14 CFR Part 39

[Docket No. FAA-2006-24081; Directorate Identifier 2006-CE-15-AD; 
Amendment 39-14623; AD 2006-11-18]
RIN 2120-AA64


Airworthiness Directives; Pacific Aerospace Corporation Ltd. 
Model 750XL Airplanes

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

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Pacific Aerospace Corporation Ltd. Model 750XL airplanes. This AD 
requires you to inspect the condition of the insulation of the wiring 
adjacent to the electrical plugs mounted in the left-hand (LH) and 
right-hand (RH) sides of the forward end of the cockpit center console 
for signs of abrasion and arcing. If you find any evidence of abrasion 
or arcing, this AD requires you to replace the affected wire(s) and 
secure the wires away from the back shells of the electrical plugs. 
This AD results from mandatory continuing airworthiness information 
(MCAI) issued by the airworthiness authority for New Zealand. We are 
issuing this AD to detect and correct damaged wires on the LH and RH 
sides of the forward end of the cockpit center console, which could 
result in short-circuiting of the related wiring. This could lead to 
electrical failure of affected systems and potential fire in the 
cockpit.

DATES: This AD becomes effective on July 14, 2006.
    As of July 14, 2006, the Director of the Federal Register approved 
the incorporation by reference of certain publications listed in the 
regulation.

SUPPLEMENTARY INFORMATION:

Discussion

    On March 20, 2006, we issued a proposal to amend part 39 of the 
Federal Aviation Regulations (14 CFR part 39) to include an AD that 
would apply to certain Pacific Aerospace Corporation Ltd. (Pacific 
Aerospace) Model 750XL airplanes. This proposal was published in the 
Federal Register as a notice of proposed rulemaking (NPRM) on March 27, 
2006 (71 FR 15061). The NPRM proposed to require you to inspect the 
condition of the insulation of the wiring adjacent to the electrical 
plugs mounted in the left-hand (LH) and right-hand (RH) sides of the 
forward end of the cockpit center console for signs of abrasion and 
arcing. If you find any evidence of abrasion or arcing, the NPRM 
proposed to require you to replace the affected wire(s) and secure the 
wires away from the back shells of the electrical plugs.

Comments

    We provided the public the opportunity to participate in developing 
this AD. We received no comments on the proposal or on the 
determination of the cost to the public.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD as proposed 
except for minor editorial corrections. We have determined that these 
minor corrections:
     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.

Costs of Compliance

    We estimate that this AD affects 5 airplanes in the U.S. registry.
    We estimate the following costs to do the inspection:

                                                          Total cost per

----------------------------------------------------------------------------------------------------------------
4 workhours x $80 per hour = $320  Not applicable.....               $320  $320 x 5 = $1,600.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that will be required based on the results of the inspection. We have 
no way of determining the number of airplanes that may need this 
replacement:

------------------------------------------------------------------------
                                                            Total cost
               Labor cost                   Parts cost     per airplane
------------------------------------------------------------------------
28 workhours x $80 per hour = $2,240....            $200          $2,440
------------------------------------------------------------------------

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 AD.

Regulatory Findings

    We have 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 that 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); and
    3. 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 summary of the costs to comply with this AD (and 
other information as included in the Regulatory Evaluation) and placed 
it in the AD Docket. You may get a copy of this summary by sending a 
request to us at the address listed under ADDRESSES. Include ``Docket 
No. FAA-2006-24081; Directorate Identifier 2006-CE-15-AD'' in your 
request.
