Start Preamble

AGENCY:

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

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) 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 non-compliant insulation lagging on the refrigerant hoses of the air-conditioning system. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

DATES:

We must receive comments on this proposed AD by December 7, 2018.

ADDRESSES:

You may send comments by any of the following methods:

  • Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.

Discussion

The Civil Aviation Authority (CAA), which is the aviation authority for New Zealand, has issued AD DCA/750XL/29, dated July 5, 2018 (referred to after this as “the MCAI”), to correct an unsafe condition for Pacific Aerospace Limited Model 750XL airplanes. The MCAI states:

The insulation lagging provided by the air-conditioning supplier has been found to be non-compliant and may cause large amounts of smoke in the cabin in the event of a fire. DCA/750XL/29 issued to mandate the instructions in Pacific Aerospace Mandatory Service Bulletin (MSB) PACSB/XL/086 issue 2, dated 6 April 2018, or later approved revision to correct non-compliant insulation lagging on the refrigerant hoses of the air-conditioning system.

You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-0895.

Related Service Information Under 1 CFR Part 51

Pacific Aerospace Limited has issued Pacific Aerospace Service Bulletin PACSB/XL/086, Issue 2, dated April 6, 2018. The service information provides instructions for replacing the noncompliant insulation lagging with compliant materials. 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 This 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.

Costs of Compliance

We estimate that this proposed AD will affect 22 products of U.S. registry. We also estimate that it would take about 32 work-hours per product to comply with the basic requirements of this proposed AD. The average labor Start Printed Page 53408rate is $85 per work-hour. Required parts would cost about $500 per product.

Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $70,840, or $3,220 per product.

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.

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 appliances 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.

2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD):

End Amendment Part

Pacific Aerospace Limited: Docket No. FAA-2018-0895; Product Identifier 2018-CE-037-AD.

(a) Comments Due Date

We must receive comments by December 7, 2018.

(b) Affected ADs

None.

(c) Applicability

This AD applies to Pacific Aerospace Limited Model 750XL airplanes, serial numbers (S/N) up to and including S/N 205, S/N 207, and S/N 208, certificated in any category, with an air-conditioning modification PAC/XL/0409 or PAC/XL/0618 installed.

(d) Subject

Air Transport Association of America (ATA) Code 21: Air Conditioning.

(e) Reason

This AD was prompted by 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 non-compliant insulation lagging on the refrigerant hoses of the air-conditioning system. We are issuing this AD to replace non-compliant insulation lagging on the refrigerant hoses of the air-conditioning system, which could lead to smoke in the cabin if a fire occurred.

(f) Actions and Compliance

Unless already done, within 150 hours time-in-service after the effective date of this AD, remove existing refrigeration hose lagging, install fire sleeve lagging, and install aluminum tape at the wing spar by following the Accomplishment Instructions in Pacific Aerospace Service Bulletin PACSB/XL/086, Issue 2, dated April 6, 2018.

(g) Other FAA AD Provisions

The following provisions also apply to this AD:

(1) Alternative Methods of Compliance (AMOCs): The Manager, Small Airplane Standards Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Mike Kiesov, Aerospace Engineer, FAA, Small Airplane Standards Branch, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4144; fax: (816) 329-4090; email: mike.kiesov@faa.gov. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO.

(2) Contacting the Manufacturer: For any requirement in this AD to obtain corrective actions from a manufacturer, the action must instead be accomplished using a method approved by the Manager, Small Airplane Standards Branch, FAA; or the Civil Aviation Authority of New Zealand (CAA).
