We propose to adopt a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters. This proposed AD would require removing from service the tail gearbox center housing (housing) when it has 12,200 or more hours time-in-service (TIS). This proposed AD is prompted by fatigue analysis conducted by Sikorsky that determined the housing required a retirement life. The proposed actions are intended to prevent a crack in the housing, which could lead to loss of tail rotor drive and loss of helicopter control.

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for

Sikorsky that determined the housing required a retirement life. The 
proposed actions are intended to prevent a crack in the housing, which 
could lead to loss of tail rotor drive and loss of helicopter control.

we receive.

Discussion

    We propose to adopt a new AD for Sikorsky Model S-92A helicopters 
with a housing, part number (P/N) 92358-06107-043, installed. This 
proposed AD would establish a life limit of 12,200 hours TIS for the 
housing by requiring that the housing be removed from service when it 
reaches 12,200 hours TIS. This proposed AD is prompted by an analysis 
conducted by Sikorsky on the Model S-92A helicopter for a gross weight 
increase that revealed higher than expected loads. The housing 
currently has no life limit. Sikorsky's analysis, which used updated 
load conditions and updated fatigue analysis software, determined 
housings that remain in service beyond 12,200 hours TIS present an 
unacceptable risk of cracking. This condition could result in loss of 
tail rotor drive and loss of helicopter control.

FAA's Determination

    We are proposing this AD because we evaluated all known relevant 
information and determined that an unsafe condition exists and is 
likely to exist or develop on other products of these same type 
designs.

Related Service Information

    We reviewed Sikorsky S-92 Maintenance Manual 4-00-00, Temporary 
Revision No. 4-49, dated April 10, 2015, which establishes a 
replacement interval of 12,200 hours for housing, P/N 92358-06107-043.

Proposed AD Requirements

    This proposed AD would require, before further flight, removing 
from service any tail gearbox housing, P/N 92358-06107-043, that has 
12,200 or more hours TIS.

Costs of Compliance

    We estimate that this proposed AD would affect 80 helicopters of 
U.S. Registry and that labor costs average $85 per work hour. Based on 
these estimates, we expect the following costs. Replacing the housing 
would require 24 work-hours, and parts would cost $58,000 for a total 
cost of $60,040 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

    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, 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 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 proposed AD and placed it in the AD docket.
