
requirements are not necessary.
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 proposed AD rescission would not have
federalism implications under Executive Order 13132. This proposed AD
rescission would 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 rescission
of a 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); 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 proposed AD rescission and placed it in the AD docket.
List of Subjects in 14 CFR Part 39

The Proposed Amendment
Accordingly, under the authority delegated to me by the
