We are superseding Airworthiness Directive (AD) 2015-15-03 for all General Electric Company (GE) GEnx turbofan engine models. AD 2015- 15-03 precluded the use of certain electronic engine control (EEC) full authority digital engine control (FADEC) software on GEnx turbofan engines. This AD requires removing a specific part and replacing it with a part eligible for installation and specifying the EEC FADEC software version for the affected GEnx turbofan engines. This AD was prompted by GE implementing final design changes that remove the unsafe condition. We are issuing this AD to correct the unsafe condition on these products.

SUMMARY: We are superseding Airworthiness Directive (AD) 2015-15-03 for 
all General Electric Company (GE) GEnx turbofan engine models. AD 2015-
15-03 precluded the use of certain electronic engine control (EEC) full 
authority digital engine control (FADEC) software on GEnx turbofan 
engines. This AD requires removing a specific part and replacing it 
with a part eligible for installation and specifying the EEC FADEC 
software version for the affected GEnx turbofan engines. This AD was 
prompted by GE implementing final design changes that remove the unsafe 
condition. We are issuing this AD to correct the unsafe condition on 
these products.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2015-15-03, Amendment 39-18212 (80 FR 42707, 
July 20, 2015), (``AD 2015-15-03''). AD 2015-15-03 applied to all GE 
GEnx turbofan engine models. The NPRM published in the Federal Register 
on November 3, 2016 (81 FR 76540). The NPRM was prompted by GE 
implementing final design changes that remove the unsafe condition. The 
NPRM proposed to remove a specific part and replace it with a part 
eligible for installation and specify the EEC FADEC software version 
for the affected GEnx turbofan engines. We are issuing this AD to 
prevent engine failure, loss of thrust control, and damage to the 
airplane.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM and 
the FAA's response to each comment.

Request To Change Compliance

    The Boeing Company and GE requested that we amend paragraph (f) to 
clarify which software versions are prohibited from being installed. 
They stated that the listed software versions do not contain the 
highest level of ice crystal icing (ICI) accommodation.
    We agree. We revised this AD because the listed software versions 
do not contain the highest level of ICI accommodation features. Also, 
the change requested makes the prohibition statement consistent with 
the AD removal requirements.

Request To Add Terminating Action

    The Boeing Company requested that we add compliance to this AD as a 
terminating action to AD 2013-24-01, Amendment 39-17675 (78 FR 70851, 
November 27, 2013), (``AD 2013-24-01'') since it removes the unsafe 
condition.
    We partially agree. We agree that complying with this AD is 
terminating action for certain requirements of AD 2013-24-01. 
Therefore, we added a new terminating action paragraph (h) of this AD. 
Since complying with this AD is terminating action to certain 
requirements of AD 2013-24-01, we disagree that complying with this AD 
is terminating action for all requirements of AD 2013-24-01.

Request To Add Terminating Action

    The Boeing Company requests that 747-8 and 747-8F aircraft with 
GEnx-2B engines that are operating with software, version C075, be 
granted a relaxation of the requirements in paragraphs (g) and (h) of 
AD 2013-24-01. They stated that an alternative method of compliance 
(AMOC) exists that grants a relaxation of the requirements of 
paragraphs (g) and (h) of AD 2013-24-01 as long as the aircraft engines 
have the required software versions.
    We disagree. Although Transport Airplane Directorate issued 
aircraft level AD 2013-24-01 and granted an AMOC, those are interim 
actions. Complying with this AD is required to remove the unsafe 
condition and is terminating action to certain requirements of AD 2013-
24-01. We did not change this AD.

Request To Revise a Definition

    GE requested that we revise the definition of an engine shop visit. 
They suggested that we add ``Workscopes involving only externals, 
including transfer gearbox (TGB) and accessory gearbox (AGB) do not 
constitute an engine shop visit for the purpose of this AD.''
    We disagree. The definition of a shop visit as ``the induction of 
an engine into the shop for maintenance involving the separation of 
pairs of major mating engine case flanges'' is a standard industry 
definition. Workscopes involving the TGB/AGB, or externals, do not 
separate major mating engine case flanges and do not constitute an 
engine shop visit for the purpose of this AD. We did not change this 
AD.

Request To Change Compliance Time

    Cathay Pacific Airways Limited requested that we clarify which 
parts may be installed into the engine.
    We disagree. The FAA does not intend to specify which parts may be 
installed into the engine, only those parts that may not be installed 
into the engine. Specifying which parts are eligible for installation 
may inadvertently prohibit new parts that are introduced from being 
installed into the engine. We did not change this AD.

Agreement With the Proposed AD

    The Air Line Pilots Association expressed agreement with this AD.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously. We determined that the 
changes we made as the result of the comments we received:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic

[[Page 21113]]

burden on any operator or increase the scope of this AD.

Related Service Information

    We reviewed GE GEnx-2B Service Bulletin (SB) 72-0241 R00, dated 
March 16, 2016 that describes removal and installation procedures of 
fan hub stator assembly booster outlet guide vane; GE GEnx-2B SB 73-
0041 R00, dated July 2, 2015 that describes reprogramming procedures 
for EEC FADEC software, version C075; and GE GEnx-1B SB 73-0044 R00, 
dated July 1, 2015 that describes reprograming procedures for EEC FADEC 
software, version B185.

Costs of Compliance

    We estimate that this AD affects 130 engines installed on airplanes 
of U.S. registry. We estimate that it would take about 1 hour per 
engine to comply with the software installation required by this AD. We 
also estimate that 32 engines would require hardware replacement, which 
would take about 60 hours per engine. Required parts cost about 
$390,000 per engine. 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 
$12,654,250.

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),
    (3) Will not affect intrastate aviation in Alaska, 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.
