We are adopting a new airworthiness directive (AD) for MD Helicopters Inc. (MDHI) Model 500N and 600N helicopters with certain rotating cone assemblies installed. This AD requires establishing a life limit of 10,000 hours time-in-service (TIS) on these rotating cone assemblies. This AD was prompted by the determination that MDHI created rotating cone assemblies with new dash numbers but incorrectly failed to identify them as life-limited parts. The actions are intended to prevent operation of rotating cone assemblies past their life limits, failure of the rotating cone assemblies, loss of directional control, and subsequent loss of control of the helicopter.

Airworthiness Directives; MD Helicopters Inc.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for MD 
Helicopters Inc. (MDHI) Model 500N and 600N helicopters with certain 
rotating cone assemblies installed. This AD requires establishing a 
life limit of 10,000 hours time-in-service (TIS) on these rotating cone 
assemblies. This AD was prompted by the determination that MDHI created 
rotating cone assemblies with new dash numbers but incorrectly failed 
to identify them as life-limited parts. The actions are intended to 
prevent operation of rotating cone assemblies past their life limits, 
failure of the rotating cone assemblies, loss of directional control, 
and subsequent loss of control of the helicopter.

DATES: This AD is effective February 25, 2016.

SUPPLEMENTARY INFORMATION:

Discussion

    On June 9, 2015, at 80 FR 32508, 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 MDHI Model 500N helicopters 
with a rotating cone assembly part number (P/N) 500N3740-81 installed, 
and Model 600N helicopters with a rotating cone assembly P/N 500N3740-
71 installed. The NPRM proposed to require establishing a life limit of 
10,000 hours TIS on these rotating cone assemblies. Although these 
parts have a life limit of 10,000 hours TIS, they were incorrectly 
omitted from the Airworthiness Limitation Section of the Rotorcraft 
Maintenance Manual. Some of the affected parts were sold as spares, 
while others were installed on new helicopters in production. The 
proposed requirements were intended to prevent operation of rotating 
cone assemblies past their life limits, failure of the rotating cone 
assemblies, loss of directional control, and subsequent loss of control 
of the helicopter.
    Since the NPRM was issued, the FAA Southwest Regional Office has 
relocated. This AD includes the current physical address of the FAA 
Southwest Regional Office.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we received no comments on the NPRM (80 FR 32508, June 9, 
2015).

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

    MDHI issued Service Bulletin SB500N-046 and SB600N-054 (SB) as a 
single bulletin on July 9, 2012. The SB calls for a one-time inspection 
within 100 flight hours to determine the rotating cone assembly's part 
number on MDHI Model 500N and 600N helicopters. The SB then states the 
need to correct the component record for certain rotating cone 
assemblies.
    The SB also specifies determining the rotating cone assembly's 
total service time since new and recording this on the component 
record. MDHI reports that failure to comply with the SB may result in 
an aircraft exceeding the life limit of the rotating cone assembly and 
that this could lead to component failure and loss of directional 
control of the helicopter.

Differences Between This AD and the Service Information

    The SB calls for inspecting the rotating cone assembly to determine 
its P/N. We make no requirement about how to determine the P/N. The 
compliance time for the SB is within 100 flight hours, while this AD 
requires compliance within 1 year or by the next annual inspection, 
whichever comes later.

Costs of Compliance

    We estimate that this AD affects 8 helicopters of U.S. Registry and 
that labor costs average $85 a work hour. We estimate that creating a 
component history card and revising the appropriate records takes 1 
work-hour. No parts are needed for a total cost of $85 per helicopter 
and $680 for the U.S. fleet.

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

[[Page 3320]]

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 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.

comes later:
    (i) Create a component history card or equivalent record for 
each rotating cone assembly, P/N 500N3740-81 and P/N 500N3740-71, 
and record a life limit of 10,000 hours time-in-service (TIS).
    (ii) Revise the Airworthiness Limitations Section of the 
applicable maintenance manual or Instructions for Continued 
Airworthiness by establishing a new retirement life of 10,000 hours 
TIS for each rotating cone assembly, P/N 500N3740-81 and P/N 
500N3740-71, by making pen-and-ink changes or by inserting a copy of
