AGENCY: Federal Aviation 

Administration (FAA), Department of

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Airbus Model A330–200 freighter series 

airplanes; Model A330–200 and –300 

series airplanes; and Model A340–200 

and –300 series airplanes. This AD was 

prompted by a report of corrosion found 

on the main fitting of the nose landing 

gear (NLG) leg in the vicinity of the 

dowel pin bushes retaining the lower 

steering flange. This AD requires 

modifying the NLG main fitting by 

adding primer paint to the cadmium 

around the dowel bush holes. We are 

issuing this AD to prevent NLG main 

fitting rupture, which could result in an 

NLG collapse. 

DATES: This AD becomes effective June 

21, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of June 21, 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 December 29, 2011 (76 FR 

81884). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Corrosion has been found on the main 

fitting of the NLG leg in the vicinity of the 

dowel pin bushes retaining the lower steering 

flange on A330/A340 aeroplanes. The 

majority of parts have been reworked and 

returned to service. 

This corrosion, if not avoided, could lead 

to the NLG main fitting rupture, possibly 

resulting in a NLG collapse, which would 

constitute an unsafe condition. 

In order to maintain the structural integrity 

of the NLG, this [EASA] AD requires the 

accomplishment of a modification which 

consists in adding primer paint to the 

cadmium around the dowel bush holes on 

the main fitting, in order to provide further 

protection against cadmium degradation. 

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 81884, December 29, 2011) or on the 

determination of the cost to the public. 


srobinson on DSK4SPTVN1PROD with RULES
Federal Register / Vol. 77, No. 96 / Thursday, May 17, 2012 / Rules and Regulations 29211 

Changes to the AD 

Airbus has issued Mandatory Service 

Bulletins A330–32–3241 and A340–32– 

4282, both Revision 01, both including 

Appendix 01, both dated October 6, 

2011, which correct certain aircraft 

maintenance manual references. We 

referred to Airbus Mandatory Service 

Bulletins A330–32–3241 and A340–32– 

4282, both dated November 26, 2010, as 

the appropriate sources of service 

information for doing the actions 

specified in the NPRM (76 FR 81884, 

December 29, 2011). We have updated 

paragraphs (g) and (j) of this AD to refer 

to Airbus Mandatory Service Bulletins 

A330–32–3241 and A340–32–4282, both 

Revision 01, both including Appendix 

01, both dated October 6, 2011. We have 

also added new paragraph (h) to this AD 

to give credit for actions done before the 

effective date of this AD in accordance 

with Airbus Mandatory Service 

Bulletins A330–32–3241 and A340–32– 

4282, both dated November 26, 2010, 

and updated subsequent paragraph 

identifiers accordingly. 

We also added a reference to Model 

A330–200 freighter series airplanes in 

paragraphs (g) and (h) of this AD. 

Conclusion 

We reviewed the available data 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 changes: 

• Are consistent with the intent that 

was proposed in the NPRM (76 FR 

81884, December 29, 2011) for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (76 FR 81884, 

December 29, 2011). 

Costs of Compliance 

We estimate that this AD will affect 

55 products of U.S. registry. We also 

estimate that it will take about 66 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 $10,000 

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 

$858,550, or $15,610 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 that 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. 

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 81884, 

December 29, 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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 777 

airplanes. This AD was prompted by 

reports of fractured and missing latch 

pin retention bolts that secure the latch 

pins on the forward cargo door. This AD 

requires repetitive detailed inspections 

for fractured or missing latch pin 

retention bolts, replacement of existing 

titanium bolts with new Inconel bolts, 

and related investigative and corrective 

actions if necessary. We are issuing this 

AD to detect and correct fractured and 

missing latch pin retention bolts, which 

could result in potential separation of 

the cargo door from the airplane and 

catastrophic decompression of the 

airplane. 

DATES: This AD is effective June 21, 

2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of June 21, 2012.
