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 certain Honeywell 
International Inc. AS907 series turbofan engines. The NPRM published in 
the Federal Register on August 2, 2017 (82 FR 35914). The NPRM was 
prompted by seven loss-of-thrust-control events attributed to water 
intrusion of the engine ECU with one event having two in-flight 
shutdowns (IFSDs) during the same flight. All loss-of-thrust-control 
events occurred with engines within three years in service. The NPRM 
proposed to require applying sealant to identified areas of the ECU and 
to require inserting a copy of certain airplane operating procedures 
into the applicable flight manuals. 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 final rule. The following presents the comments received on the 
NPRM and the FAA's response to each comment.

Request To Change Differences Between This Proposed AD and the Service 
Information

    Honeywell requested changing the recommended compliance time stated 
in the ``Differences Between This Proposed AD and the Service 
Information'' paragraph. Honeywell stated the compliance time started 
with the issuance of its initial Service Bulletin (SB) AS907-76-9021, 
Revision 0, dated May 13, 2016.
    We partially agree. We agree it would have been appropriate to 
reference the correct compliance time in this discussion within the 
NPRM. We do not agree to revise this final rule because this discussion 
does not exist in the final rule. Further explanation in this final 
rule is not necessary. We did not change this AD.

Request To Remove Interim Action

    Honeywell requested that we remove interim action from this AD. 
Honeywell reasoned that the redesigned ECU, which is equivalent to an 
ECU sealed with external sealant, is outside the scope of this AD.
    We agree since Honeywell does not plan to retrofit or repair older 
ECUs. The older ECUs will be sealed with external sealant for the life 
of the ECU. We removed the Interim Action paragraph from this AD.

Request To Revise Number of Affected Engines

    Honeywell requested that the number of engines affected be changed. 
Honeywell stated the current number of affected engines worldwide is 
680 engines installed in airplanes.
    We partially agree. We agree with Honeywell's current accounting of 
680 affected engines worldwide. We disagree with changing the number of 
affected engines in this AD because our requirement is to estimate the 
number of engines installed on U.S. airplanes. Therefore, we are 
maintaining the estimate made in the NPRM that 477 engines are 
installed on airplanes in the U.S. Registry.

Request To Clarify Applicability

    Honeywell requested that we remove references to ECU Mod Record 
numbers from this AD. Honeywell reasoned that the affected ECUs Mod 
Record numbers are only advanced for production sealed ECUs; therefore, 
ECU Mod Record numbers are not a consistent indication of ECU sealing 
service bulletin compliance.
    We agree. Mod Record numbers are not a good indicator of ECU 
sealing. We revised the applicability of this AD to refer to the engine 
model, serial numbers, and listed ECU part numbers (P/Ns) that are not 
sealed in the areas identified in Figures 1 through 13 of Honeywell SB 
AS907-76-9021, Revision 1, dated April 20, 2017. This change revises 
the method for operators to determine applicability but does not expand 
the scope of this AD since the affected populations of ECUs are the 
same in this final rule as in the NPRM.

Request To Change the Unsafe Condition

    Honeywell requested we revise the unsafe condition statement with 
updated field event information.
    We agree because the unsafe condition in paragraph (e) of the NPRM 
did not include four prior similar loss-of-thrust-control field events 
noted in the Discussion section. We changed the unsafe condition 
paragraph to refer to seven low-time loss-of-thrust control events 
attributed to water intrusion of the engine ECU.

[[Page 9798]]

Request To Add Inspection for Application of Sealant

    Honeywell requested that we revise the compliance section of this 
AD by requiring that applicable ECU P/Ns be inspected for application 
of sealant. The requested change would clarify the method of 
determining whether ECU sealing had been complied with.
    We partially agree. As noted in our response, we have clarified the 
Applicability section of this AD to refer only to affected ECUs that 
are not sealed in the areas identified in Figures 1 through 13 of 
Honeywell SB AS907-76-9021, Revision 1, dated April 20, 2017. We 
therefore, do not need to add an inspection for the application of 
sealant to the compliance section of this AD.

Request To Eliminate Re-Application of ECU Sealant

    Honeywell requested that we remove references to re-application of 
ECU sealant from this final rule. Honeywell commented that this step 
will be accomplished through its continued airworthiness documents.
    We agree that normal maintenance instructions make it unnecessary 
to re-apply the ECU sealant. We revised this final rule by removing the 
references to re-application of the ECU sealant.

Request To Change Compliance

    NetJets questioned whether paragraphs (g)(4), (g)(5), and (g)(6) 
were intended to be subparagraphs of paragraph (g)(3). They justified 
the request by saying that the crew should only be alerted to Cyan 
warning per the AFM (Airplane Flight Manual) Emergency Procedures.
    We agree. We redesignated paragraphs (g)(4), (g)(5), and (g)(6) in 
the NPRM as paragraphs (g)(2)(i), (g)(2)(ii), and (g)(2)(iii) in this 
AD to clarify the intent of the Cyan warning.

Request To Change Credit for Previous Actions

    NetJets requested that Honeywell SB AS907-76-9021, Revision 1, 
dated April 20, 2017, be added to the Credit for Previous Actions 
paragraph. They indicated that an AMOC (alternative method of 
compliance) might be needed to take credit for this previous action if 
Revision 1 of the SB was complied with prior to the effective date of 
the AD.
    We disagree because paragraph (f) already states that compliance is 
necessary unless already done. We did not change this AD.

Revision to Installation Prohibition

    We revised the Installation Prohibition, paragraph (h) of this AD, 
to reflect changes to the applicability and to paragraph designations 
discussed previously.

Miscellaneous Comments

    An individual commenter asked who is responsible for the 
enforcement of this final rule.
    The FAA, Flight Standards Division, is responsible for enforcing 
regulatory violations arising from noncompliance with ADs. We did not 
change this AD.
    An individual commenter suggested that the FAA is not taking into 
account the costs associated with improving the standards of the 
turbofan engines.
    We have taken into account the costs associated with this 
rulemaking as indicated within the Costs of Compliance section of the 
NPRM. We did not change this AD.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this final rule with the changes described previously and minor 
editorial changes. We have determined that these minor changes:
     [Agr]re 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 burden on any operator or increase the scope of this final 
rule.

Related Service Information Under 1 CFR Part 51

    We reviewed Honeywell SB AS907-76-9021, Revision 1, dated April 20, 
2017. The SB describes procedures for applying sealant to identified 
areas of the ECU to prevent water from entering the ECU on AS907 series 
engines. 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 Information

    We also reviewed Honeywell Operating Information Letter (OIL) 
OIAS907-0001R00, dated March 14, 2017. The OIL provides instructions 
for interrogating the onboard Maintenance Data Computer to clear engine 
electronic fault conditions.

Costs of Compliance

    We estimate that this ECU sealing affects 477 engines installed on 
airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we

have included all costs in our cost estimate.

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.
    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

    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.
