AGENCY: Federal Aviation 

Administration (FAA), Department of

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: 

Subsequent to accidents involving Fuel 

Tank System explosions in flight * * * and 

on ground, the FAA has published Special 

Federal Aviation Regulation 88 (SFAR88) 

* * * [which] required * * * [conducting] a 

design review against explosion risks. 

The unsafe condition is the potential 

of ignition sources inside fuel tanks, 

which, in combination with flammable 

fuel vapors, could result in fuel tank 

explosions 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 11, 2008. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of March 11, 2008.

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 December 10, 2007 (72 FR 

69628). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Subsequent to accidents involving Fuel 

Tank System explosions in flight * * * and 

on ground, the FAA has published Special 

Federal Aviation Regulation 88 (SFAR88) in 

June 2001. 

In their Letters referenced 04/00/02/07/01–

L296 dated March 4th, 2002 and 04/00/02/ 

07/03–L024, dated February 3rd, 2003, the 

JAA (Joint Aviation Authorities) 

recommended the application of a similar 

regulation to the National Aviation 

Authorities (NAA). 

Under this regulation, all holders of type 

certificates for passenger transport aircraft 

with either a passenger capacity of 30 or 

more, or a payload capacity of 7,500 pounds 

(3402 kg) or more, which have received their 

certification since January 1st, 1958, are 

required to conduct a design review against 

explosion risks. 

This Airworthiness Directive (AD), which 

renders mandatory the modification [6089] of 

improving the sealing of Fuel Access Doors, 

is a consequence of the design review. 

The unsafe condition is the potential of 

ignition sources inside fuel tanks, 

which, in combination with flammable 

fuel vapors, could result in fuel tank 

explosions and consequent loss of the 

airplane. Saab Modification 6089 

includes removing the fuel tank access 

doors and the old type of clamp rings 

and gaskets; installing new, improved 

clamp rings; re-installing the fuel tank 

access doors; and doing related 

investigative actions and applicable 

corrective actions. Related investigative 

actions and applicable corrective 

actions include inspecting for corrosion 

of the wing skin panel and access door 

areas, and, as applicable, replacing wear 

protection; contacting Saab and doing 

repairs if doubler flange is less than 

specified thickness; replacing any 

corroded or damaged foil panel; 

replacing any damaged sealing ring; 

removing corrosion from the wing skin 

panel; inspecting the access doors for 

damage and correct installation of the 

aluminum panel on the access door; 

and, as applicable, replacing the 

aluminum panel or the entire access 

door. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 


rmajette on PROD1PC64 with RULES
Federal Register / Vol. 73, No. 24 / Tuesday, February 5, 2008 / Rules and Regulations 6591 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

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 

about 6 products of U.S. registry. We 

also estimate that it will take about 130 

work-hours 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 $6,400 

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 

$100,800, or $16,800 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.

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing 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 distortion of the rudder 

bars due to rudder control forces during 

aerobatic operation and nose wheel 

steering reaction forces. Rudder bar 

distortion could result in reduced 

control or loss of control. This AD 

requires actions that are intended to 

address the unsafe condition described 

in the MCAI. 

DATES: This AD becomes effective 

March 11, 2008. 

As of March 11, 2008, the Director of

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 November 27, 2007 (72 FR 

66089) and proposed to supersede AD 

87–08–01, Amendment 39–5601, 

published in 1987 and AD 99–01–04, 

Amendment 39–10971, published in 

1999. That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states that rudder 

control forces during aerobatic 

operation and nose wheel steering 

reaction forces may cause rudder bar 

distortion. Rudder bar distortion could 

result in reduced control or loss of 

control. 

The MCAI requires you to replace the 

left and right rudder bars with 

reinforced rudder bars. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

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 FAA policies. 

Any such differences are highlighted in 

a NOTE within the AD. 

Costs of Compliance 

We estimate that this AD will affect 9 

products of U.S. registry. We also 

estimate that it will take about 3 workhours per product to comply with basic 

requirements of this AD. The average 

labor rate is $80 per work-hour. 

Required parts will cost about $657 per 

product. 

Based on these figures, we estimate 

the cost of this AD to the U.S. operators 

to be $8,073 or $897 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:
