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: 

Reports have been received indicating that, 

if the power control friction wheel is 

tightened, the reverse thrust latch may stick 

and subsequently allow the Power Control 

Lever (PCL) to be inadvertently retarded aft 

of the idle detent. 

This condition, if not corrected, could 

result in undesired reverse thrust activation 

which, especially during approach, could 

result in reduced control of the aeroplane. 

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 July 26, 2010. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov. Follow the

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No. 2010– 

0093, dated May 20, 2010 (referred to 

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

unsafe condition for the specified 

products. The MCAI states: 

Reports have been received indicating that, 

if the power control friction wheel is 

tightened, the reverse thrust latch may stick 

and subsequently allow the Power Control 

Lever (PCL) to be inadvertently retarded aft 

of the idle detent. 

This condition, if not corrected, could 

result in undesired reverse thrust activation 

which, especially during approach, could 

result in reduced control of the aeroplane. 

For the reason described above, this AD 

requires an inspection of the PCL reverse 

thrust latch and the accomplishment of 

corrective actions as necessary. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

PILATUS AIRCRAFT LTD. has issued 

Service Bulletin No.: 76–002, dated 

October 15, 2009. 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 


cprice-sewell on DSK8KYBLC1PROD with PROPOSALS-1
32864 Federal Register / Vol. 75, No. 111 / Thursday, June 10, 2010 / Proposed Rules 

highlighted in a Note within the 

proposed AD. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 80 products of U.S. registry. 

We also estimate that it would take 

about 1 work-hour 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 $6,800, or $85 per 

product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 9 work-hours and require parts 

costing $100, for a cost of $865 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: 

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–2010– 

0583; Directorate Identifier 2010–CE– 

028–AD. 

Comments Due Date 

(a) We must receive comments by July 26, 

2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to PC–12/47E 

airplanes, manufacturer serial numbers 

(MSN) 1001 and MSN 1003 through 1140,

Subject 

(d) Air Transport Association of America 

(ATA) Code 76: Engine Controls. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

Reports have been received indicating that, 

if the power control friction wheel is 

tightened, the reverse thrust latch may stick 

and subsequently allow the Power Control 

Lever (PCL) to be inadvertently retarded aft 

of the idle detent. 

This condition, if not corrected, could 

result in undesired reverse thrust activation 

which, especially during approach, could 

result in reduced control of the aeroplane. 

For the reason described above, this AD 

requires an inspection of the PCL reverse 

thrust latch and the accomplishment of 

corrective actions as necessary. 

Actions and Compliance 

(f) Unless already done, do the following 

actions: 

(1) Within 30 days after the effective date 

of this AD, inspect the power control lever 

reverse thrust latch handle for free movement 

following the accomplishment instructions in 

paragraph 3.A. of PILATUS AIRCRAFT LTD. 

Service Bulletin No.: 76–002, dated October 

15, 2009. 

(2) If during the inspection required in 

paragraph (f)(1) of this AD you determine the 

reverse thrust latch sticks or the idle detent 

is not present, do the following actions: 

(i) Before further flight, insert Temporary 

Revision (TR) No. 12 to PC–12/47E Pilot’s 

Operating Handbook, dated October 15, 2009, 

into the normal procedures section of the 

aircraft flight manual (AFM). 

(ii) Within 12 months after the effective 

date of this AD, modify the engine control 

console assembly following the 

accomplishment instructions in paragraph 

3.B. of PILATUS AIRCRAFT LTD. Service 

Bulletin No.: 76–002, dated October 15, 2009. 

(iii) Before further flight after the 

modification required by paragraph (f)(2)(ii) 

of this AD, remove TR No. 12 to PC–12/47E 

Pilot’s Operating Handbook, dated October 

15, 2009, from the AFM. 

(3) If during the inspection specified in 

paragraph (f)(1) of this AD you determine the 

reverse thrust latch moves freely and the idle 

detent is present, no further action is 

required. 

FAA AD Differences 

Note: This AD differs from the MCAI and/ 

or service information as follows: No 

differences. 

Other FAA AD Provisions 

(g) The following provisions also apply to 

this AD:

received, and any final disposition, in 

person in the Federal Docket 

Management System Office (see 

ADDRESSES section for address and 

phone number) between 9 a.m. and 5 

p.m., Monday through Friday, except 

Federal holidays. An informal docket 

may also be examined during normal 

business hours at the office of the 

Alaska Flight Services Information Area 

Group. Persons interested in being 

placed on a mailing list for future 

NPRM’s should contact the FAA’s 

Office of Rulemaking, (202) 267–9677, 

to request a copy of Advisory Circular 

No. 11–2A, Notice of Proposed 

Rulemaking Distribution System, which 

describes the application procedure. 

The Proposal 

This action proposes to amend Title 

14 Code of Federal Regulations (14 CFR) 

part 71 by revising Class E airspace at 

Unalakleet, AK, to accommodate a new 

departure procedure, and new and 

amended SIAPs at Unalakleet Airport. 

This Class E airspace would provide 

adequate controlled airspace upward 

from the surface, and from 700 and 

1,200 feet above the surface for the 

safety and management of IFR 

operations at Unalakleet Airport. 

The Class E2 surface areas are 

published in paragraph 6002 in FAA 

Order 7400.9T, Airspace Designations 

and Reporting Points, signed August 27, 

2009, and effective September 15, 2009, 

which is incorporated by reference in 14 

CFR 71.1. The Class E airspace areas 

designated as 700/1200 foot transition 

areas are published in paragraph 6005 

in FAA Order 7400.9T, Airspace 

Designations and Reporting Points, 

signed August 27, 2009, and effective 

September 15, 2009, which is 

incorporated by reference in 14 CFR 

71.1. The Class E airspace designations 

listed in this document would be 

subsequently published in the Order. 

The FAA has determined that this 

proposed regulation only involves an 

established body of technical 

regulations for which frequent and 

routine amendments are necessary to 

keep them operationally current. It, 

therefore—(1) Is not a ‘‘significant 

regulatory action’’ under Executive 

Order 12866; (2) is not a ‘‘significant 

rule’’ under DOT Regulatory Policies 

and Procedures (44 FR 11034; February 

26, 1979); and (3) does not warrant 

preparation of a regulatory evaluation as 

the anticipated impact is so minimal. 

Because this is a routine matter that will 

only affect air traffic procedures and air 

navigation, it is certified that this rule, 

when promulgated, will not have a 

significant economic impact on a 

substantial number of small entities
