ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) 

that applies to the products listed above. 

This 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: 

Two cases of main landing gear collapse 

had been reported. Main landing gear 

collapse may result in unsafe landing of the 

aircraft. 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

October 18, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of October 18, 2011.

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 March 8, 2011 (76 FR 

12629), and proposed to supersede AD 

2007–22–09, Amendment 39–15245 (72 

FR 61288, October 30, 2007). That 

NPRM proposed to correct an unsafe 

condition for the specified products. 

The MCAI states: 

Two cases of main landing gear collapse 

had been reported. Main landing gear 

collapse may result in unsafe landing of the 

aircraft. 

Revision 1 of this directive amended the 

time compliance in paragraph C.2 (3 months 

in addition to 500 hours air time), to add new 

paragraph C.3 to cater for retract actuator 

which has accumulated less than 4,000 

landings or 2 years since new and to add new 

paragraphs B.2 and C.4 to require that the 

respective inspections be repetitively 

performed until terminating action becomes 

available. 

Revision 2 of this directive amends the 

detailed visual inspection requirement in 

paragraph C.3 to include the main landing 

gear retract actuator, part number 46550–11, 

and to add new paragraph F to mandate the 

incorporation of main landing gear retract 

actuator part number, 46550–13 as the 

terminating action and to add new paragraph 

G for the maintenance requirement. 

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 (76 

FR 12629, March 8, 2011) or on the 

determination of the cost to the public. 

Change Made to This AD 

We have removed paragraph 

(v)(3)(i)(D) of the NPRM (76 FR 12629, 

March 8, 2011) from this AD, and 

reidentified subsequent paragraphs 

accordingly. 

Conclusion 

We reviewed the available data, and 

determined that air safety and the 

public interest require adopting the AD 

with the change described previously. 

We determined that this change will not 

increase the economic burden on any 

operator or increase the scope of the AD. 

Differences Between This 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 required different 

actions in this AD from those in the 

MCAI in order to follow our FAA 

mstockstill on DSK4VPTVN1PROD with RULES

Federal Register / Vol. 76, No. 177 / Tuesday, September 13, 2011 / Rules and Regulations 56291 

policies. Any such differences are 

highlighted in a Note within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

about 55 products of U.S. registry. 

The actions that are required by AD 

2007–22–09, Amendment 39–15245 (72 

FR 61288, October 30, 2007), and 

retained in this AD take about 5 workhours per product, at an average labor 

rate of $85 per work-hour. Based on 

these figures, the estimated cost of the 

currently required actions is $425 per 

product. 

We estimate that it will take about 8 

work-hours per product to comply with 

the new basic requirements of this AD. 

The average labor rate is $85 per workhour. Required parts will cost about 

$27,511 per product. Where the service 

information lists required parts costs 

that are covered under warranty, we 

have assumed that there will be no 

charge for these parts. As we do not 

control warranty coverage for affected 

parties, some parties may incur costs 

higher than estimated here. Based on 

these figures, we estimate the cost of 

this AD to the U.S. operators to be 

$1,550,505, or $28,191 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); 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 AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains the NPRM (76 FR 12629, 

March 8, 2011), the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is in the ADDRESSES

section. Comments will be available in 

the AD docket shortly after receipt.

approval letter must specifically reference 

this AD. AMOCs approved previously in 

accordance with AD 2007–22–09, 

Amendment 39–15245 (72 FR 61288, October 

30, 2007), are approved as AMOCs for the 

corresponding provisions of paragraph (i) 

and (j) of this AD. 

(2) Airworthy Product: For any 

requirement in this AD to obtain corrective 

actions from a manufacturer or other source, 

use these actions if they are FAA-approved. 

Corrective actions are considered FAAapproved if they are approved by the State 

of Design Authority (or their delegated 

agent). You are required to assure the product 

is airworthy before it is returned to service. 

(3) Special Flight Permits: Special flight 

permits may be issued in accordance with 

sections 21.197 and 21.199 of the Federal 

Aviation Regulations (14 CFR 21.197 and 

21.199) to operate the airplane to a location 

where the airplane can be inspected (if the 

operator elects to do so), provided that the 

procedures and limitations in paragraphs 

(v)(3)(i) and (v)(3)(ii) of this AD are adhered 

to. 

(i) Flight Crew Limitations and Procedures: 

(A) Ferry flight with gear extended and 

pinned;
