Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

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: 

Airbus: Docket No. FAA–2012–1159; 

Directorate Identifier 2012–NM–028–AD. 

(a) Comments Due Date 

We must receive comments by December 

24, 2012. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Airbus Model A310– 

203, –204, –222, –304, –322, and –324 

airplanes, certificated in any category, 

manufacturer serial numbers 0378, 0392, 

0399, 0404, 0406, 0407, 0409, 0410, 0412, 

0413, 0416, 0418, 0419, 0421, 0422, 0424, 

0425, 0427, 0428, 0429, 0431, 0432, 0434 to 

0437 inclusive, 0439, 0440, 0441, 0443 to 

0449 inclusive, 0451 to 0454 inclusive, 0456, 

0457, 0458, 0467, 0472, 0473, 0475, 0476,

Airworthiness Directives; Airbus 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Model A330–200, –300 and –200 

Freighter series airplanes; and all Model 

A340–200 and –300 series airplanes. 

This proposed AD was prompted by a 

determination that the bonding lead 

from a certain isolation valve to a frame 

was too close to an electrical harness, 

which might cause chafing between the 

electrical harness and the associated 

bonding lead. This chafing could lead to 

a short circuit of the isolation valve and 

consequent non-closure of the isolation 

valve, which would prevent the air-flow 

to be shut-off in case of fire. This 

proposed AD would require modifying 

the bonding lead installation of the 

isolation valve. We are proposing this 

AD to prevent such chafing, which 

could result in non-closure of the 

isolation valve in the event of a fire and 

consequent damage to the airplane and 

injury to its occupants. 

DATES: We must receive comments on 

this proposed AD by December 24, 

2012.

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 2012–0090, 

dated May 22, 2012 (referred to after 

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

condition for the specified products. 

The MCAI states: 

It was noticed in production that the 

bonding lead from the isolation valve 283HN 

to Frame (FR) 64, between Stringer (STGR) 33 

and STGR 34, was too close to the electrical 

harness 5871VB. The results of the technical 

investigations carried out by Airbus 

determined that this insufficient clearance 

may cause chafing between the electrical 

harness 5871VB and the associated bonding 

lead. 

This condition, if not corrected, could lead 

to a short circuit of the isolation valve and 

consequent non-closure of the isolation valve 

283HN, which would prevent the air flow to 

be shut-off in case of fire, potentially 

resulting in damage to the aeroplane and 

injury to its occupants. 

For the reasons described above, this 

[EASA] AD requires the installation of a new 

bonding bracket and new bonding lead at 

STGR33, between FR64 and FR65 introduced 

by Airbus modification (mod.) 201500, or 

mod. 201681 in production, or Airbus 

Service Bulletin (SB) A330–21–3165, SB 

A330–21–3160 or SB A340–21–4152 in 

service. 

In addition, for aeroplanes already 

modified in accordance with the instructions 

of Airbus SB A330–21–3165 or SB A340–21– 

4152 at original issue or Revision 01, it [this 

EASA AD] requires accomplishment of the 

additional work (additional wiring connected 

to the structure of the aeroplane). 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Airbus has issued the following 

service bulletins: 

• Mandatory Service Bulletin A330– 

21–3160, dated August 4, 2011. 

• Mandatory Service Bulletin A330– 

21–3165 Revision 02, dated March 29, 

2012. 

• Mandatory Service Bulletin A340– 

21–4152, Revision 02, dated March 29, 

2012. 

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. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 58 products of U.S. registry. 

We also estimate that it would take 

about 6 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $66 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 the proposed AD on U.S. 

operators to be $33,408, or $576 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.

66766 Federal Register / Vol. 77, No. 216 / Wednesday, November 7, 2012 / Proposed Rules 

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. 

List of Subjects in 14 CFR Part 39

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:
