We are adopting a new airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211-535E4-37, RB211-535E4-B-37, and RB211-535E4- C-37 turbofan engines. This AD requires recalculating the cyclic life for certain engine life-limited rotating parts and removing those parts that have exceeded their cyclic life limit within specified compliance times. This AD was prompted by a review of operational data that determined certain RR RB211-535E4-37 engines have been operated to a more severe flight profile than is consistent with the flight profile used to establish the cyclic life limits for the rotating parts. We are issuing this AD to prevent failure of life-limited rotating parts, uncontained parts release, damage to the engine, and damage to the airplane.

Airworthiness Directives; Rolls-Royce plc Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Rolls-Royce plc (RR) RB211-535E4-37, RB211-535E4-B-37, and RB211-535E4-
C-37 turbofan engines. This AD requires recalculating the cyclic life 
for certain engine life-limited rotating parts and removing those parts 
that have exceeded their cyclic life limit within specified compliance 
times. This AD was prompted by a review of operational data that 
determined certain RR RB211-535E4-37 engines have been operated to a 
more severe flight profile than is consistent with the flight profile 
used to establish the cyclic life limits for the rotating parts. We are 
issuing this AD to prevent failure of life-limited rotating parts, 
uncontained parts release, damage to the engine, and damage to the 
airplane.

DATES: This AD becomes effective March 15, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 15, 
2016.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to the specified products. The 
NPRM was published in the Federal Register on November 4, 2015 (80 FR 
68284). The NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    A review of operational flight data has revealed that some 
RB211-535 engines may have been operated beyond the flight profile 
(FP) assumed by the operator when establishing the operational 
limits (life limits) within which the corresponding critical parts 
are allowed to remain installed.
    This condition, if not corrected, may lead to critical part 
failure, possibly resulting in release of high energy debris, damage 
to the aeroplane and/or injury to the occupants.

    To preclude failure of an engine life-limited part, the MCAI 
specifies, and this AD would require, recalculating the cyclic life for 
certain parts and removing from service those parts that have exceeded 
their cyclic life limit within specified compliance times. This AD 
would establish a new default Flight Profile G for RR RB211-535E4-37 
engine life-limited parts. If, however, operators meet the requirements 
of Appendix 6 of RR Alert Non-Modification Service Bulletin (NMSB) No. 
RB.211-72-AH972, Revision 3, dated August 28, 2015, they may operate to 
Flight Profile A or B. You may obtain further information by examining 
the MCAI in the AD docket on the Internet at http://www.regulations.gov 
by searching for and locating Docket No. FAA-2015-3778.

Related Service Information Under 1 CFR Part 51

    We reviewed RR Alert NMSB No. RB.211-72-AH972, Revision 3, dated 
August 28, 2015. The Alert NMSB describes a new flight profile, 
provides procedures for the consumed cyclic life corrections for prior 
operation of affected parts, and provides the removal from service 
recommendations for parts that have exceeded their cyclic life limit. 
This service information is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section of this AD.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comments received.

[[Page 6756]]

Support for the NPRM (80 FR 68284, November 4, 2015)

    The Boeing Company, FedEx, United Airlines, and American Airlines 
expressed support for the NPRM.

Request To Change Actions and Compliance

    United Parcel Service (UPS) requested that the NPRM recognize 
digital flight data taken from either the digital flight data recorder 
(DFDR) or the digital flight data acquisition unit (DFDAU) as valid 
data for RR RB211 flight profile monitoring purposes. The data captured 
by the DFDAU is recorded on the DFDR, but DFDAUs are regularly 
downloaded for UPS' flight operations quality assurance program. The 
DFDAU data is easier to access than pulling a DFDR for data download 
purposes.
    We agree. We added a new paragraph to paragraph (e)(1) of this AD 
as follows: ``(e)(1)(iv) You may use data from either a digital flight 
data acquisition unit or a digital flight data recorder for flight 
profile monitoring.''.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously. We determined that these 
changes will not increase the economic burden on any operator or 
increase the scope of this AD.

Costs of Compliance

    We estimate that this AD affects 107 engines installed on airplanes 
of U.S. registry. Pro-rated cost of the lost cyclic life as a result of 
the corrections would be about $25,417,324. We estimate it will take 1 
hour to recalculate the consumed cyclic life and revise the engine 
records which include 5 minutes (0.083 hours) for record entries. The 
average labor rate is $85 per hour. Based on these figures, we estimate 
the cost of this AD on U.S. operators to be $25,426,419.

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 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 AD:
    (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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

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 adding the following new airworthiness 
directive (AD):

2016-03-04 Rolls-Royce plc: Amendment 39-18391; Docket No. FAA-2015-
3778; Directorate Identifier 2015-NE-27-AD.

(a) Effective Date

    This AD becomes effective March 15, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Rolls-Royce plc (RR) RB211-535E4-37, 
RB211-535E4-B-37, and RB211-535E4-C-37 turbofan engines.

(d) Reason

    This AD was prompted by a review of operational data that 
determined that certain RR RB211-535E4-37 engines have been operated 
to a more severe flight profile than is consistent with the flight 
profile used to establish the cyclic life limits for the rotating 
parts. We are issuing this AD to prevent failure of life-limited 
rotating parts, which could result in uncontained parts release, 
damage to the engine, and damage to the airplane.

(e) Actions and Compliance

    Comply with this AD within the compliance times specified, 
unless already done. Within 21 days after the effective date of this 
AD:
    (1) For RR RB211-535E4-37 engines, establish a new flight 
profile, Flight Profile G, as the new default profile for flight 
operations and new part lives for life-limited parts.
    (i) Use Appendix 6 of RR Alert Non-Modification Service Bulletin 
(NMSB) No. RB.211-72-AH972, Revision 3, dated August 28, 2015, to 
define Flight Profile G.
    (ii) Use the definition of Flight Profile G in Appendix 6 and 
the maximum approved cyclic lives in Appendix 2 of RR Alert NMSB No. 
RB.211-72-AH972, Revision 3, dated August 28, 2015, to identify the 
new lives for life-limited parts.
    (iii) If operators meet the requirements of Appendix 6 of RR 
Alert NMSB No. RB.211-72-AH972, Revision 3, dated August 28, 2015, 
they may operate to Flight Profile A or B.
    (iv) You may use data from either a digital flight data 
acquisition unit or a digital flight data recorder for flight 
profile monitoring.
    (2) For all RR RB211-535E4-37, RB211-535E4-B-37, and RB211-
535E4-C-37 engines, determine if any part identified by part number 
and serial number in Appendix 4 of RR Alert NMSB No. RB.211-72-
AH972, Revision 3, dated August 28, 2015, is installed on the 
engine.
    (i) Do not return to service any engine with a part identified 
in paragraph (e)(2) of this AD after the part reaches the 
``Compliance Time'' date or cycles, whichever occurs first, as 
specified in Appendix 4 of RR Alert NMSB No. RB.211-72-AH972, 
Revision 3, dated August 28, 2015.
    (ii) For each part identified in paragraph (e)(2) of this AD 
without a ``Compliance Time'' that has a lifing correction 
identified, apply the lifing correction for each part using the 
``Additional Life Consumed Flight Cycles'' specified in Appendix 4 
of RR Alert NMSB No. RB.211-72-AH972, Revision 3, dated August 28, 
2015.
    (3) For RR RB211-535E4-37 engines operated to Flight Profile G 
with parts listed in Appendix 4 of RR Alert NMSB No. RB.211-72-
AH972, Revision 3, dated August 28, 2015, do the following:
    (i) Re-calculate the consumed cyclic life of the low-pressure 
(LP) compressor shaft, LP turbine shaft, LP turbine disk Stage 2,

[[Page 6757]]

intermediate-pressure compressor rotor shaft Stage 1 to 6, high-
pressure (HP) compressor rotor disk Stage 1 and 2, HP compressor 
rear rotor shaft assembly, and HP turbine disk as follows.
    (ii) Determine the Flight Profile G cycles in service (CIS). 
Count all CIS accumulated since April 1, 2015, inclusive.
    (iii) Use the Flight Profile G cycles in service from paragraph 
(e)(3)(ii) of this AD, the maximum approved lives in Appendix 2 of 
RR Alert NMSB No. RB.211-72-AH972, Revision 3, dated August 28, 
2015, and Figure 1 to paragraph (e) of this AD to calculate the new 
consumed cyclic lives.
