Turbofan Engines Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain Honeywell International Inc. AS907 series turbofan engines. This proposed AD was prompted by two loss-of-thrustcontrol events, and two in-flight shutdowns (IFSDs) of new production, low-time engines attributed to water intrusion of the engine electronic control unit (ECU). This proposed AD would require applying sealant to identified areas of the ECU and requires inserting a copy of certain airplane operating procedures into the applicable flight manuals. We are proposing this SUMMARY: PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 AD to correct the unsafe condition on these products. DATES: We must receive comments on this proposed AD by September 18, 2017.

SUPPLEMENTARY INFORMATION: Comments Invited We invite you to send any written relevant data, views, or arguments about this NPRM. Send your comments to an address listed under the ADDRESSES E:\FR\FM\02AUP1.SGM 02AUP1 Federal Register / Vol. 82, No. 147 / Wednesday, August 2, 2017 / Proposed Rules section. Include ‘‘Docket No. FAA– 2017–0020; Directorate Identifier 2016– NE–33 AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this NPRM. We will consider all comments received by the closing date and may amend this NPRM because of those comments. We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this NPRM. Discussion We received reports of two loss-ofthrust-control events and two IFSDs of new production, low-time AS907–2–1A engines, attributed to water intrusion into the ECU at the ECU cover-to-body splitline, cover screws and cavities, leading to internal board electrical faults. Similar events have occurred on AS907–1–1A engines when rainwater dripped through the ECU and T2 engine access panels at 10 and 2 o’clock locations onto the ECU and harnesses while the airplane was on the ground. This proposed AD would require application of sealant to identified areas of the ECU and requires inserting a copy of certain airplane operating procedures into the applicable flight manuals. These procedures describe interim actions for not dispatching the airplane under certain engine electronic fault conditions. This condition, if not corrected, could result in dual engine power loss, loss of thrust control, and damage to the engine and airplane. FAA’s Determination Related Service Information Under 1 CFR Part 51 35915 Proposed AD Requirements We reviewed Honeywell Service Bulletin (SB); SB AS907–76–9021, Revision 1, dated April 20, 2017; Operating Information Letter (OIL) OIAS907–0001R00, dated March 14, 2017; Component Maintenance Manual (CMM) 2119576, Temporary Revision (TR) No. 76–1, Section 76–10–15, dated September 6, 2016; and CMM 2119576, TR No. 76–1, Section 76–10–29, dated August 2, 2016. In combination, the SB and TRs describe procedures for applying sealant to identified areas of the ECU to prevent water from entering the ECU on AS907 series engines. The OIL provides instructions for interrogating the onboard Maintenance Data Computer to clear engine electronic fault conditions. 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. 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 other products of the same type design. This proposed AD would require applying sealant to identified areas of the ECU. Differences Between This Proposed AD and the Service Information Honeywell SB AS907–76–9021, Revision 1, dated April 20, 2017 recommends complying after 400 engine operating hours, not to exceed 18 months from the date of issuance of the SB. This NPRM proposes complying within 200 engine operating hours or 9 months after the effective date of the AD, whichever occurs first. Interim Action We consider this proposed AD interim action. Honeywell is developing design changes that will eliminate the need to apply sealant to the ECU. 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 proposed AD: ESTIMATED COSTS Action Labor cost Inserting Figure into AFM ............................... Application of sealant, on-wing ....................... 2 work-hours × $85 per hour = $170.00 ........ 5.5 work-hours × $85 per hour = $467.50 ..... We estimate the following costs to do any necessary fault checks of the Parts cost Maintenance Data Computer (MDC)/ Onboard Messaging System (OMS). We $0 50.00 Cost per product Cost on U.S. operators $170.00 517.50 $81,090.00 246,847.50 estimate that 20 engines will need this fault check. ON-CONDITION COSTS Labor cost Fault Check of Maintenance Data Computer ............... jstallworth on DSKBBY8HB2PROD with PROPOSALS Action 5 work-hours × $85 per hour = $425.00 ...................... 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. VerDate Sep<11>2014 15:16 Aug 01, 2017 Jkt 241001 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, PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 Cost per product Parts cost $0 $425.00 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 E:\FR\FM\02AUP1.SGM 02AUP1 Federal Register / Vol. 82, No. 147 / Wednesday, August 2, 2017 / Proposed Rules products identified in this rulemaking action. Regulatory Findings ■ We 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 this 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, 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.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Honeywell International Inc. AS907 series turbofan engines. 
This proposed AD was prompted by two loss-of-thrust-control events, and 
two in-flight shutdowns (IFSDs) of new production, low-time engines 
attributed to water intrusion of the engine electronic control unit 
(ECU). This proposed AD would require applying sealant to identified 
areas of the ECU and requires inserting a copy of certain airplane 
operating procedures into the applicable flight manuals. We are 
proposing this AD to correct the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by September 18, 
2017.

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

Discussion

    We received reports of two loss-of-thrust-control events and two 
IFSDs of new production, low-time AS907-2-1A engines, attributed to 
water intrusion into the ECU at the ECU cover-to-body splitline, cover 
screws and cavities, leading to internal board electrical faults. 
Similar events have occurred on AS907-1-1A engines when rainwater 
dripped through the ECU and T2 engine access panels at 10 and 2 o'clock 
locations onto the ECU and harnesses while the airplane was on the 
ground. This proposed AD would require application of sealant to 
identified areas of the ECU and requires inserting a copy of certain 
airplane operating procedures into the applicable flight manuals. These 
procedures describe interim actions for not dispatching the airplane 
under certain engine electronic fault conditions. This condition, if 
not corrected, could result in dual engine power loss, loss of thrust 
control, and damage to the engine and airplane.

Related Service Information Under 1 CFR Part 51

    We reviewed Honeywell Service Bulletin (SB); SB AS907-76-9021, 
Revision 1, dated April 20, 2017; Operating Information Letter (OIL) 
OIAS907-0001R00, dated March 14, 2017; Component Maintenance Manual 
(CMM) 2119576, Temporary Revision (TR) No. 76-1, Section 76-10-15, 
dated September 6, 2016; and CMM 2119576, TR No. 76-1, Section 76-10-
29, dated August 2, 2016.
    In combination, the SB and TRs describe procedures for applying 
sealant to identified areas of the ECU to prevent water from entering 
the ECU on AS907 series engines. The OIL provides instructions for 
interrogating the onboard Maintenance Data Computer to clear engine 
electronic fault conditions. 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.

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 other products of the same type design.

Proposed AD Requirements

    This proposed AD would require applying sealant to identified areas 
of the ECU.

Differences Between This Proposed AD and the Service Information

    Honeywell SB AS907-76-9021, Revision 1, dated April 20, 2017 
recommends complying after 400 engine operating hours, not to exceed 18 
months from the date of issuance of the SB. This NPRM proposes 
complying within 200 engine operating hours or 9 months after the 
effective date of the AD, whichever occurs first.

Interim Action

    We consider this proposed AD interim action. Honeywell is 
developing design changes that will eliminate the need to apply sealant 
to the ECU.

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 proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary fault checks of 
the Maintenance Data Computer (MDC)/Onboard Messaging System (OMS). We 
estimate that 20 engines will need this fault check.

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

    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

[[Page 35916]]

products identified in this rulemaking action.

Regulatory Findings

    We 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 this 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, 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.
