AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Airbus Model A318–112, and –121; 

A319–111, –112, –115, –132, and –133; 

A320–214, –232, and –233; and A321– 

211, –212, –213, and –231 airplanes. 

This proposed AD was prompted by 

reports that some nuts installed on the 

wing, including on primary structural 

elements, were found cracked. This 

proposed AD would require inspecting 

to determine if certain nuts are installed 

or cracked, and replacing the affected 

nuts if necessary. We are proposing this 

AD to detect and correct missing and 

cracked nuts, which could result in the 

structural integrity of the airplane wings 

being impaired. 

DATES: We must receive comments on 

this proposed AD by May 7, 2012. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2011–0121R1, 

dated July 13, 2011 (referred to after this 

as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

During structural part assembly in Airbus 

production line, some [wing] nuts Part 

Number (P/N) ASNA2531–4 were found 

cracked. Investigations were performed to 

determine the batches of the affected nuts 

and had revealed that these nuts have been 

installed in production on the fuel tank area 

of aeroplanes listed in the applicability 

section of this AD. 

Static, fatigue and corrosion tests were 

performed, which demonstrated that no 

immediate maintenance action is necessary. 

However, a large number of these nuts are 

fitted on primary structural elements, which 

could have long-term consequences. 

This condition, if not corrected, could 

impair the structural integrity of the affected 

aeroplanes. 

For the reasons described above, this 

[EASA] AD requires a detailed inspection of 

the affected nuts [for cracking and to 

determine if nuts are installed], associated 

corrective actions, depending on findings, 

and replacement of the affected P/N 

ASNA2531–4 nuts with new ones, having the 


srobinson on DSK4SPTVN1PROD with PROPOSALS
Federal Register / Vol. 77, No. 55 / Wednesday, March 21, 2012 / Proposed Rules 16493 

same P/N [and reporting to Airbus the 

inspection results]. 

This [EASA] AD has been revised to reduce 

the Applicability. Since no spare nuts have 

been delivered to operators for installation on 

Airbus aeroplanes, only the Models and MSN 

listed in the Airbus SB are affected by this 

[EASA] AD. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Airbus has issued Service Bulletin 

A320–57–1153, including Appendices 

01, 02, and 03, Revision 01, dated June 

28, 2010. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of This 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 the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences Between This AD and the 

MCAI or Service Information 

This proposed AD differs from the 

MCAI and/or service information as 

follows: The European Aviation Safety 

Agency (EASA) Airworthiness Directive 

specifies a compliance time of 12 years 

after the first flight of the airplane. This 

proposed AD specifies a compliance 

time of the later of the following: (1) 

Within 6 years after the first flight of the 

airplane; or (2) within 6 years after the 

most recent scheduled fuel tank 

inspection or 6 months after the 

effective date of this AD (whichever 

occurs later). This difference has been 

coordinated with EASA. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 170 products of U.S. 

registry. We also estimate that it would 

take up to 15 work-hours 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 

$216,750, or $1,275 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 143 work-hours and require parts 

costing $0, for a cost of $12,155 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

(j) Other FAA AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, International 

Branch, ANM–116, Transport Airplane 

Directorate, FAA, has the authority to 

approve AMOCs for this AD, if requested 

using the procedures found in 14 CFR 39.19. 

In accordance with 14 CFR 39.19, send your 

request to your principal inspector or local 

Flight Standards District Office, as 

appropriate. If sending information directly 

to the International Branch, send it to ATTN:

collection of information displays a current 

valid OMB Control Number. The OMB 

Control Number for this information 

collection is 2120–0056. Public reporting for 

this collection of information is estimated to 

be approximately 5 minutes per response,
