Airworthiness Directives; Pacific Aerospace Limited Model 750XL Airplanes
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 the products listed above. 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:
DCA/750XL/3A is prompted by a report from the manufacturer of the possibility that wiring loom protective sleeving is not fitted to aircraft S/N 107 through to 134. AD applicability revised to include aircraft up to S/N 134.
To prevent fretting damage to the wiring loom that may lead to arcing in proximity to the fuel vent lines and the possibility of fire * * *
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
DATES: We must receive comments on this proposed AD by February 19, 2008.

Discussion
The Civil Aviation Authority (CAA), which is the airworthiness authority for New Zealand, has issued AD DCA/750XL/3A, dated November 28, 2007 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states:
DCA/750XL/3A is prompted by a report from the manufacturer of the possibility that wiring loom protective sleeving is not fitted to aircraft S/N 107 through to 134. AD applicability revised to include aircraft up to S/N 134.
To prevent fretting damage to the wiring loom that may lead to arcing in proximity to the fuel vent lines and the possibility of fire, inspect the main wiring loom on the right hand side of the aircraft adjacent to the frames at station 114.34'' and 118.84'', per PACSB/XL/009 issue 2, to ensure that two pieces of protective sleeving are fitted.
The effectivity of the service information is serial number (S/N) 102 through 106. The MCAI expanded the applicability to S/N 102 through 134.

You may obtain further information by examining the MCAI in the AD docket.
Relevant Service Information
Pacific Aerospace Corporation Limited has issued Mandatory Service Bulletin PACSB/XL/009, issue 2, revised July 23, 2004. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.
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 MCAI or Service Information
We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information.
We might also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a Note within the proposed AD.
Costs of Compliance
Based on the service information, we estimate that this proposed AD would affect about 7 products of U.S. registry. We also estimate that it would take about 0.5 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Required parts would cost about $30 per product.
Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $490, or $70 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.
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:
-
Is not a ``significant regulatory action'' under Executive Order 12866;
-
Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and
-
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.
We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.
List of Subjects in 14 CFR Part 39

The Proposed Amendment
Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
-
The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
-
The FAA amends Sec. 39.13 by adding the following new AD:
Pacific Aerospace Limited: Docket No. FAA-2008-0034; Directorate Identifier 2007-CE-097-AD.
Comments Due Date
(a) We must receive comments by February 19, 2008.
Affected ADs
(b) or None.
Applicability
(c) This AD applies to Model 750XL airplanes, serial numbers 102 through 134, certificated in any category.
Note 1: The applicability of this AD takes precedence over Pacific Aerospace Corporation Limited Mandatory Service Bulletin PACSB/XL/009, issue 2, revised July 23, 2004.
Subject
(d) Air Transport Association of America (ATA) Code 39: Electrical Wiring.
Reason
(e) The mandatory continuing airworthiness information (MCAI) states:
DCA/750XL/3A is prompted by a report from the manufacturer of the possibility that wiring loom protective sleeving is not fitted to aircraft S/N 107 through to 134. AD applicability revised to include aircraft up to S/N 134.
To prevent fretting damage to the wiring loom that may lead to arcing in proximity to the fuel vent lines and the possibility of fire, inspect the main wiring loom on the right hand side of the aircraft adjacent to the frames at station 114.34'' and 118.84'', per PACSB/XL/009, issue 2, to ensure that two pieces of protective sleeving are fitted.
The effectivity of the service information is serial number (S/ N) 102 through 106. The MCAI expanded the applicability to S/N 102 through 134.
Actions and Compliance
(f) Unless already done, do the following actions:
(1) Within the next 100 hours time-in-service (TIS) after the effective date of this AD, inspect the main wiring loom on the right hand side of the aircraft adjacent to the frames at station 114.34'' and 118.84'' to ensure there are two pieces of protective sleeving installed following Pacific Aerospace Corporation Limited Mandatory Service Bulletin PACSB/XL/009, issue 2, revised July 23, 2004.
(2) If the protective sleeves are missing, install protective sleeves following Pacific Aerospace Corporation Mandatory Service Bulletin PACSB/XL/009, issue 2, revised July 23, 2004.
FAA AD Differences
Note 2: This AD differs from the MCAI and/or service information as follows: No differences.
