Airworthiness Directives; PILATUS 

Aircraft Ltd. Model PC–7 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) 

originated 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: This Airworthiness 

Directive (AD) is prompted due to an 

occurrence when an aircraft had a 

partial in-flight separation of the aileron 

outboard bearing support. The aileron 

outboard bearing supports are attached 

with two forward attachment bolts and 

two aft attachment bolts. The forward 

attachment bolts are approximately 3.2 

mm (0.125 inch) longer than the aft 

attachment bolts. If the aileron outboard 

bearing supports have been removed, it 

is possible that during the reinstallation 

of the aileron outboard bearing 

supports, the attachment bolts can be 

installed in wrong positions. Bolts that 

are installed in wrong positions can 

damage the threads in the rear 

attachment anchor nuts. Such a 

condition, if left uncorrected, could lead 

to in-flight separation of the aileron 

outboard bearing support, and as a 

consequence, the loss or limited 

controllability of the aircraft. The 

proposed AD would require actions that 

are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by October 12, 2010. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to

Discussion 

The Federal Office of Civil Aviation 

(FOCA), which is the aviation authority 

for Switzerland, has issued AD HB– 

2010–010, dated July 29, 2010 (referred 

to after this as ‘‘the MCAI’’), to correct 

an unsafe condition for the specified 

products. The MCAI states: 

This Airworthiness Directive (AD) is 

prompted due to an occurrence when an 

aircraft had a partial in-flight separation of 

the aileron outboard bearing support. 

The aileron outboard bearing supports are 

attached with two forward attachment bolts 

and two aft attachment bolts. The forward 

attachment bolts are approximately 3.2 mm 


erowe on DSKG8SOYB1PROD with PROPOSALS-1
Federal Register / Vol. 75, No. 165 / Thursday, August 26, 2010 / Proposed Rules 52483 

(0.125 inch) longer than the aft attachment 

bolts. If the aileron outboard bearing supports 

have been removed, it is possible that during 

the reinstallation of the aileron outboard 

bearing supports, the attachment bolts can be 

installed in wrong positions. Bolts that are 

installed in wrong positions can damage the 

threads in the rear attachment anchor nuts. 

Such a condition, if left uncorrected, could 

lead to in-flight separation of the aileron 

outboard bearing support, and as a 

consequence, the loss or limited 

controllability of the aircraft. 

In order to correct and control the 

situation, this AD requires a one time 

inspection to verify that the bolts are 

installed in the correct positions and the 

threads of the anchor nuts are in good 

condition. The replacement of the attachment 

hardware is required if any damage on the 

anchor nut threads or a bolt at the wrong 

location is found. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Pilatus Aircraft Ltd. has issued PC–7 

Service Bulletin No. 57–015, Rev. No. 1, 

date July 23, 2010. 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 

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 

highlighted in a Note within the 

proposed AD. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 12 products of U.S. registry. 

We also estimate that it would take 

about 2 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $2,040, or $170 per 

product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 25 work-hours and require parts 

costing $200, for a cost of $2,325 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows:

DIRECTIVES 

1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

2. The FAA amends § 39.13 by adding 

the following new AD: 

Pilatus Aircraft Ltd.: Docket No. FAA–2010– 

0849; Directorate Identifier 2010–CE– 

043–AD. 

Comments Due Date 

(a) We must receive comments by October 

12, 2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to PILATUS Aircraft 

Ltd. Model PC–7 airplanes, manufacturer 

serial numbers (MSN) 101 through 618, 

certificated in any category. 

Subject 

(d) Air Transport Association of America 

(ATA) Code 57: Wings. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

This Airworthiness Directive (AD) is 

prompted due to an occurrence when an 

aircraft had a partial in-flight separation of 

the aileron outboard bearing support. 

The aileron outboard bearing supports are 

attached with two forward attachment bolts 

and two aft attachment bolts. The forward 

attachment bolts are approximately 3.2 mm 

(0.125 inch) longer than the aft attachment 

bolts. If the aileron outboard bearing supports 

have been removed, it is possible that during 

the reinstallation of the aileron outboard 

bearing supports, the attachment bolts can be 

installed in wrong positions. Bolts that are 

installed in wrong positions can damage the 

threads in the rear attachment anchor nuts. 

Such a condition, if left uncorrected, could 

lead to in-flight separation of the aileron 

outboard bearing support, and as a 

consequence, the loss or limited 

controllability of the aircraft. 

In order to correct and control the 

situation, this AD requires a one time 

inspection to verify that the bolts are 


erowe on DSKG8SOYB1PROD with PROPOSALS-1
52484 Federal Register / Vol. 75, No. 165 / Thursday, August 26, 2010 / Proposed Rules 

installed in the correct positions and the 

threads of the anchor nuts are in good 

condition. The replacement of the attachment 

hardware is required if any damage on the 

anchor nut threads or a bolt at the wrong 

location is found. 

Actions and Compliance 

(f) Unless already done, do the following 

actions: 

(1) Within 1 month after the effective date 

of this AD, check the airplane maintenance 

records to determine if the left and/or right 

aileron outboard bearing supports have been 

removed at any time during the life of the 

airplane. Do this check following paragraph 

3.A. of Pilatus Aircraft Ltd. PC–7 Service 

Bulletin No. 57–015, Rev. No. 1, date July 23, 

2010. 

(2) If an entry is found during the airplane 

maintenance records check required in 

paragraph (f)(1) of this AD or it is unclear 

whether or not the left and/or right aileron 

outboard bearing supports have been 

removed, perform the actions following the 

instructions in paragraph 3.A.(2) through 

paragraph 3.E of Pilatus Aircraft Ltd. PC–7 

Service Bulletin No. 57–015, Rev. No. 1, date 

July 23, 2010.
