SUMMARY: This document publishes in 

the Federal Register an amendment 

adopting airworthiness directive (AD) 

2008–01–01 that was sent previously to 

all known U.S. owners and operators of 

certain Model 737–200, –300, –400, 

–500, –600, –700, –800, and –900 series 

airplanes; Model 747–400 series

replacing a certain flight deck door 

feature and revising the modification 

record placard. This AD is prompted by

flight deck door is defective. We are 

issuing this AD to prevent failure of this 

feature, which could jeopardize flight 

safety. 

DATES: This AD becomes effective July 

6, 2010 to all persons except those 

persons to whom it was made 

immediately effective by AD 2008–01– 

01, issued December 26, 2007, which 

contained the requirements of this 

amendment. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of July 6, 2010.

SUPPLEMENTARY INFORMATION: On 

December 26, 2007, we issued AD 2008– 

01–01, which applies to certain Model 

737–200, –300, –400, –500, –600, –700, 

–800, and –900 series airplanes; Model 

747–400 series airplanes; Model 757– 

200 and 757–300 series airplanes; 

Model 767–200, 767–300, and 767– 

400ER series airplanes; and Model 777– 

200 series airplanes. 

Background 

We have received a report indicating 

that a feature of the flight deck door is 

defective. This condition, if not 

corrected, could result in a failure of the 

feature, which could jeopardize flight 

safety. 

Relevant Service Information 

We reviewed the following service 

bulletins: 

TABLE—SERVICE BULLETINS

Jamco Service Bulletin— For Model— 

52–2295, Revision 1, dated October 10, 2007 ........................................ 737–200 –300, –400, –500, –600, –700, –800, and –900 series airplanes.

52–2305, Revision 1, dated October 10, 2007 ........................................ 777–200 series airplanes. 

The service bulletins describe 

procedures for replacing a certain flight 

deck door feature and revising the 

modification record placard. 

FAA’s Determination and Requirements 

of This AD 

Since the unsafe condition described 

is likely to exist or develop on other 

airplanes of these same type designs, we 

issued AD 2008–01–01 to prevent the 

failure of a certain feature of the flight 

deck door. The AD requires 

accomplishing the actions specified in 

the service information previously 

described. 

We found that notice and opportunity 

for prior public comment on AD 2008– 

01–01 were contrary to the public 

interest, and good cause existed to make 

the AD effective immediately by 

individual notices issued on December 

26, 2007, to all known U.S. owners and 

operators of certain Model 737–200, 

–300, –400, –500, –600, –700, –800, and 

–900 series airplanes; Model 747–400 

series airplanes; Model 757–200 and

200, 767–300, and 767–400ER series 

airplanes; and Model 777–200 series 

airplanes. These conditions still exist, 

and the AD is hereby published in the 

Federal Register as an amendment to 

section 39.13 of the Federal Aviation 

Regulations (14 CFR 39.13) to make it 

effective to all persons. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not provide you with notice and 

an opportunity to provide your 

comments before it becomes effective. 

However, we invite you to send any 

written data, views, or arguments about 

this AD. Send your comments to an 

address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2010–0638; Directorate Identifier 2007– 

NM–333–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this AD. We will consider all 

comments received by the closing date 

and may amend this AD because of 

those comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this AD. 

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 

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 that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

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. 

You can find our regulatory 

evaluation and the estimated costs of 

compliance in the AD Docket.

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: 

Two cases of a crack on a ‘‘dry’’ ADG [air 

driven generator] (Hamilton Sundstrand part 

number in the 761339 series), in the aft area 

of the strut and generator housing assembly, 

have been reported on CL–600–2B19 aircraft. 

The same part number is also installed on 

CL–600–2B16 (CL–604) aircraft. Investigation 

determined that the crack was in an area of 

the strut where the wall thickness of the 

casting was below specification, due to a 

manufacturing anomaly in a specific batch of 

ADGs. Structural failure and departure of the 

ADG during deployment could possibly 

result in damage to the aircraft structure. If 

deployment were activated by a dual engine 

shutdown, ADG structural failure would also 

result in loss of hydraulics for the flight 

controls. 

* * * * * 

The unsafe condition is possible loss of 

control of the airplane. We are issuing 

this AD to require actions to correct the 

unsafe condition on these products. 

DATES: This AD becomes effective 

August 5, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of August 5, 2010.

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 January 4, 2010 (75 FR 91). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

Two cases of a crack on a ‘‘dry’’ ADG [air 

driven generator] (Hamilton Sundstrand part 

number in the 761339 series), in the aft area 

of the strut and generator housing assembly, 

have been reported on CL–600–2B19 aircraft. 

The same part number is also installed on 

CL–600–2B16 (CL–604) aircraft. Investigation 

determined that the crack was in an area of 

the strut where the wall thickness of the 

casting was below specification, due to a 

manufacturing anomaly in a specific batch of 

ADGs. Structural failure and departure of the 

ADG during deployment could possibly 

result in damage to the aircraft structure. If 

deployment were activated by a dual engine 

shutdown, ADG structural failure would also 

result in loss of hydraulics for the flight 

controls. 

This directive gives instructions to check 

the part number of the installed ADG and, for 

ADGs with a part number in the 761339 

series, the serial numbers of the ADG and the 

strut and generator housing assembly are also 

to be checked. If these serial numbers are 

within specified ranges * * *, initial and
