Airworthiness Directives; Pilatus Aircraft Limited PC-12 and PC-
12/45 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) 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 executive seats equipped with pedestal legs that were
produced using a material that deviates from the approved design data.
The proposed AD would require actions that are intended to address the
unsafe condition described in the MCAI.

SUPPLEMENTARY INFORMATION:
Streamlined Issuance of AD
The FAA is implementing a new process for streamlining the issuance
of ADs related to MCAI. The streamlined process will allow us to adopt
MCAI safety requirements in a more efficient manner and will reduce
safety risks to the public. This process continues to follow all FAA AD
issuance processes to meet legal, economic, Administrative Procedure
Act, and Federal Register requirements. We also continue to meet our
technical decision-making responsibilities to identify and correct
unsafe conditions on U.S.-certificated products.
This proposed AD references the MCAI and related service
information that we considered in forming the engineering basis to
correct the unsafe condition. The proposed AD contains text copied from
the MCAI and for this reason might not follow our plain language
principles.
Comments Invited
We invite you to send any written relevant data, views, or
arguments about this proposed AD. Send your comments to an address
listed under the ADDRESSES section. Include ``Docket No. FAA-2006-
26371; Directorate Identifier 2006-CE-70-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of this proposed AD. We
will consider all comments received by the closing date and may amend
this proposed AD because of those comments.
We will post all comments we receive, without change, to http://dms.dot.gov
, including any personal information you provide. We will
also post a report summarizing each substantive verbal contact we
receive about this proposed AD.
Discussion
The Federal Office of Civil Aviation (FOCA), which is the aviation
authority for Switzerland, has issued FOCA AD HB-2006-444, dated
November 7, 2006 (referred to after this as ``the MCAI''), to correct
an unsafe condition for the specified products. The MCAI states that
executive seats equipped with pedestal legs were produced using a
material that deviates from the approved design data. As a consequence
the pedestal legs may not perform as intended under emergency landing
conditions. In order to correct and control the situation, this AD
requires a one time inspection to identify the Vendor Part Number (VPN)
of the pedestal legs and the Serial Number (S/N) of the executive seat
and the replacement of the pedestal legs if necessary. You may obtain
further information by examining the MCAI in the AD docket.
Relevant Service Information
Pilatus Aircraft Limited has issued Service Bulletin No.: 25-032,
dated October 2, 2006, and DeCrane Aircraft Seating Company, Inc. has
issued Mandatory Service Bulletin SB05147 Revision B, dated June 26,
2006. 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
[[Page 71498]]
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
described in a separate paragraph of the proposed AD. These
requirements, if ultimately adopted, will take precedence over the
actions copied from the MCAI.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 394 products of U.S. registry. We also estimate that
it would take about 0.5 work-hours per product to comply with the
inspection requirement of the proposed AD. In addition, we estimate
this proposed AD would affect about 59 seats and take about 1 work-hour
per seat to comply with the parts replacement requirement of the
proposed AD. The average labor rate is $80 per work-hour. Where the
service information lists required parts costs that are covered under
warranty, we have assumed that there will be no charge for these costs.
As we do not control warranty coverage for affected parties, some
parties may incur costs higher than estimated here. Based on these
figures, we estimate the cost of the proposed AD on U.S. operators to
be $15,760, or $40 per product for inspection and $4,720, or $80 per
seat for parts replacement.
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:
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 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
Air transportation, Aircraft, Aviation safety, Safety.
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
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by adding the following new AD:
Pilatus Aircraft Limited: Docket No. FAA-2006-26371; Directorate
Identifier 2006-CE-70-AD.
Comments Due Date
(a) We must receive comments by January 10, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to PC-12 and PC-12/45 airplanes, serial
numbers 101 through 683, that are:
(1) Certificated in any category; and
(2) Equipped with executive passenger seats Model Number 4006
manufactured by DeCrane Aircraft Seating Company, Inc. Vendor Part
Number (VPN) 403150-1 or 403150-2 with Serial Numbers (S/N)
identified in DeCrane Aircraft Mandatory Service Bulletin SB05147
Revision B, dated June 26, 2006.
Reason
(d) The mandatory continuing airworthiness information (MCAI)
states that executive seats equipped with pedestal legs were
produced using a material that deviates from the approved design
data. As a consequence the pedestal legs may not perform as intended
under emergency landing conditions. In order to correct and control
the situation, this AD requires a one time inspection to identify
the VPN of the pedestal legs and the S/N of the executive seat and
the replacement of the pedestal legs if necessary.
Actions and Compliance
(e) Unless already done, do the following actions.
(1) Within 30 days after the effective date of this AD:
(i) Perform an inspection to identify the VPN of the pedestal
legs and the S/N of the executive seat following the accomplishment
instructions in Pilatus PC-12 Service Bulletin No.: 25-032, dated
October 2, 2006.
(ii) If during the inspection required by paragraph (e)(1)(i) of
this AD any pedestal legs with a VPN and executive seats with a S/N
which correspond with the data in DeCrane Aircraft Mandatory Service
Bulletin SB05147 Revision B, dated June 26, 2006 are found, prior to
further flight, replace the affected pedestal legs following the
accomplishment instructions in Pilatus PC-12 Service Bulletin No.:
25-032, dated October 2, 2006, with new pedestal legs with VPN
431005-17 and 431005-18. The removed parts must be returned to
Pilatus.
(2) As of the effective date of this AD, no person shall install
any executive seats model number 4006 produced by DeCrane Aircraft
Seating Company, Inc., VPN 403150-1 or 403150-2 with S/Ns identified
in DeCrane Aircraft Mandatory Service Bulletin SB05147 Revision B,
dated June 26, 2006, on any Pilatus Models PC-12 and PC-12/45
airplane, unless the mandatory actions of this AD have been
implemented.
