ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Airbus Model A300 B2–1C, B2K–3C, 

B2–203, B4–2C, B4–103, and B4–203 

airplanes. This proposed AD was 

prompted by analysis that in a specific 

failure case of the upper primary 

attachment of the trimmable horizontal 

stabilizer actuator (THSA); the THSA 

upper secondary attachment would 

engage because it could only withstand 

the loads for a limited period of time. 

This proposed AD would require 

installation of three secondary retention 

plates for the gimbal bearings on the 

THSA upper primary attachment. We 

are proposing this AD to prevent failure 

of the secondary load path, which could 

result in loss of control of the airplane. 

DATES: We must receive comments on 

this proposed AD by March 22, 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 2011–0112, 

dated June 15, 2011 (referred to after 

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

condition for the specified products. 

The MCAI states: 

A specific failure case of the THSA 

[trimmable horizontal stabilizer actuator] 

upper primary attachment, which may result 

in a loading of the upper secondary 

attachment, has been identified by analysis. 

Primary load path failure can be caused by 

bearing migration from the upper attachment 

gimbal by failure or loss of a retention bolt. 

In case of failure of the THSA upper 

primary attachment, the THSA upper 

secondary attachment would engage. Because 

the upper attachment secondary load path 

can only withstand the loads for a limited 

period of time, the condition where it would 

be engaged could lead, if not detected and 

corrected, to the failure of the secondary load 

path, which would likely result in loss of 

control of the aeroplane. 

For the reasons explained above, this 

[EASA] AD requires installation of three 

secondary retention plates for the gimbal 

bearings on the THSA upper primary 

attachment. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Airbus has issued Mandatory Service 

Bulletin A300–27–0204, dated March 

11, 2011. 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 15 products of U.S. registry. 

We also estimate that it would take 

about 2 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 $6,541 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 

$100,665, or $6,711 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 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 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.

Airbus Model A300 series airplanes; all 

Model A300 B4–600, B4–600R, and F4– 

600R series airplanes, and Model C4– 

605R Variant F airplanes (collectively 

called A300–600 series airplanes). This 

proposed AD was prompted by reports 

of an inoperative fire shut-off valve 

(FSOV) as a result of damage due to 

over-length of the bonding lead. This 

proposed AD would require a one-time 

detailed inspection for length of the 

FSOV bonding leads and for contact or 

chafing of the wires, and corrective 

actions, if necessary. We are proposing 

this AD to detect and correct contact or 

chafing of wires and bonding leads 

which, if not detected could be a source 

of sparks in the wing trailing edge, and 

could lead to an uncontrolled engine 

fire.
