AGENCY:

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

ACTION:

Final rule.

SUMMARY:

We are adopting a new airworthiness directive (AD) for Pacific Aerospace Limited Model 750XL 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 insufficient clearance between the pitot tubes and the primary support at the flame arrester intersection. We are issuing this AD to require actions to address the unsafe condition on these products.

DATES:

This AD is effective January 10, 2019.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of January 10, 2019.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to Pacific Aerospace Limited Model 750XL airplanes. The NPRM was published in the Federal Register on May 11, 2018 (83 FR 21962). The NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by the Civil Aviation Authority of New Zealand (CAA). The MCAI states:

Pacific Aerospace SB PACSB/XL/094 issue 2, dated 20 March 2018 revised to include inspection information, and DCA/750XL/24A updated to introduce the revised SB.

The [CAA] AD is prompted by a production inspection of installed pitot static plumbing which identified insufficient clearance between the pitot tubes and the primary support at the flame arrestor intersection.

This AD requires inspecting the pitot static tubes for chafing damage, replacing tubing as necessary, installing an additional clamp for pitot static tube support, protecting plumbing with spiralwrap, and ensuring proper clearance between the pitot tubes and the primary support at the flame arrester intersection. The MCAI can be found in the AD docket on the internet at: https://www.regulations.gov/​document?​D=​FAA-2018-0371-0002.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM 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 and changes to clarify the reference to the service information. We have determined that these minor changes:

  • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

We reviewed Pacific Aerospace Service Bulletin PACSB/XL/094, Issue 2, dated March 20, 2018. The service information contains procedures for inspecting the pitot static tubing for chafing, replacing tubing as necessary, installing an additional clamp for pitot static tube support, protecting plumbing with spiralwrap, and ensuring proper clearance between the pitot tubes and the primary support at the flame arrester intersection. 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.

Costs of Compliance

We estimate that this AD will affect 22 products of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the pitot static tubing inspection and installation of support clamps and spiral wrap required by this AD. The average labor rate is $85 per work-hour. Required parts would cost about $25 per product.

Based on these figures, we estimate the cost of the AD on U.S. operators to be $2,420, or $110 per product.

In addition, we estimate that any necessary follow-on actions to replace damaged tubing would take about 1 work-hour and require parts costing $25, for a cost of $110 per product. We have no way of determining the number of products that may need these actions.

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 Start Printed Page 62702Director, 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 appliances to the Director of the Policy and Innovation Division.

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.
