We are adopting a new
airworthiness directive (AD) for
Sikorsky Aircraft Corporation (type
certificate previously held by Schweizer
Aircraft Corporation) (Sikorsky) Model
269D and Model 269D Configuration A
helicopters. This AD requires reducing
the life limit of the ring gear carrier
assembly. This AD was prompted by
cracks in the ring gear carrier assembly.
The actions are intended to reduce the
life of the ring gear carrier assembly to
prevent failure of the main rotor
transmission, loss of engine power to
the main rotor, and subsequent loss of
control of the helicopter.

SUPPLEMENTARY INFORMATION:
Discussion
On December 15, 2014, at 79 FR
74037, the Federal Register published
our notice of proposed rulemaking
(NPRM), which proposed to amend 14
CFR part 39 by adding an AD that
would apply to Sikorsky Model 269D
and Model 269D Configuration A
helicopters with a certain partnumbered ring carrier assembly
installed. The NPRM proposed to
require reducing the life limit of the ring
carrier assembly from 6,000 hours timein-service (TIS) to 5,000 hours TIS by
revising the Airworthiness Limitations
Section of the applicable maintenance
manual and by removing from service
any ring carrier assembly that exceeded
the new life limit. The NPRM was
prompted by the discovery of a crack in
the ring gear carrier assembly, which
extended around the entire
circumference of the flange and
intersected some of the bolt holes but
did not propagate ‘‘bolt hole to bolt
hole.’’ A metallurgical evaluation
determined that fretting caused multiple
origin fatigue cracking on the ring gear
carrier assembly. The proposed
requirements were intended to reduce
the life of the ring gear carrier assembly
to prevent failure of the main rotor
transmission, loss of engine power to
the main rotor, and subsequent loss of
control of the helicopter.
Comments
We gave the public the opportunity to
participate in developing this AD, but
we did not receive any comments on the
NPRM (79 FR 74037, December 15,
2014).
FAA’s Determination
We have reviewed the relevant
information and determined that an
unsafe condition exists and is likely to
exist or develop on other products of
these same type designs and that air
safety and the public interest require
adopting the AD requirements as
proposed.
Related Service Information
Sikorsky issued 269D Helicopter Alert
Service Bulletin No. ASB DB–040A,
Revision A, dated December 4, 2012, to
implement a reduction in service life of
the ring gear carrier assembly, part
number 269A5194, from 6,000 flight
hours to 5,000 flight hours.

Federal Register / Vol. 80, No. 110 / Tuesday, June 9, 2015 / Rules and Regulations
Costs of Compliance
We estimate that this AD will affect
16 helicopters of U.S. Registry.
We estimate that operators may incur
the following costs in order to comply
with this AD. We estimate a minimal
cost to change the life limit of the ring
gear. If required, we estimate it would
take 27.5 hours to replace a ring gear
carrier assembly at $85 per work hour.
Required parts would cost $7,591 for a
total of $9,929 per helicopter.
Authority for This Rulemaking
tkelley on DSK3SPTVN1PROD with RULES
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 to the extent that it justifies
making a regulatory distinction; 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.
We prepared an economic evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.

Adoption of the Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
PART 39—AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
■
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,

‘‘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.

SUPPLEMENTARY INFORMATION:
Discussion
On December 15, 2014, at 79 FR 74037, the Federal Register
published our notice of proposed rulemaking (NPRM), which proposed to
amend 14 CFR part 39 by adding an AD that would apply to Sikorsky Model
269D and Model 269D Configuration A helicopters with a certain part-
numbered ring carrier assembly installed. The NPRM proposed to require
reducing the life limit of the ring carrier assembly from 6,000 hours
time-in-service (TIS) to 5,000 hours TIS by revising the Airworthiness
Limitations Section of the applicable maintenance manual and by
removing from service any ring carrier assembly that exceeded the new
life limit. The NPRM was prompted by the discovery of a crack in the
ring gear carrier assembly, which extended around the entire
circumference of the flange and intersected some of the bolt holes but
did not propagate ``bolt hole to bolt hole.'' A metallurgical
evaluation determined that fretting caused multiple origin fatigue
cracking on the ring gear carrier assembly. The proposed requirements
were intended to reduce the life of the ring gear carrier assembly to
prevent failure of the main rotor transmission, loss of engine power to
the main rotor, and subsequent loss of control of the helicopter.
Comments
We gave the public the opportunity to participate in developing
this AD, but we did not receive any comments on the NPRM (79 FR 74037,
December 15, 2014).
FAA's Determination
We have reviewed the relevant information and determined that an
unsafe condition exists and is likely to exist or develop on other
products of these same type designs and that air safety and the public
interest require adopting the AD requirements as proposed.
Related Service Information
Sikorsky issued 269D Helicopter Alert Service Bulletin No. ASB DB-
040A, Revision A, dated December 4, 2012, to implement a reduction in
service life of the ring gear carrier assembly, part number 269A5194,
from 6,000 flight hours to 5,000 flight hours.
[[Page 32461]]
Costs of Compliance
We estimate that this AD will affect 16 helicopters of U.S.
Registry.
We estimate that operators may incur the following costs in order
to comply with this AD. We estimate a minimal cost to change the life
limit of the ring gear. If required, we estimate it would take 27.5
hours to replace a ring gear carrier assembly at $85 per work hour.
Required parts would cost $7,591 for a total of $9,929 per helicopter.
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.
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
