This AD results from a determination of 

insufficient clearance and subsequent 

interference between the oil scavenge 

tube on the turbine rear frame of the 

engine and the bolt on the aft cowl 

insulation blanket of the thrust reverser. 

We are issuing this AD to prevent 

damage and possible puncture of the oil 

scavenge tube and consequent oil loss, 

which could result in an in-flight 

shutdown of the engine.

SUPPLEMENTARY INFORMATION: 

Discussion 

Boeing has determined that 

insufficient clearance and subsequent 

interference exists between the oil 

scavenge tube on the turbine rear frame 

of the engine and the bolt on the aft 

cowl insulation blanket. This location 

could encounter interference under 

flight loads. Damage to the oil scavenge 

tube was confirmed after flight on 

undelivered airplanes. Several inservice airplanes had sustained damage 

(dents, gouges, or chafing) because of 

the interference condition. This 

condition, if not corrected, could result 

in possible puncture of the oil scavenge 

tube and consequent oil loss, resulting 

in an in-flight shutdown of the engine. 

Relevant Service Information 

We reviewed Boeing Alert Service 

Bulletin 777–78A0070, dated November 

20, 2008. This service bulletin describes 


erowe on DSK5CLS3C1PROD with RULES
49376 Federal Register / Vol. 75, No. 156 / Friday, August 13, 2010 / Rules and Regulations 

procedures for replacing the insulation 

blanket fasteners of the lower aft cowl 

of the thrust reverser. 

Boeing Alert Service Bulletin 777– 

78A0070, dated November 20, 2008, 

specifies prior or concurrent 

accomplishment of an inspection of the 

oil scavenge tube on the turbine rear 

frame of the engine for damage, and 

replacement if damage is found, in 

accordance with General Electric GE90– 

100 Service Bulletin 79–0017, dated 

March 3, 2008. 

FAA’s Determination and Requirements 

of This AD 

No airplanes affected by this AD are 

on the U.S. Register. We are issuing this 

AD because the unsafe condition 

described previously is likely to exist or 

develop on other products of the same 

type design that could be registered in 

the United States in the future. This AD 

requires replacing the insulation blanket 

fasteners of the lower aft cowl of the 

thrust reverser. This AD also requires 

inspecting the oil scavenge tube on the 

turbine rear frame of the engine for 

damage, and replacement if necessary. 

Since no airplanes are affected by this 

AD, notice and opportunity for public 

comment before issuing this AD are 

unnecessary. 

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– 

2010–0704; Directorate Identifier 2010– 

NM–037–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.

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: 

A potential fleet wide problem has been 

identified regarding the interchanging of 

wing links on all BAe 146 & AVRO 146–RJ 

aircraft during scheduled maintenance. Some 

operators erroneously believed that these 

parts were interchangeable. The effects of 

changing winglinks has resulted in either a 

shorter or longer wing link being fitted, 

which introduces local stresses in the wing 

top and bottom surfaces local to rib 2, wing 

links and wing link fitting attachment and 

the fuselage local to Frames 26 and 29. This 

condition, if not corrected, could result in a 

reduction of structural integrity of the 

fuselage/wing attachment with possible 

catastrophic consequences. 

* * * * * 

The unsafe condition could result in 

loss of a wing or controllability of the 

airplane. We are issuing this AD to 

require actions to correct the unsafe 

condition on these products. 

DATES: This AD becomes effective 

September 17, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of September 17, 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 March 15, 2010 (75 FR 

12158). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

A potential fleet wide problem has been 

identified regarding the interchanging of 

wing links on all BAe 146 & AVRO 146–RJ 

aircraft during scheduled maintenance. Some 

operators erroneously believed that these 

parts were interchangeable. The effects of 

changing winglinks has resulted in either a 

shorter or longer wing link being fitted, 

which introduces local stresses in the wing 

top and bottom surfaces local to rib 2, wing 

links and wing link fitting attachment and 

the fuselage local to Frames 26 and 29. This 

condition, if not corrected, could result in a 

reduction of structural integrity of the 

fuselage/wing attachment with possible 

catastrophic consequences. 

For the reasons described above, the 

present Airworthiness Directive (AD) 

requires the accomplishment of inspections 

and rectification actions, as necessary. 

The unsafe condition could result in 

loss of a wing or controllability of the 

airplane. The inspections include 

inspecting wing links for incorrect part 

numbers (i.e., parts that are not 

original), inspecting to determine wing 

geometry measurements, and inspecting 

the wing link, bores, bolts, and nuts for 

corrosion. Corrective actions include 

installing wing-to-fuselage fairings and 

repairing. 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. 

Explanation of Change to Applicability 

We have revised the applicability in 

paragraph (c) of this final rule to 

identify model designations as 

published in the most recent type 

certificate data sheet for the affected 

models. 

Conclusion 

We reviewed the available data 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
