    AGENCY:

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

    ACTION:

    Notice of proposed rulemaking (NPRM).

    SUMMARY:

    We propose to supersede Airworthiness Directive (AD) 2015-23-03 for Pacific Aerospace Limited Model 750XL airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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 fatigue cracks on the fin forward pickup plates. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

    Discussion

    We issued AD 2015-23-03, Amendment 39-18319 (80 FR 69569; November 10, 2015) (“AD 2015-23-03”). That AD required actions intended to address an unsafe condition on Pacific Aerospace Limited Model 750XL airplanes and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country.

    Since we issued AD 2015-23-03, a new part number (P/N) hi-lok fastener has become available due to limited availability of the original hi-lok P/N.

    The Civil Aviation Authority of New Zealand (CAA), has issued DCA/750XL/18B, dated February 28, 2018 (referred to after this as “the MCAI”), to correct an unsafe condition for Pacific Aerospace Limited Model 750XL airplanes. The MCAI states:

    This (CAA) AD revised to introduce Pacific Aerospace Limited Mandatory Service Bulletin (MSB) PACSB/XL/068 issue 6, dated 8 January 2018. The changes to the SB are limited to minor editorial changes, and the addition of alternate P/N hi-lok fasteners due to limited availability of the original P/N. There are no changes to the AD applicability or the requirements.

    You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-0422.

    Related Service Information Under 1 CFR Part 51

    Pacific Aerospace Limited has issued Pacific Aerospace Service Bulletin PACSB/XL/068, Issue 6, dated January 8, 2018. The service information describes procedures for reducing the torque setting for the fin forward pickup bolt. The service bulletin also introduces a new, improved replacement fin forward pickup plate, part number (P/N) 11-0375-1, to replace P/N 11-10281-1. 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.

    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 Start Printed Page 28172in 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.

    Costs of Compliance

    We estimate that this AD will affect 22 products of U.S. registry. We also estimate that it will take about 22 work-hours per product to comply with all the requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $1,692 per product.

    Based on these figures, we estimate the cost of this AD on U.S. operators to be $78,364, or $3,562 per product.

    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.

    This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to small airplanes, gliders, balloons, airships, domestic business jet transport airplanes, and associated products to the Director of the Policy and Innovation Division.

    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.

    (1) Within the next 150 hours time-in-service (TIS) after the effective date of this AD, reduce the fin forward pickup bolt torque following the procedures in section 1.D., paragraphs A. 1) and A. 2) of the PLANNING INFORMATION in Pacific Aerospace Limited Mandatory Service Bulletin PACSB/XL/068, Issue 6, dated January 8, 2018.

    (2) At or before reaching 2,000 hours total time-in-service (TTIS) or within the next 150 hours TIS after the effective date of this AD, whichever occurs later, and repetitively thereafter at intervals not to exceed 600 hours TIS or 12 months, whichever occurs first, do a detailed visual inspection and liquid penetrant inspection of the fin forward pickup plates for any evidence of cracking. Do the inspections following the procedures in sections 2.A. and 2.B. of the ACCOMPLISHMENT INSTRUCTIONS in Pacific Aerospace Limited Mandatory Service Bulletin PACSB/XL/068, Issue 6, dated January 8, 2018.

    (3) If cracks are found in either of the forward pickup plates during any inspection required in paragraph (f)(2) of this AD, before further flight, replace both fin forward pickup plates with new fin forward pickup plates, part number (P/N) 11-03375-1. Do the replacement following the procedures in section 2.C. of the ACCOMPLISHMENT INSTRUCTIONS in Pacific Aerospace Limited Mandatory Service Bulletin PACSB/XL/068, Issue 6, dated January 8, 2018. This replacement terminates the repetitive inspections required in paragraph (f)(2) of this AD.

    (4) If no cracks are found during any inspection required in paragraph (f)(2) of this AD, at or before reaching 6,000 hours TTIS or within the next 600 hours TIS after the effective date of this AD, whichever occurs later, replace both fin forward pickup plates, P/N 11-10281-1, with P/N 11-03375-1. Do the replacement following the procedures in section 2.C or 2.D. of the ACCOMPLISHMENT INSTRUCTIONS in Pacific Aerospace Limited Mandatory Service Bulletin PACSB/XL/068, Issue 6, dated January 8, 2018. This replacement terminates the repetitive inspections required in paragraph (f)(2) of this AD.
