We are superseding Airworthiness Directive (AD) 2017-20-06 for certain Honeywell International Inc. (Honeywell) AS907-1-1A turbofan engines. AD 2017-20-06 required a one-time inspection of the second stage low-pressure turbine (LPT2) blades and, if the blades fail the inspection, the replacement of the blades with a part eligible for installation. This AD continues to require a one-time inspection of the LPT2 blades and, if the blades fail the inspection, the replacement of the blades with a part eligible for installation. This AD was prompted by the need to clarify the Applicability and Compliance sections of AD 2017-20-06. We are issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Honeywell International Inc. Turbofan 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2017-20-06 for 
certain Honeywell International Inc. (Honeywell) AS907-1-1A turbofan 
engines. AD 2017-20-06 required a one-time inspection of the second 
stage low-pressure turbine (LPT2) blades and, if the blades fail the 
inspection, the replacement of the blades with a part eligible for 
installation. This AD continues to require a one-time inspection of the 
LPT2 blades and, if the blades fail the inspection, the replacement of 
the blades with a part eligible for installation. This AD was prompted 
by the need to clarify the Applicability and Compliance sections of AD 
2017-20-06. We are issuing this AD to address the unsafe condition on 
these products.

DATES: This AD is effective November 19, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 9, 
2017 (82 FR 46379, October 5, 2017).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2017-20-06, Amendment 39-19063 (82 FR 46379, 
October 5, 2017), (``AD 2017-20-06''). AD 2017-20-06 applied to certain 
Honeywell International Inc. (Honeywell) AS907-1-1A turbofan engines. 
The NPRM published in the Federal Register on January 30, 2018 (83 FR 
4167). The NPRM was prompted by the need to clarify the Applicability 
and Compliance sections of AD 2017-20-06. The NPRM proposed to continue 
to require one-time inspection of the LPT2 blades and, if the blades 
fail the inspection, the replacement of the blades with a part eligible 
for installation. We are issuing this AD to address the unsafe 
condition on these products.

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 Align the Compliance Requirements With the Service Bulletin 
(SB)

    Bombardier Aerospace (Bombardier) requested that the compliance

[[Page 51830]]

requirements of the AD be aligned with Honeywell SB AS907-72-9067, 
Revision 1, dated March 20, 2017. Bombardier asked that we remove the 
requirements for measured wear requirements for recording of wear. 
Bombardier noted that Honeywell SB AS907-72-9067 requires contact 
between the LPT2 rotor blade Z-gap.
    We disagree. Honeywell SB AS907-72-9067, Revision 1, dated March 
20, 2017 and the compliance section of this AD provide the same 
guidance for measuring and recording wear with a borescope at the LPT2 
blade shroud Z-gap. Reported borescope inspections of high-time engines 
show that blade-to-blade contact at the Z-gap is difficult to measure 
with a borescope. The FAA and Honeywell agree that the measured wear 
limit of 0.005'', as defined by the Honeywell Light Maintenance Manual 
(LMM) AS907-1-1A, 72-00-00, is acceptable for this AD.
    Additionally, the FAA disagrees with the request to remove the 
requirement for recordings of the borescope inspection. We find that 
making these recordings with a clean digital image helps us to identify 
wear characteristics, severity, and cumulative damage of LPT2 blade 
assembly and to provide future borescope requirements for LPT blade 
maintenance. We did not change this AD.

Request To Revise Costs of Compliance

    Bombardier Aerospace requested that we align the cost estimates in 
this AD with the cost estimates in Honeywell's SB.
    We disagree. The slight differences in costs between the NPRM and 
Honeywell's SB reflect the additional recording requirements in this 
AD. We did not change this AD.

Revision to Applicability

    The intent of the NPRM was to limit the applicability of this AD to 
affected blades that have more than 8,000 hours since new on November 
9, 2017 (the effective date of AD 2017-20-06). We therefore revised the 
applicability to refer to ``November 9, 2017,'' instead of ``the 
effective date of 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 as proposed.

Related Service Information Under 1 CFR Part 51

    We reviewed Honeywell SB AS907-72-9067, Revision 1, dated March 20, 
2017. This SB describes procedures for inspecting the LPT2 blades. 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.

Other Related Service Information

    We reviewed Honeywell SB AS907-72-9067, Revision 0, dated December 
12, 2016, which also describes procedures for inspecting the LPT2 
blades. We also reviewed the Honeywell LMM AS907-1-1A, 72-00-00, 
Section 72-05-12, dated May 25, 2016, and Section 72-55-03, dated 
September 27, 2011, which provide additional guidance for performing 
borescope inspections.

Costs of Compliance

    We estimate that this AD affects 40 engines installed on airplanes 
of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
               Action                         Labor cost            Parts cost        product        operators

                                      = $85.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the inspection. We 
estimate that 40 engines will need this replacement.

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

[[Page 51831]]

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to engines, propellers, and 
associated appliances to the Manager, Engine and Propeller Standards 
Branch, Policy and Innovation Division.

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.
