Airworthiness Directives; Airbus Model 

A300–600 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This 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: 

One operator experienced failures of four 

Fuel Level Sensor-Amplifier (FLSA) and 

Multi Tank Indicators (MTI) units. FLSA and 

MTI failures have been identified as having 

been caused by incorrect connector sleeves 

material fitted to the MTI units. 

Degradation of the electrical insulation 

sleeves of the Low-level indication lamps on 

the MTI on the flight deck can cause a short 

circuit that might result in high voltage being 

conveyed to the high and low level sensors 

in the outer tanks. This might cause the level 

sensor to heat above acceptable limits. 

* * * * * 

This action is necessary to prevent 

overheating of the fuel level sensors, 

which could result in a fuel tank 

explosion and consequent loss of the 

airplane. We are issuing this AD to 

require actions to correct the unsafe 

condition on these products. 

DATES: This AD becomes effective 

March 27, 2009. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of March 27, 2009.

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 June 6, 2008 (73 FR 32250). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

One operator experienced failures of four 

Fuel Level Sensor-Amplifier (FLSA) and 

Multi Tank Indicators (MTI) units. FLSA and 

MTI failures have been identified as having 

been caused by incorrect connector sleeves 

material fitted to the MTI units. 

Degradation of the electrical insulation 

sleeves of the Low-level indication lamps on 

the MTI on the flight deck can cause a short 

circuit that might result in high voltage being 

conveyed to the high and low level sensors 

in the outer tanks. This might cause the level 

sensor to heat above acceptable limits. 

For the reasons stated above, this 

Airworthiness Directive (AD) requires the 

accomplishment of wiring modifications to 

protect the FLSA and the Flight Warning 

Computers from 115V AC and 28V DC short 

circuits within the MTI. 

This action is necessary to prevent 

overheating of the fuel level sensors, 

which could result in a fuel tank 

explosion and consequent loss of the 

airplane. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Actions Since NPRM Was Issued 

Since we issued the NPRM, Airbus 

has issued Mandatory Service Bulletin 

A300–28A6096, Revision 02, dated July 

4, 2008. In the NPRM, we referred to 

Airbus Mandatory Service Bulletin 

A300–28A6096, Revision 01, dated 

April 16, 2008, as the source of service 

information for doing the modification. 

The procedures in Airbus Mandatory 

Service Bulletin A300–28A6096, 

Revision 02, dated July 4, 2008, are 

essentially the same as those in Airbus 

Mandatory Service Bulletin A300– 

28A6096, Revision 01, dated April 16, 

2008. Therefore, we have revised 

paragraph (f) of this AD to refer to 

Airbus Mandatory Service Bulletin 

A300–28A6096, Revision 02, dated July 

4, 2008, as the appropriate source of 

service information for doing the 

modification, and to give credit for 

using Airbus Mandatory Service 

Bulletin A300–28A6096, Revision 01, 

dated April 16, 2008, for accomplishing 

the modification before the effective 

date of the AD. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received. 

Request To Delay Issuance of AD 

Air Transport Association (ATA), on 

behalf of its member American Airlines 

(AA), and UPS and FedEx ask that we 

delay issuance of the AD until the 

master minimum equipment list 

(MMEL) can be revised to support the 

low-level warning configuration. AA, 

UPS, and FedEx state that disconnection 

of the low-level warning for the left and 

right outer fuel tanks requires 

significant changes to the Airbus A300– 

600 MMEL. AA, UPS, and FedEx add 

that the current MMEL available to U.S. 

operators cannot support the 

disconnected low-level warning 

configuration; therefore, the AD should 

not be released until the MMEL has 

been revised. 

We disagree with the commenter’s 

request and rationale for delaying 

issuance of the AD. Revision 16 of the 

MMEL, dated October 2008, has been 

released and is available to U.S. 

operators. Revision 16 of the MMEL 

supports the low-level warning 

Federal Register / Vol. 74, No. 33 / Friday, February 20, 2009 / Rules and Regulations 7793 

configuration. Therefore, we have made 

no change to the AD in this regard. 

Request To Extend Compliance Time 

ATA, on behalf of its member AA, 

and UPS and FedEx ask that we revise 

the compliance time specified in the 

NPRM from 90 to 180 days to allow 

FAA approval of the air carrier’s 

customized MEL after it has been 

revised, and to facilitate distribution. 

We disagree with the commenters. As 

stated above, the revised MMEL has 

been released and is available to air 

carriers. We have determined that the 3- 

month compliance time specified in this 

AD is adequate to address the unsafe 

condition in a timely manner. We have 

made no change to the AD in this 

regard. 

Request To Include Alternate 

Terminating Action 

ATA on behalf of its member AA, and 

UPS and FedEx ask that the AD include 

alternative terminating action for 

operators that install multi-task 

indicators (MTIs) that have been 

modified per Smiths Service Bulletin 

1410KID–28–468, and installed per 

Airbus Mandatory Service Bulletin 

A300–28–6101, dated June 4, 2008. AA 

and FedEx state that once the MTI is 

modified the unsafe condition specified 

in the NPRM will be addressed. UPS 

states that the improved sleeve installed 

per Airbus Mandatory Service Bulletin 

A300–28–6101, dated June 4, 2008, 

addresses the concerns in the NPRM. 

We disagree with the commenters. 

Based on information provided by 

Airbus, Airbus Mandatory Service 

Bulletin A300–28–6101, dated June 4, 

2008, does not contain a final fix for the 

unsafe condition specified in the AD. 

Airbus is currently developing two 

modifications that provide the final 

solution to address the unsafe condition 

identified in this AD. Once these 

modifications are developed, approved, 

and available, we might consider 

additional rulemaking which would 

terminate the AD requirements. We 

have made no change to the AD in this 

regard. 

Conclusion 

We reviewed the available data, 

including the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the change described previously. 

We determined that this change will not 

increase the economic burden on any 

operator or increase the scope of the AD. 

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 required different 

actions in this AD from those in the 

MCAI in order to follow our FAA 

policies. Any such differences are 

highlighted in a NOTE within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

151 products of U.S. registry. We also 

estimate that it will take about 5 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $80 per work-hour. 

Required parts will cost about $0 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 $60,400, or 

$400 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 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); 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 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, 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.

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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: 

2009–02–04 Airbus: Amendment 39–15794. 

FAA–2008–0613; Directorate Identifier 

2008–NM–066–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective March 27, 2009. 

Affected ADs 

(b) None. 

7794 Federal Register / Vol. 74, No. 33 / Friday, February 20, 2009 / Rules and Regulations 

Applicability 

(c) This AD applies to all Airbus Model 

A300–600 airplanes, certificated in any 

category; all certified models, all serial 

numbers. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 28: Fuel. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

One operator experienced failures of four 

Fuel Level Sensor-Amplifier (FLSA) and 

Multi Tank Indicators (MTI) units. FLSA and 

MTI failures have been identified as having 

been caused by incorrect connector sleeves 

material fitted to the MTI units. 

Degradation of the electrical insulation 

sleeves of the Low-level indication lamps on 

the MTI on the flight deck can cause a short 

circuit that might result in high voltage being 

conveyed to the high and low level sensors 

in the outer tanks. This might cause the level 

sensor to heat above acceptable limits. 

For the reasons stated above, this 

Airworthiness Directive (AD) requires the 

accomplishment of wiring modifications to 

protect the FLSA and the Flight Warning 

Computers from 115V AC and 28V DC short 

circuits within the MTI. 

This action is necessary to prevent 

overheating of the fuel level sensors, which 

could result in a fuel tank explosion and 

consequent loss of the airplane. 

Actions and Compliance 

(f) Unless already done, within 3 months 

after the effective date of this AD: Modify the 

wiring in the right-hand electronics rack in 

accordance with the Accomplishment 

Instructions of Airbus Mandatory Service 

Bulletin A300–28A6096, Revision 02, dated 

July 4, 2008. Previous accomplishment of the 

modification before the effective date of this 

AD in accordance with Airbus Mandatory 

Service Bulletin A300–28A6096, dated 

October 19, 2007; or Revision 01, dated April 

16, 2008; meets the requirements in this 

paragraph.

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued 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: 

PW206 and PW207 compressor turbine 

(CT) disc bore areas may experience impact 

damage resulting from bending or fracture of 

the CT disc retaining nut. Damage of the CT 

disc bore area can reduce LCF capabilities of 

the CT disc, resulting in disc fracture. 

We are issuing this AD to prevent 

damage to the CT disc bore area, which 

could result in possible uncontained 

failure of the engine and damage to the 

helicopter. 

DATES: This AD becomes effective 

March 27, 2009. The Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications listed in this AD as of
