SUMMARY: We are revising an earlier 

NPRM for all PILATUS AIRCRAFT LTD. 

Models PC–12, PC–12/45, PC–12/47, 

and PC–12/47E airplanes. 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 a need to 

incorporate new revisions into the 

Limitations section, Chapter 4, of the 

FAA-approved maintenance program 

(e.g., maintenance manual). We are 

issuing this proposed AD to require 

actions to address the unsafe condition 

on these products.

Discussion 

We proposed to amend 14 CFR part 

39 with an earlier NPRM for the 

specified products, which was 

published in the Federal Register on 

July 18, 2012 (77 FR 42225). That earlier 

NPRM (77 FR 42225, July 18, 2012) 

proposed to require actions intended to 

address the unsafe condition for the 

products listed above. 

Since that NPRM (77 FR 42225, July 

18, 2012), was issued, PILATUS 

AIRCRAFT LTD. has issued updated 

revisions to the Structural and 

Component Airworthiness Limitations 

documents. 

Relevant Service Information 

Pilatus Aircraft Ltd. has issued Pilatus 

PC12 Aircraft Maintenance Manual 

Temporary Revision No. 04–03, dated 

October 12, 2012, which transmits 

Unclassified 12–A/AMP–04 Structural, 

Component and Miscellaneous— 

Airworthiness Limitations, document 

12–A–04–00–00–00A–000A–A, dated 

October 15, 2012; and PC12/47E Aircraft 

Maintenance Manual Temporary 

Revision No. 04–01, dated October 15, 

2012, which transmits Unclassified 12– 

B/AMP–04 Structural and Component 

Limitations—Airworthiness Limitations, 

document 12–B–04–00–00–00A–000A– 

A, dated October 15, 2012. The actions 

described in this service information are 

intended to correct the unsafe condition 

identified in the MCAI. 

Comments 

We have considered the following 

comment received on the earlier NPRM 

(77 FR 42225, July 18, 2012). 

Johan Kruger of PILATUS AIRCRAFT 

LTD. requested the FAA to incorporate 

new revisions of the Structural and 

Component Airworthiness Limitations 

documents into the proposed AD. These 

revisions incorporate a change to the 

fire extinguisher life limit, correct the 

flap control and warning unit (FCWU) 

part number, and change the description 

of the cockpit inner and outer window 

damage. 

We agree with the commenter. In 

order to ensure that the owners/ 

operators of the affected airplanes are 

using the correct limitations for their 

FAA-approved maintenance program, 

we are incorporating the new revisions 

to the Structural and Component 

Airworthiness Limitations documents 

into this proposed AD. 

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 

supplemental NPRM 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. 

Certain changes described above expand 

the scope of the original NPRM (77 FR 

42225, July 18, 2012). As a result, we 

have determined that it is necessary to 

reopen the comment period to provide 

additional opportunity for the public to 

comment on this supplemental NPRM.

Federal Register / Vol. 77, No. 204 / Monday, October 22, 2012 / Proposed Rules 64443 

Costs of Compliance 

We estimate that this proposed AD 

would affect 678 products of U.S. 

registry. We also estimate that it would 

take about 3.5 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 $300 per product. Based on 

these figures, we estimate the cost of 

this proposed AD on U.S. operators to 

be $405,105, or $597.50 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 6 work-hours and require parts 

costing $4,000, for a cost of $4,510 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

We also estimate that it would take 

about 12 work-hours per product to 

comply with the addition of the wing 

inspection 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 wing inspection 

on U.S. operators to be $691,560, or 

$1,020 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 7 work-hours and require parts 

costing approximately $5,000, for a cost 

of $5,595 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), 

(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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

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–2012–0732; Directorate Identifier 

2012–CE–022–AD. 

(a) Comments Due Date 

We must receive comments by December 6, 

2012. 

(b) Affected ADs 

This AD supersedes AD 2009–14–13, 

Amendment 39–15963 (74 FR 34213, July 15, 

2009). 

(c) Applicability 

This AD applies to PILATUS AIRCRAFT 

LTD. Models PC–12, PC–12/45, PC–12/47, 

and PC–12/47E airplanes, all manufacturer 

serial numbers (MSNs), certificated in any 

category. 

(d) Subject 

Air Transport Association of America 

(ATA) Code 05: Time Limits. 

(e) Reason 

This AD was prompted by 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 a need to 

incorporate new revisions into the 

Limitations section, Chapter 4, of the FAAapproved maintenance program (e.g., 

maintenance manual). The limitations were 

revised to include an inspection of the wing 

main spar fastener holes at rib 6 for cracks. 

These actions are required to ensure the 

continued operational safety of the affected 

airplanes. 

(f) Actions and Compliance 

Unless already done, do the following 

actions: 

(1) For Models PC–12 and PC–12/45 

airplanes, MSNs 101 through 299: Within the 

next 100 hours time-in-service (TIS) after 

August 19, 2009 (the effective date retained 

from AD 2009–14–13, Amendment 39–15963 

(74 FR 34213, July 15, 2009)) or 1 year after 

August 19, 2009 (the effective date retained 

from AD 2009–14–13), whichever occurs 

first, replace the torque tube part number (P/ 

N) 532.50.12.047 with torque tube P/N 

532.50.12.064 following PILATUS 

AIRCRAFT LTD. Service Bulletin No: 32– 

021, dated November 21, 2008.
