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

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:

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.

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.

RIN 2120-AA64
Airworthiness Directives; Honeywell International Inc. Turbofan
Engines
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

[[Page 35915]]
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 https://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-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
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inserting Figure into AFM.......... 2 work-hours x $85 per hour $0 $170.00 $81,090.00
= $170.00.
Application of sealant, on-wing.... 5.5 work-hours x $85 per 50.00 517.50 246,847.50
hour = $467.50.
----------------------------------------------------------------------------------------------------------------
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.
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Fault Check of Maintenance Data Computer... 5 work-hours x $85 per hour = $0 $425.00
$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.
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.
