Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2009-0811; Directorate Identifier 2008-NE-41-AD]
RIN 2120-AA64

Airworthiness Directives; Rolls-Royce Corporation Turbofan
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede an existing airworthiness directive
(AD)

that applies to certain Rolls-Royce Corporation (RRC) AE 3007A series
turbofan engines. The existing AD currently requires removing certain
high-pressure turbine (HPT) stage 2 wheels, or performing inspections
on them, and reduces their approved life limits. This proposed AD would
clarify the AE 3007A turbofan engine model applicability, would further
reduce the approved life limits of affected HPT stage 2 wheels, and
would eliminate the inspections required by the existing AD. We are
proposing this AD to prevent uncontained failure of the HPT stage 2
wheel, damage to the engine, and damage to the airplane.

DATES: We must receive comments on this proposed AD by October 7, 2013.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion

    On September 1, 2010, we issued AD 2010-19-01, Amendment 39-16429
(75 FR 57660, September 22, 2010), for RRC AE 3007A series turbofan
engines with an HPT stage 2 wheel, part number (P/N) 23069438,
23069592, 23074462, 23074644, 23075345, or 23084520, installed. AD
2010-19-01 requires removing certain HPT stage 2 wheels, or performing
repetitive eddy current inspections (ECIs) or surface wave ultrasonic
test (SWUT) inspections on them for cracks. AD 2010-19-01 also reduces
the approved life limits of certain HPT stage 2 wheels. AD 2010-19-01
resulted from reports of cracked HPT stage 2 wheels. We issued AD 2010-
19-01 to prevent uncontained failure of the HPT stage 2 wheel, damage
to the engine, and damage to the airplane.

Actions Since Existing AD Was Issued

    Since we issued AD 2010-19-01 (75 FR 57660, September 22, 2010),
RRC did additional analysis and concluded that lower life limits for
the affected HPT stage 2 wheels are necessary. RRC based their results
on inspection data collected under AD 2010-19-01. In addition, we
determined that it is appropriate to establish the new lower life limit
to remove the parts from service, and to eliminate the inspection
requirements that were needed to provide additional data in support of
the analysis for the reduced life limits. We also changed the
applicability from RRC AE 3007A series turbofan engines to AE 3007A,
A1, A1/1, A1/2, A1/3, A1P, A1E, and A3 turbofan engines, for added
clarity. The AE 3007A2 turbofan engine is not included in the
applicability because affected HPT stage 2 wheels are not installed on
that engine.

Relevant Service Information

    We reviewed RRC Alert Service Bulletin (ASB) No. AE 3007A-A-72-414,
Revision 1, dated December 5, 2012. The ASB lists the lower approved
life limits of the affected HPT stage 2 wheels.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in RRC AE 3007A, A1, A1/1, A1/2, A1/3, A1P,
A1E, and A3 turbofan engines with affected HPT stage 2 wheels,
installed.

Proposed AD Requirements

    This proposed AD would clarify the AE 3007A turbofan engine model
applicability from stating AE 3007A series turbofan engines, to stating
AE 3007A, A1, A1/1, A1/2, A1/3, A1P, A1E, and A3 turbofan engines. This
proposed AD would also further reduce the approved life limits of
affected HPT stage 2 wheels, and would eliminate the initial and
repetitive ECIs and SWUT inspections on HPT stage 2 wheels for cracks
as required by the existing AD 2010-19-01 (75 FR 57660, September 22,
2010).

Costs of Compliance

    We estimate that this proposed AD would affect 18 engines installed
on airplanes of U.S. registry. We also estimate that a replacement HPT
stage 2 wheel would cost about $145,524, and that it would be replaced
during engine shop visit at no additional labor cost. Based on these
figures, we estimate the total cost of the AD to U.S. operators to be
$2,619,432.

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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD 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 that the 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 to the extent
that it justifies making a regulatory distinction, 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 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 removing airworthiness directive (AD)
2010-19-01, Amendment 39-16429 (75 FR 57660, September 22, 2010), and
adding the following new AD:

Roll-Royce Corporation (Formerly Allison Engine Company): Docket No.
FAA-2009-0811; Directorate Identifier 2008-NE-41-AD.

(a) Comments Due Date

    The FAA must receive comments on this AD action by October 7,
2013.

(b) Affected ADs

    This AD supersedes AD 2010-19-01, Amendment 39-16429 (75 FR
57660, September 22, 2010).

(c) Applicability

    This AD applies to the following Rolls-Royce Corporation (RRC)
AE 3007A, A1, A1/1, A1/2, A1/3, A1P, A1E, and A3 turbofan engines:
    (1) With an installed high-pressure turbine (HPT) stage 2 wheel,
part number (P/N) 23084520, or
    (2) With an installed HPT stage 2 wheel, P/N 23069438, 23069592,
23074462, 23074644, or 23075345, except for the HPT stage 2 wheel
serial numbers listed in Table 2 through Table 5 of RRC Alert
Service Bulletin (ASB) No. AE 3007A-A-72-414, Revision 1, dated
