Discussion

    The Federal Office of Civil Aviation (FOCA), which is the aviation 
authority for Switzerland, has issued AD HB-2016-001, dated May 17, 
2016 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for PILATUS Aircraft Ltd. Model PC-7 airplanes and was based 
on mandatory continuing airworthiness information 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

    You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
7026.

Related Service Information Under 1 CFR Part 51

    PILATUS Aircraft Ltd. has issued 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 this NPRM.

[[Page 37167]]

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Differences Between This Proposed AD and the Service Information

    The service bulletin requires repetitive inspections by reference 
in a note, which the FAA cannot mandate, so the intent of the note has 
been incorporated into a required action for this proposed AD.

Costs of Compliance

    We estimate that this proposed 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 proposed AD. The 
average labor rate is $85 per work-hour.
    Based on these figures, we estimate the cost of the proposed 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 
$1,615 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 proposed 
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 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 above, 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, 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.
