ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for Pilatus 

Aircraft Ltd. Models PC–6, PC–6–H1, 

PC–6–H2, PC–6/350, PC–6/350–H1, PC–

B2–H2, PC–6/B2–H4, PC–6/C–H2, and 

PC–6/C1–H2 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 loose elevator and rudder 

hinge bolts caused by incorrect torquing 

and locking of the bolts, which could 

lead to in-flight failure of the elevator or 

rudder attachment. We are issuing this 

AD to require actions to address the 

unsafe condition on these products. 

DATES: This AD is effective May 4, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of May 4, 2012.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on January 17, 2012 (77 FR 

2238). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

A case of loss of elevator and rudder hinge 

bolts on a PC–6 aeroplane has been reported. 

The results of the investigations indicate 

that the elevator and rudder hinge bolt loss 

are suspected to have been caused by an 

incorrect torque and locking of the bolts. 

This condition, if not detected and 

corrected, could lead to in-flight failure of the 

elevator or rudder attachment, possibly 

resulting in loss of control of the aeroplane. 

For the reasons described above, this AD 

requires the installation of a new locking 

screw and the modification of the installation 

of the hinge bolt.

You may obtain further information by 

examining the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (77 

FR 2238, January 17, 2012) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 2238, 

January 17, 2012) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 2238, 

January 17, 2012). 

Costs of Compliance 

We estimate that this AD will affect 

50 products of U.S. registry. We also 

estimate that it will take about 5 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $100 per 

product. 

Based on these figures, we estimate 

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

be $26,250, or $525 per product. 

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; or in person at the 

Docket Management Facility between 9 

a.m. and 5 p.m., Monday through 

Friday, except Federal holidays. The AD 

docket contains the NPRM (77 FR 2238, 

January 17, 2012), the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Office (telephone (800) 647– 

5527) is in the ADDRESSES section. 

Comments will be available in the AD 

docket shortly after receipt.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on January 17, 2012 (77 FR 

2234). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Occurrence of damage of the bulkhead of 

CG tow hook and its glued joints to fuselage 

shell was reported. 

Investigation concluded that this damage 

may occur after wheel up landing. 

Damage of bulkheads for CG tow hook of 

the sailplane or powered sailplane, if not 

detected and corrected, may lead to failure of 

glass fibre structure during a winch launch. 

DG-Flugzeugbau GmbH developed and 

published Technical Note (TN) No 500/04 

with the associated Working Instruction No. 

1 to detect and correct damaged CG tow hook 

bulkhead and its glued joints. 

For the above-mentioned reasons, this AD 

requires a one-time inspection of the CG tow 

hook and its reinforcement. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (77 

FR 2234, January 17, 2012) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 2234, 

January 17, 2012) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 2234, 

January 17, 2012).
