We are adopting a new airworthiness directive (AD) for certain Pratt & Whitney Canada Corp. (P&WC) PT6B-37A turboshaft engines. This AD requires initial and repetitive inspections until replacement of the No. 10 bearing, and eventual replacement of the No. 9 bearing, both located in the engine reduction gearbox (RGB) assembly. This AD was prompted by reports of incorrect engine torque for PT6B-37A engines. We are issuing this AD to prevent axial migration of the No. 10 bearing in the engine RGB assembly, which could result in engine overtorque, failure of the engine, in-flight shutdown, and loss of the rotorcraft.

Airworthiness Directives; Pratt & Whitney Canada Corp. Turboshaft 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Pratt & Whitney Canada Corp. (P&WC) PT6B-37A turboshaft engines. This 
AD requires initial and repetitive inspections until replacement of the 
No. 10 bearing, and eventual replacement of the No. 9 bearing, both 
located in the engine reduction gearbox (RGB) assembly. This AD was 
prompted by reports of incorrect engine torque for PT6B-37A engines. We 
are issuing this AD to prevent axial migration of the No. 10 bearing in 
the engine RGB assembly, which could result in engine overtorque, 
failure of the engine, in-flight shutdown, and loss of the rotorcraft.

DATES: This AD becomes effective November 18, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 18, 
2015.

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 the specified products. The 
NPRM was published in the Federal Register on June 19, 2015 (80 FR 
35260). The NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    Five incidences of incorrect engine torque indication have been 
reported for PT6B-37A engine installations on AW119MKII helicopters. 
A lower than actual engine torque indication due to a faulty 
indication system, particularly on a helicopter being operated at 
max allowable torque (90 to 110%) range, may result in undetected 
over-torque condition.
    Repeated over-torque conditions that are undetected and 
consequently are not corrected in accordance with conditional 
inspection requirements of original equipment manufacturer (OEM) 
Instructions for Continued Airworthiness (ICAs), may have a negative 
impact on the operational safety of the aircraft. Investigation by 
P&WC has determined the root cause of the subject torque indication 
anomaly to be the axial migration of part number (P/N) 3310433-03 
bearings at the engine torque sensing gear location.

    The axial migration of the No. 10 bearing is caused by non-optimal 
bearing internal clearance. This migration may cause an erroneous 
torque reading, possibly leading to engine overtorque and engine 
failure. We are also requiring replacement of the No. 9 bearing since 
it may also migrate, has the same part number as a No. 10 bearing, and 
could be installed in the same location as a No. 10 bearing.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 35260, June 19, 
2015).

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD as proposed.

Related Service Information Under 1 CFR Part 51

    P&WC has issued Service Bulletin (SB) No. PT6B-72-39095, Revision 
No. 3, dated December 29, 2014. The service information describes 
procedures for inspecting affected bearings. 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 of this final rule.

Other Related Service Information.

    P&WC has also issued SB No. PT6B-72-39092, Revision No. 4, dated 
December 29, 2014. The service information describes procedures for 
removing affected bearings.

Costs of Compliance

    We estimate that this AD affects 83 engines installed on rotocraft 
of U.S. registry. We estimate that it will take about 3 hours per 
engine to comply with this AD. We also estimate that it would take 
about 1 hour per engine to replace the affected bearings. The average 
labor rate is $85 per hour. Required parts cost about $49,800 per 
engine. Based on

[[Page 61718]]

these figures, we estimate the cost of this AD on U.S. operators to be 
$4,161,620.

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

    We determined that 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 this AD:
    (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 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.
