SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to various airplanes modified
with a certain configuration of the
Garmin GFC 500 Autopilot System
installed per STC No. SA01866WI. The
NPRM published in the Federal
Register on October 10, 2023 (88 FR
69891). The NPRM was prompted by a
report of an un-commanded automatic
pitch trim runaway when the autopilot
was first engaged. In the NPRM, the
FAA proposed to require updating the
applicable Garmin GFC 500 Autopilot
System software for your airplane and
prohibit installing earlier versions of
that software.
The FAA issued a supplemental
notice of proposed rulemaking (SNPRM)
to amend 14 CFR part 39 by adding an
AD that would apply to various
airplanes modified with a certain
configuration of the Garmin GFC 500
Autopilot System installed per STC No.
SA01866WI. The SNPRM published in
the Federal Register on April 17, 2024
(89 FR 27398). The SNPRM was
prompted by comments received on the
NPRM. The SNPRM proposed to revise
the applicability by removing certain
airplane models and adding other
airplane models, revised paragraph (e)
of the proposed AD to clarify that
certain hardware failures affected the
primary pitch servo and added Note 1
to paragraph (g) of the proposed AD.
The FAA is issuing this AD to address
autopilot software that does not
properly handle certain hardware
failures of the primary pitch servo. The
unsafe condition, if not addressed,
could result in un-commanded
automatic pitch trim runaway and loss
of control of the airplane.
Discussion of Final Airworthiness
Directive
Comments
The FAA received one comment from
the National Transportation Safety
Board (NTSB). The NTSB supported the
SNPRM without change.
Conclusion
The FAA reviewed the relevant data,
considered the comment received, and
determined that air safety requires
adopting the AD as proposed.
Accordingly, the FAA is issuing this AD
to address the unsafe condition on these
products. This AD is adopted as
proposed in the SNPRM.
Costs of Compliance
The FAA estimates that this AD
affects 5,900 airplanes of U.S. registry.
The FAA estimates the following
costs to comply with this AD:

Authority for This Rulemaking
Regulatory Findings
The Amendment
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.
The FAA is 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 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) Will not affect intrastate aviation
in Alaska, and
(3) 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.
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:

JM, PW1124G1–JM, PW1124G–JM,
PW1127G1–JM, PW1127G1A–JM,
PW1127G1B–JM, PW1127G–JM,
PW1127GA–JM, PW1129G–JM,
PW1130G–JM, PW1133G–JM, and
PW1133GA–JM engines. The NPRM
published in the Federal Register on
March 25, 2024 (89 FR 20551). The
NPRM was prompted by an incident
involving an Airbus Model A320neo
airplane powered by IAE LLC Model
PW1127G–JM engines that experienced
an IFSD. A manufacturer investigation
determined that the IFSD was caused by
a fractured LPC IBR–1, which resulted
from an aerodynamic excitation. The
most likely cause of the aerodynamic
excitation was a misaligned IGV located
directly upstream of the IBR–1. As a
result, Pratt & Whitney (PW) redesigned
the LPC IGV arm assembly by adding a
spacer to provide additional torque
capability and to prevent a misaligned
vane. PW also redesigned the IBR–1 to
better withstand an aerodynamic
excitation from a misaligned IGV. In the
NPRM, the FAA proposed to require
removal and replacement of affected
LPC key washers and affected LPC IBR–
1 and installation of LPC IGV spacers.
The FAA is issuing this AD to address
the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to various airplanes
modified with a certain configuration of the Garmin GFC 500 Autopilot
System installed per STC No. SA01866WI. The NPRM published in the
Federal Register on October 10, 2023 (88 FR 69891). The NPRM was
prompted by a report of an un-commanded automatic pitch trim runaway
when the autopilot was first engaged. In the NPRM, the FAA proposed to
require updating the applicable Garmin GFC 500 Autopilot System
software for your airplane and prohibit installing earlier versions of
that software.
The FAA issued a supplemental notice of proposed rulemaking (SNPRM)
to amend 14 CFR part 39 by adding an AD that would apply to various
airplanes modified with a certain configuration of the Garmin GFC 500
Autopilot System installed per STC No. SA01866WI. The SNPRM published
in the Federal Register on April 17, 2024 (89 FR 27398). The SNPRM was
prompted by comments received on the NPRM. The SNPRM proposed to revise
the applicability by removing certain airplane models and adding other
airplane models, revised paragraph (e) of the proposed AD to clarify
that certain hardware failures affected the primary pitch servo and
added Note 1 to paragraph (g) of the proposed AD. The FAA is issuing
this AD to address autopilot software that does not properly handle
certain hardware failures of the primary pitch servo. The unsafe
condition, if not addressed, could result in un-commanded automatic
pitch trim runaway and loss of control of the airplane.
Discussion of Final Airworthiness Directive
Comments
The FAA received one comment from the National Transportation
Safety Board (NTSB). The NTSB supported the SNPRM without change.
Conclusion
The FAA reviewed the relevant data, considered the comment
received, and determined that air safety requires adopting the AD as
proposed. Accordingly, the FAA is issuing this AD to address the unsafe
condition on these products. This AD is adopted as proposed in the
SNPRM.
Costs of Compliance
The FAA estimates that this AD affects 5,900 airplanes of U.S.
registry.
The FAA estimates the following costs to comply with this AD:

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.
The FAA is 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
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) Will not affect intrastate aviation in Alaska, and
(3) 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.
