Airworthiness Directives; PILATUS Aircraft Ltd. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for PILATUS 
Aircraft Ltd. Model PC-7 airplanes. This AD results from mandatory 
continuing airworthiness information (MCAI) issued by an aviation 
authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as stress corrosion cracking on the main frame on frame 11 
left and right fittings. We are issuing this AD to require actions to 
address the unsafe condition on these products.

DATES: This AD is effective September 30, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of September 30, 
2016.

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 PILATUS Aircraft Ltd. Model 
PC-7 airplanes. The NPRM was published in the Federal Register on June 
9, 2016 (81 FR 37166). The NPRM proposed to correct an unsafe condition 
for the specified products and was based on mandatory continuing 
airworthiness information (MCAI) originated by an aviation authority of 
another country. The MCAI states:

    This Airworthiness Directive (AD) is prompted due to a report of 
Stress Corrosion Cracking (SCC) on the Main Frame on Frame (FR) 11 
left fitting Part Number (P/N) 112.35.07.489 and right fitting P/N 
112.35.07.490.
    Such a condition, if left uncorrected, could lead to potential 
loss of the horizontal stabilizer.
    In order to correct and control the situation, this AD requires 
a one-time check to identify the material specification and inspect 
the affected areas of the airframe that are made of aluminum alloy 
AA2024-T351. Any structural parts of the aircraft structure found to 
be cracked must be reported to Pilatus prior to further flight.

The MCAI can be found in the AD docket on the Internet at: https://www.regulations.gov/document?D=FAA-2016-7026-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (81 FR 37166, June 9, 
2016) or on the determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting the AD as proposed except for 
minor editorial changes. We have determined that these minor changes:

     Are consistent with the intent that was proposed in the 
NPRM (81 FR 37166, June 9, 2016) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than 
was already proposed in the NPRM (81 FR 37166, June 9, 2016).

Related Service Information Under 1 CFR Part 51

    We reviewed PILATUS Aircraft Ltd. PC-7 Service Bulletin No: 53-013; 
and PILATUS Aircraft Ltd. PC-7 Service Bulletin No: 53-014, both dated 
February 25, 2016. PILATUS Aircraft Ltd. PC-7 Service Bulletin No: 53-
013, dated February 25, 2016, describes procedures for initial and 
repetitive inspection of the main frame FR11 left and right fittings 
for stress corrosion cracking; and PILATUS Aircraft Ltd. PC-7 Service 
Bulletin No: 53-014, dated February 25, 2016, describes procedures for 
replacement of the main frame FR11 left and right fittings when 
necessary. 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 the AD.

Costs of Compliance

    We estimate that this AD will affect 19 products of U.S. registry. 
We also estimate that it would take about 3 work-hours per product to 
check the material specification of the fittings and 11 work-hours per 
product to inspect the 2014-T351 fittings as required in order to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour.
    Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $17,765, or $935 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 19 work-hours and require parts costing $5,000 for a cost of 
$6,615 per product. We have no way of determining the number of 
products that may need these actions.
    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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

[[Page 58812]]

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, 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.
