Airworthiness Directives; Pilatus
Aircraft Ltd. Model PC–7 Airplanes
Federal Aviation
Administration (FAA), DOT.
ACTION: Final rule.
AGENCY:
SUMMARY: The FAA adopts a new
airworthiness directive (AD) for certain
Pilatus Aircraft Ltd. (Pilatus) Model PC–
7 airplanes. This AD requires you to do
repetitive eddy-current, non-destructive
inspections of the nose skin and
adjacent structure above the left and
right main landing gear bay and
repetitive visual inspections of the
forward support structure of the floor
panel for crack damage. If you find any
crack damage, this AD requires you to
contact Pilatus to obtain a repair
solution and incorporate the repair. This
AD results from mandatory continuing
airworthiness information (MCAI)
issued by the airworthiness authority for
Switzerland. We are issuing this AD to
detect and correct cracks in the nose
skin and adjacent structure above the
left and right main landing gear bay and

Sfmt 4700
On September 11, 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 Pilatus Model PC–7 airplanes.
This proposal was published in the
Federal Register as a notice of proposed
rulemaking (NPRM) on September 15,
2006 (71 FR 54441). The NPRM
proposed to require you to do repetitive
eddy-current, non-destructive
inspections of the nose skin and
adjacent structure above the left and
right main landing gear bay and
repetitive visual inspections of the
forward support structure of the floor
panel for crack damage. If crack damage
is found, the NPRM proposed to require
you to contact Pilatus to obtain a repair
solution and incorporate the repair.
Comments
We provided the public the
opportunity to participate in developing
this AD. The following presents the
comments received on the proposal and
FAA’s response to each comment:
We received one comment from
Pilatus Aircraft in favor of the proposed
AD.

Federal Register / Vol. 71, No. 216 / Wednesday, November 8, 2006 / Rules and Regulations
Comment Issue No. 1: Publish the
Manufacturer Service Information
Jack Buster with the Modification and
Replacement Parts Association
(MARPA) provides comments on the
MCAI AD process pertaining to how the
FAA addresses publishing manufacturer
service information as part of a
proposed AD action. The commenter
states that the proposed rule attempts to
require compliance with a public law by
reference to a private writing (as
referenced in paragraph (e) of the
proposed AD). The commenter would
like the FAA to incorporate by reference
(IBR) the Pilatus service bulletin.
We agree with Mr. Buster. However,
we do not IBR any document in a
proposed AD action, instead we IBR the
document in the final rule. Since we are
issuing the proposal as a final rule AD
action, Pilatus PC–7 Service Bulletin
No. 57–009, dated January 29, 2004, is
incorporated by reference.
Comment Issue No. 2: Availability of
IBR Documents in the Docket
Management System (DMS)
Mr. Buster requests IBR documents be
made available to the public by
publication in the Federal Register or in
the DMS.
We are currently reviewing issues
surrounding the posting of service
bulletins in the Department of
Transportation’s DMS as part of the AD
docket. Once we have thoroughly
examined all aspects of this issue and
have made a final determination, we
will consider whether our current
practice needs to be revised.
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.
Differences Between the FOCA AD, the
Service Information, and This AD
The FOCA AD HB–2006–374,
effective date August 2, 2006, allows
continued flight if cracks are found in
the nose skin that do not exceed certain
limits. The applicable service bulletin
specifies repair of the nose skin only if
cracks are found exceeding limits
illustrated in Pilatus PC–7 Service
Bulletin No. 57–009, dated January 29,
2004, as does FOCA AD HB–2006–374,
effective date August 2, 2006. This AD
does not allow continued flight if any
crack is found. The FAA policy is to
disallow airplane operation when
known cracks exist in primary structure,
unless the ability to sustain ultimate
load with these cracks is proven. The
nose skin is considered primary
structure, and the FAA has not received
any analysis to prove that ultimate load
can be sustained with cracks in this
area.
The requirements of this AD take
precedence over the provisions in the
service information.
Costs of Compliance
We estimate that this AD affects 10
airplanes in the U.S. registry.
We estimate the following costs to
accomplish the inspection:
Total cost per
airplane
Labor cost
Parts cost
3 work-hours × $80 per hour = $240 ...........................
$240
$2,400
No parts required ..........................................................
Any required ‘‘upon-condition’’
repairs will vary depending upon the
damage found. Based on this, we have
no way of determining the potential
repair costs for each airplane or the
number of airplanes that will need the
repairs based on the result of the
inspections.
Authority for This Rulemaking
pwalker on PRODPC60 with RULES
Total cost on
U.S. operators
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

SUPPLEMENTARY INFORMATION:
Discussion
On September 11, 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 Pilatus Model PC-7 airplanes. This proposal was
published in the Federal Register as a notice of proposed rulemaking
(NPRM) on September 15, 2006 (71 FR 54441). The NPRM proposed to
require you to do repetitive eddy-current, non-destructive inspections
of the nose skin and adjacent structure above the left and right main
landing gear bay and repetitive visual inspections of the forward
support structure of the floor panel for crack damage. If crack damage
is found, the NPRM proposed to require you to contact Pilatus to obtain
a repair solution and incorporate the repair.
Comments
We provided the public the opportunity to participate in developing
this AD. The following presents the comments received on the proposal
and FAA's response to each comment:
We received one comment from Pilatus Aircraft in favor of the
proposed AD.
[[Page 65388]]
Comment Issue No. 1: Publish the Manufacturer Service Information
Jack Buster with the Modification and Replacement Parts Association
(MARPA) provides comments on the MCAI AD process pertaining to how the
FAA addresses publishing manufacturer service information as part of a
proposed AD action. The commenter states that the proposed rule
attempts to require compliance with a public law by reference to a
private writing (as referenced in paragraph (e) of the proposed AD).
The commenter would like the FAA to incorporate by reference (IBR) the
Pilatus service bulletin.
We agree with Mr. Buster. However, we do not IBR any document in a
proposed AD action, instead we IBR the document in the final rule.
Since we are issuing the proposal as a final rule AD action, Pilatus
PC-7 Service Bulletin No. 57-009, dated January 29, 2004, is
incorporated by reference.
Comment Issue No. 2: Availability of IBR Documents in the Docket
Management System (DMS)
Mr. Buster requests IBR documents be made available to the public
by publication in the Federal Register or in the DMS.
We are currently reviewing issues surrounding the posting of
service bulletins in the Department of Transportation's DMS as part of
the AD docket. Once we have thoroughly examined all aspects of this
issue and have made a final determination, we will consider whether our
current practice needs to be revised.
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.
Differences Between the FOCA AD, the Service Information, and This AD
The FOCA AD HB-2006-374, effective date August 2, 2006, allows
continued flight if cracks are found in the nose skin that do not
exceed certain limits. The applicable service bulletin specifies repair
of the nose skin only if cracks are found exceeding limits illustrated
in Pilatus PC-7 Service Bulletin No. 57-009, dated January 29, 2004, as
does FOCA AD HB-2006-374, effective date August 2, 2006. This AD does
not allow continued flight if any crack is found. The FAA policy is to
disallow airplane operation when known cracks exist in primary
structure, unless the ability to sustain ultimate load with these
cracks is proven. The nose skin is considered primary structure, and
the FAA has not received any analysis to prove that ultimate load can
be sustained with cracks in this area.
The requirements of this AD take precedence over the provisions in
the service information.
Costs of Compliance
We estimate that this AD affects 10 airplanes in the U.S. registry.
We estimate the following costs to accomplish the inspection:
----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
3 work-hours x $80 per hour = $240............ No parts required............... $240 $2,400
----------------------------------------------------------------------------------------------------------------
Any required ``upon-condition'' repairs will vary depending upon
the damage found. Based on this, we have no way of determining the
potential repair costs for each airplane or the number of airplanes
that will need the repairs based on the result of the inspections.
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-2006-25582; Directorate Identifier 2006-CE-42-AD'' in your
request.

Unsafe Condition
(d) This AD is the result of mandatory continuing airworthiness
information (MCAI) issued by the airworthiness authority for
Switzerland. The actions specified in this AD are intended to detect
and correct cracks in the nose skin and adjacent structure above the
left and right main landing gear bay and in the forward support
structure of the floor panel. Crack propagation in certain areas
could lead to failure of the main wing torsion box. This failure
could result in loss of control.
