ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above that would 

supersede an existing AD. This 

proposed 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: 

Prompted by a reported in-service event, 

EASA issued AD 2009–0084 to prevent 

unwanted movement of pilot- or co-pilot seat 

in the horizontal direction which is 

considered as potentially unsafe, especially 

during the takeoff phase when the speed of 

the aeroplane is greater than 100 knots and 

until landing gear retraction. 

* * * * * 

Uncommanded movement of the pilot 

and co-pilot seats during takeoff or 

landing could interfere with the 

operation of the airplane and, as a 

result, could cause loss of control of the 

airplane. The proposed AD would 

require actions that are intended to 

address the unsafe condition described 

in the MCAI. 

DATES: We must receive comments on 

this proposed AD by January 18, 2011.

about this proposed AD. 

Discussion 

On May 15, 2009, we issued AD 

2009–11–09, Amendment 39–15919 (74 

FR 25399, May 28, 2009). That AD 

required actions intended to address an 

unsafe condition on the products listed 

above. 

Since we issued AD 2009–11–09, the 

European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2010–0070, 

dated April 14, 2010 (referred to after 

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

condition for the specified products. 

The MCAI states: 

Prompted by a reported in-service event, 

EASA issued AD 2009–0084 [which 

corresponds to FAA AD 2009–11–09] to 

prevent unwanted movement of pilot- or copilot seat in the horizontal direction which 

is considered as potentially unsafe, 

especially during the takeoff phase when the 

speed of the aeroplane is greater than 100 

knots and until landing gear retraction. 

AD 2009–0084 required the deactivation of 

the electrical power of SOGERMA pilot seats 

P/N 2510112 series and co-pilot seats P/N 

2510113 series. Optional intermediate 

actions were also provided by AD 2009–0084 

to allow partial or full restoration of seat 

adjustment functionality. 

Since AD 2009–0084 was issued, a 

permanent solution has been developed that 

terminates the de-activation requirement and 

invalidates the intermediate actions. 

Consequently, this AD retains 

requirements of EASA AD 2009–0084, which 

is superseded, and requires implementing the 

terminating action. In addition, this AD 

prohibits the (re)installation of unmodified 

pilot- and co-pilot seats on any aeroplane 

that has been modified in accordance with 

the requirements of this AD. 

Uncommanded movement of the pilot 

and co-pilot seats during takeoff or 

landing could interfere with the 

operation of the airplane and, as a 

result, could cause loss of control of the 

airplane. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Relevant Service Information 

Airbus has issued the service 

information specified in the following 

table. 

TABLE—SERVICE INFORMATION

Document Revision Date 

Airbus Mandatory Service Bulletin A300–25–6217 ....................................................... Original ........................................ August 31, 2009. 

Airbus Mandatory Service Bulletin A310–25–2205 ....................................................... Original ........................................ August 31, 2009. 

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 

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 proposed 

different actions in this AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

highlighted in a NOTE within the 

proposed AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 132 products of U.S. 

registry. 

The actions that are required by AD 

2009–11–09 and retained in this 

proposed AD take about 2 work-hours 

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 $170 per 

product. 

We estimate that it would take about 

2 work-hours per product to comply 

with the new basic requirements of this 

proposed AD. The average labor rate is 

$85 per work-hour. Required parts 

would cost about $5,000 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 costs. 

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 $704,880, or $5,340 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. 


jlentini on DSKJ8SOYB1PROD with PROPOSALS
Federal Register / Vol. 75, No. 230 / Wednesday, December 1, 2010 / Proposed Rules 74667 

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 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 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference,

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Model 777–200, –200LR, –300, and 

–300ER series airplanes. This proposed 

AD would require repetitive detailed 

inspections for disbonding and tearing 

and measurements for wear of the 

internal diameter (ID) of the Karon-lined 

bushings of the bulkhead support 

jackscrew fitting and of the jackscrew 

fitting of the horizontal stabilizer; 

repetitive installations of the horizontal 

stabilizer trim actuator (HSTA); and if 

necessary, replacement of the bushings 

with new bushings and all applicable 

related investigative and corrective 

actions. This proposed AD results from 

a report indicating that a Karon-lined 

bushing with the liner broken into five 

pieces was found during a scheduled 

inspection of the HSTA components; 

the broken liner had worn and 

disbonded from the bushing. We are 

proposing this AD to detect and correct 

discrepancies of the HSTA attachment 

locations, which could result in reduced 

structural integrity of the horizontal 

stabilizer and consequent loss of 

controllability of the airplane. 

DATES: We must receive comments on 

this proposed AD by January 18, 2011.
