AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for 

PILATUS AIRCRAFT LTD. Model PC– 

12/47 and PC–12/47E airplanes. This 

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 the aileron trim tab 

disconnecting above 10,000 feet 

altitude. We are issuing this AD to 

require actions to address the unsafe 

condition on these products. 

DATES: This AD is effective August 20, 

2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of August 20, 2015.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to adding an AD that would 

apply to PILATUS AIRCRAFT LTD. 

Model PC–12/47 and PC–12/47E 

airplanes. The NPRM was published in 

the Federal Register on May 1, 2015 (80 

FR 24854). The NPRM proposed to 

correct an unsafe condition for the 

specified products and was based on 

mandatory continuing airworthiness 

information (MCAI) originated by an 

aviation authority of another country. 

The MCAI states: 

During a continued airworthiness review, a 

potential unsafe condition was identified that 

could result from a disconnected aileron trim 

tab occurring above an altitude of 10.000 feet. 

This condition, if not corrected, could lead, 

in case of a disconnection of an aileron trim 

tab, to undamped aeroplane vibrations, 

potentially resulting in structural failure. 

To address this potential unsafe condition, 

Pilatus Aircraft Ltd. issued SB No. 27–021 to 

provide instructions for replacement of the 

aileron tab counter balance weight. 

For the reason described above, this AD 

requires replacement of the aileron tab 

counter balance weight with a new, slightly 

heavier, aileron tab counter balance weight. 

The MCAI can be found in the AD 

docket on the Internet at: http://

www.regulations.gov/

#!documentDetail;D=FAA-2015-1177- 

0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal and the FAA’s 

response to each comment. 

Request Revision of Paragraph (e) 

Reason of the AD 

Johan Kruger stated the sentence of 

paragraph (e) Reason in the proposed 

AD was incomplete and misleading: 

We are issuing this AD to prevent a 

disconnected aileron trim tab, which could 

lead to undamped airplane vibrations, 

potentially resulting in structural failure. 

Johan Kruger proposed replacing the 

above sentence with this sentence 

similar to the MCAI: 

We are issuing this AD to prevent 

undamped airplane vibrations, potentially 

resulting in structural failure in case of a 

disconnected aileron trim tab. 

We agree with the commenter that the 

proposed sentence is clarification of the 

unsafe condition. We have adopted the 

proposed sentence in paragraph (e) of 

the AD. 

Request Correction of Part Number 

(P/N) 

Johan Kruger stated the cited part 

number (P/N) 27.15.12.037 of the 

aileron trim tab assembly quoted is 

wrong in paragraphs (f)(2) and (f)(3) of 

the proposed AD; the correct P/N is 

527.15.12.037. We infer that the 

commenter requested correction of the 

incorrect P/N. 

We agree with the commenter that the 

P/N in the proposed AD is incorrect. We 

have changed the incorrect P/N to 

527.15.12.037 in paragraphs (f)(2) and 

(f)(3) of the AD. 

Request Correction of Misleading 

Wording in Paragraph (f)(4) of the AD 

Johan Kruger commented the wording 

in paragraph 2(f)(4) is misleading, ‘‘. . . 

provided that an aileron trim tab 

assembly, P/N 527.15.12.037 or 

527.15.12.038 is not installed on the 

airplane.’’ 

Johan Kruger further wrote that 

Pilatus proposed the wording be 

changed to read, ‘‘. . . provided that an 


tkelley on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 80, No. 136 / Thursday, July 16, 2015 / Rules and Regulations 42019 

aileron trim tab assembly, P/N 

527.15.12.037 or 527.15.12.038 is not 

installed on that aileron assembly.’’ 

We infer the commenter means 

paragraph (f)(4) of the AD. 

We agree with the commenter. 

Aileron trim tab assemblies will only be 

associated with aileron assemblies and 

not by airplane. The aileron assemblies 

themselves are associated with the 

airplane number. We have adopted the 

proposed wording in paragraph (f)(4) of 

the AD. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (80 FR 

24854, May 1, 2015) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (80 FR 24854, 

May 1, 2015). 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of the AD. 

Relative Service Information Under 1 

CFR Part 51 

We reviewed PILATUS AIRCRAFT 

LTD. PILATUS PC–12 Service Bulletin 

No: 27–021, dated January 20, 2015. The 

service information describes 

procedures for replacement of the 

aileron tab counter balance weight. This 

service information is reasonably 

available because the interested parties 

have access to it through their normal 

course of business or by the means 

identified in the ADDRESSES section of 

this final rule. 

Costs of Compliance 

We estimate that this AD will affect 

303 products of U.S. registry. We also 

estimate that it would take about 5.5 

work hours per product to comply with 

the basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts would cost about $1,000 

per product. 

Based on these figures, we estimate 

the cost of the AD on U.S. operators to 

be $444,652.50, or $1,467.50 per 

product. 

According to the manufacturer, some 

of the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected individuals. We 

do not control warranty coverage for 

affected individuals. As a result, we 

have included all costs in our cost 

estimate. 

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 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 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), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) 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. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2015– 

1177; or in person at the Docket 

Management Facility between 9 a.m. 

and 5 p.m., Monday through Friday,

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

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. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of airspace necessary to ensure the 

safety of aircraft and the efficient use of
