gear (MLG) assemblies for any part
number (P/N) 532.10.12.077 bolts that
do not have white primed and painted
heads; and replace any bolt found with
new P/N 532.10.12.077F bolts in all
MLG assemblies. This proposed AD
results from mandatory continuing
airworthiness information (MCAI)
issued by the airworthiness authority for
Switzerland. We are issuing this
proposed AD to detect and correct any
P/N 532.10.12.077 bolts that do not have
white primed and painted heads, which
could result in corrosion of the bolt and
consequent failure of the bolt. This
failure could lead to MLG collapse
during airplane landing and take-off
operations with consequent loss of
airplane control.

Discussion
What events have caused this
proposed AD? The Federal Office for
Civil Aviation (FOCA), which is the
airworthiness authority for Switzerland,
recently notified FAA that an unsafe
condition may exist on certain Pilatus
Models PC–12 and PC–12/45 airplanes.
The FOCA reports part number (P/N)
532.10.12.077 bolts that do not have
white primed and painted heads are
subject to corrosion. These bolts attach
the hydraulic actuators to the left and
right main landing gear (MLG)
assemblies. The FOCA further reports
the separation of a bolt head in an MLG
assembly has occurred due to corrosion.
The corrosion occurred because the bolt
head was not primed and painted.
Pilatus has designed and produced a
new bolt (P/N 532.10.077F) as part of
Modification Kit No. 500.50.12.299 to
replace the subject bolt. Pilatus
recommends the replacement of bolts in
pairs.
What is the potential impact if FAA
took no action? Corrosion of the bolt
could lead to MLG collapse during
airplane landing and take-off operations
with consequent loss of airplane
control.
Is there service information that
applies to this subject? Pilatus has
issued Pilatus PC12 Service Bulletin No.
32–018, dated May 2, 2005.
What are the provisions of this service
information? The service bulletin
includes procedures for:
—Inspecting the MLG assemblies to find
P/N 532.10.12.077 bolts that do not
have white primed and painted heads;
and
—Replacing any P/N 532.10.12.077
bolts that do not have primed and
painted heads with new P/N
532.10.077F bolts in all MLG
assemblies.
What action did the FOCA take? The
FOCA classified this service bulletin as
mandatory and issued Swiss AD
Number HB–2005–288, dated June 29,
2005, to ensure the continued
airworthiness of these airplanes in
Switzerland.
Did the FOCA inform the United
States under the bilateral airworthiness
agreement? These Pilatus Models PC–12
and PC–12/45 airplanes are
manufactured in Switzerland and are
type-certificated for operation in the
United States under the provisions of
section 21.29 of the Federal Aviation
Regulations (14 CFR 21.29) and the
applicable bilateral airworthiness
agreement.
Under this bilateral airworthiness
agreement, the FOCA has kept us
informed of the situation described
above.
FAA’s Determination and Requirements
of This Proposed AD
What has FAA decided? We have
examined the FOCA’s findings,
reviewed all available information, and
determined that AD action is necessary
for products of this type design that are
certificated for operation in the United
States.
Since the unsafe condition described
previously is likely to exist or develop
on other Pilatus Models PC–12 and PC–
12/45 airplanes of the same type design
that are registered in the United States,
we are proposing AD action to detect
and correct any P/N 532.10.12.077 bolts
that do not have white primed and
painted heads, which could result in
corrosion of the bolt and consequent
failure of the bolt. This failure could
lead to MLG collapse during airplane
landing and take-off operations with
consequent loss of airplane control.
What would this proposed AD
require? This proposed AD would
require you to incorporate the actions in
the previously-referenced service
bulletin.
How does the revision to 14 CFR part
39 affect this proposed AD? On July 10,
2002, we published a new version of 14
CFR part 39 (67 FR 47997, July 22,
2002), which governs FAA’s AD system.
This regulation now includes material
that relates to altered products, special
flight permits, and alternative methods
of compliance. This material previously
was included in each individual AD.
Since this material is included in 14
CFR part 39, we will not include it in
future AD actions.
Costs of Compliance
How many airplanes would this
proposed AD impact? We estimate that
this proposed AD affects 350 airplanes
in the U.S. registry.
What would be the cost impact of this
proposed AD on owners/operators of the
affected airplanes? We estimate the
following costs to do this proposed
inspection:
Total cost per
airplaine
Labor cost
Parts cost
1 work hour × $65 per hour = $65 ..........................................................

Federal Register / Vol. 70, No. 147 / Tuesday, August 2, 2005 / Proposed Rules
We estimate the following costs to do
any necessary single bolt replacement
(using Modification Kit No.
500.50.12.299) that would be required
based on the results of this proposed
inspection. We have no way of
Labor cost
determining the number of airplanes
that may need this bolt replacement:
Total cost per
airplane
Parts cost
3 work hours × $65 per hour = $195 ........................................
Pilatus will provide warranty credit
for inspecting and replacing the
specified bolts to the extent stated in the
service information.
Authority for This Rulemaking
What authority does FAA have for
issuing this rulemaking action? 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
Would this proposed AD impact
various entities? We have 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.
$1,000 estimate for each Modification Kit No. 500.50.12.299
Would this proposed AD involve a
significant rule or regulatory action? For
the reasons discussed above, I certify
that this proposed 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 proposed 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 ‘‘AD Docket FAA–2005–21835;
Directorate Identifier 2005–CE–35–AD’’
in your request.

RIN 2120-AA64
Airworthiness Directives; Pilatus Aircraft Ltd. Models PC-12 and
PC-12/45 Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Pilatus Aircraft Ltd. (Pilatus) Models PC-12 and PC-12/45
airplanes. This proposed AD would require you to inspect the left and
right main landing gear (MLG) assemblies for any part number (P/N)
532.10.12.077 bolts that do not have white primed and painted heads;
and replace any bolt found with new P/N 532.10.12.077F bolts in all MLG
assemblies. This proposed AD results from mandatory continuing
airworthiness information (MCAI) issued by the airworthiness authority
for Switzerland. We are issuing this proposed AD to detect and correct
any P/N 532.10.12.077 bolts that do not have white primed and painted
heads, which could result in corrosion of the bolt and consequent
failure of the bolt. This failure could lead to MLG collapse during
airplane landing and take-off operations with consequent loss of
airplane control.

Discussion
What events have caused this proposed AD? The Federal Office for
Civil Aviation (FOCA), which is the airworthiness authority for
Switzerland, recently notified FAA that an unsafe condition may exist
on certain Pilatus Models PC-12 and PC-12/45 airplanes. The FOCA
reports part number (P/N) 532.10.12.077 bolts that do not have white
primed and painted heads are subject to corrosion. These bolts attach
the hydraulic actuators to the left and right main landing gear (MLG)
assemblies. The FOCA further reports the separation of a bolt head in
an MLG assembly has occurred due to corrosion. The corrosion occurred
because the bolt head was not primed and painted.
Pilatus has designed and produced a new bolt (P/N 532.10.077F) as
part of Modification Kit No. 500.50.12.299 to replace the subject bolt.
Pilatus recommends the replacement of bolts in pairs.
What is the potential impact if FAA took no action? Corrosion of
the bolt could lead to MLG collapse during airplane landing and take-
off operations with consequent loss of airplane control.
Is there service information that applies to this subject? Pilatus
has issued Pilatus PC12 Service Bulletin No. 32-018, dated May 2, 2005.
What are the provisions of this service information? The service
bulletin includes procedures for:
--Inspecting the MLG assemblies to find P/N 532.10.12.077 bolts that do
not have white primed and painted heads; and
--Replacing any P/N 532.10.12.077 bolts that do not have primed and
painted heads with new P/N 532.10.077F bolts in all MLG assemblies.
What action did the FOCA take? The FOCA classified this service
bulletin as mandatory and issued Swiss AD Number HB-2005-288, dated
June 29, 2005, to ensure the continued airworthiness of these airplanes
in Switzerland.
Did the FOCA inform the United States under the bilateral
airworthiness agreement? These Pilatus Models PC-12 and PC-12/45
airplanes are manufactured in Switzerland and are type-certificated for
operation in the United States under the provisions of section 21.29 of
the Federal Aviation Regulations (14 CFR 21.29) and the applicable
bilateral airworthiness agreement.
Under this bilateral airworthiness agreement, the FOCA has kept us
informed of the situation described above.
FAA's Determination and Requirements of This Proposed AD
What has FAA decided? We have examined the FOCA's findings,
reviewed all available information, and determined that AD action is
necessary for products of this type design that are certificated for
operation in the United States.
Since the unsafe condition described previously is likely to exist
or develop on other Pilatus Models PC-12 and PC-12/45 airplanes of the
same type design that are registered in the United States, we are
proposing AD action to detect and correct any P/N 532.10.12.077 bolts
that do not have white primed and painted heads, which could result in
corrosion of the bolt and consequent failure of the bolt. This failure
could lead to MLG collapse during airplane landing and take-off
operations with consequent loss of airplane control.
What would this proposed AD require? This proposed AD would require
you to incorporate the actions in the previously-referenced service
bulletin.
How does the revision to 14 CFR part 39 affect this proposed AD? On
July 10, 2002, we published a new version of 14 CFR part 39 (67 FR
47997, July 22, 2002), which governs FAA's AD system. This regulation
now includes material that relates to altered products, special flight
permits, and alternative methods of compliance. This material
previously was included in each individual AD. Since this material is
included in 14 CFR part 39, we will not include it in future AD
actions.
Costs of Compliance
How many airplanes would this proposed AD impact? We estimate that
this proposed AD affects 350 airplanes in the U.S. registry.
What would be the cost impact of this proposed AD on owners/
operators of the affected airplanes? We estimate the following costs to
do this proposed inspection:
----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplaine U.S. operators
----------------------------------------------------------------------------------------------------------------
1 work hour x $65 per hour = $65............. Not applicable................. $65 $22,750
----------------------------------------------------------------------------------------------------------------
[[Page 44299]]
We estimate the following costs to do any necessary single bolt
replacement (using Modification Kit No. 500.50.12.299) that would be
required based on the results of this proposed inspection. We have no
way of determining the number of airplanes that may need this bolt
replacement:
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
3 work hours x $65 per hour = $1,000 estimate for $1,195
$195. each Modification Kit
No. 500.50.12.299.
------------------------------------------------------------------------
Pilatus will provide warranty credit for inspecting and replacing
the specified bolts to the extent stated in the service information.
Authority for This Rulemaking
What authority does FAA have for issuing this rulemaking action?
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
Would this proposed AD impact various entities? We have 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.
Would this proposed AD involve a significant rule or regulatory
action? For the reasons discussed above, I certify that this proposed
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 proposed 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
``AD Docket FAA-2005-21835; Directorate Identifier 2005-CE-35-AD'' in
your request.
