RIN 2120-AA64
Airworthiness Directives; Pacific Aerospace Corporation Ltd.
750XL Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) that
supersedes AD 2005-26-53, which applies to certain Pacific Aerospace
Corporation Ltd. (PAC) 750XL airplanes. AD 2005-26-53 currently
requires you to insert text into the Limitations Section of the
Airplane Flight Manual (AFM) that reduces the maximum takeoff weight
from 7,500 pounds to 7,125 pounds. This AD results from mandatory
continuing airworthiness information (MCAI) issued by the airworthiness
authority for New Zealand and the FAA's decision that the actions
correct an unsafe condition. Consequently, this AD would require you to
remove rivets that have not been fully age hardened and replace them
[[Page 35510]]
with bolts, washers, and nuts in specific locations where reduction in
rivet strength affects overall structural capability. This AD retains
the actions of the previous AD until the rivets are replaced with the
bolts, washers, and nuts. We are issuing this AD so that wing ultimate
load requirements are met. If wing ultimate load requirements are not
met, wing failure could result with consequent loss of control of the
airplane.
DATES: This AD becomes effective on July 31, 2006.
As of July 31, 2006, the Director of the Federal Register approved
the incorporation by reference of certain publications listed in the
regulation.

SUPPLEMENTARY INFORMATION:
Discussion
On March 3, 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. (PAC) 750XL
airplanes. This proposal was published in the Federal Register as a
notice of proposed rulemaking (NPRM) on March 10, 2006 (71 FR 12305).
The NPRM proposed to supersede AD 2005-26-53, Amendment 39-14451 (71 FR
2453, January 17, 2006), and require you to remove rivets that have not
been fully age hardened and replace them with bolts, washers, and nuts
in specific locations where reduction in rivet strength affects overall
structural capability. The proposed AD would retain the airplane weight
AFM Limitations requirement of AD 2005-26-53 until the rivets are
replaced with the bolts, washers, and nuts.
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 7 airplanes in the U.S. registry.
We estimate the following costs to do the replacement:
----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
32 work-hours x $80 per hour = $2,560........................ $519 $3,079 $21,553
----------------------------------------------------------------------------------------------------------------
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-2006-23579; Directorate Identifier 2006-CE-02-AD'' in your
request.

2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD)
2005-26-53, Amendment 39-14451 (71 FR 2453, January 17, 2006), and by
adding the following new airworthiness directive:
2006-13-05 Pacific Aerospace Corporation Ltd.: Amendment 39-14658;
Docket No. FAA-2006-23579; Directorate Identifier 2006-CE-02-AD.
Effective Date
(a) This AD becomes effective on July 31, 2006.
[[Page 35511]]
Affected ADs
(b) This AD supersedes AD 2005-26-53; Amendment 39-14451.
Applicability
(c) This AD affects Model 750XL airplanes, serial numbers 101,
102, 104 through 120, and 125, that are certificated in any

Unsafe Condition
(d) This AD is the result of some critical rivets on the wing

locations where reduction in rivet strength reduces wing strength.
The actions specified in this AD are intended to ensure wing
ultimate load requirements are met. If wing ultimate load
requirements are not met, wing failure could result with consequent
loss of control of the airplane.
