Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 777–200 

and –300 series airplanes equipped with 

Rolls-Royce RB211 Trent 800 engines. 

This AD was prompted by reports of 

events related to thermal damage of the 

thrust reverser (T/R) inner wall on 

Rolls-Royce RB211 Trent 800 engines. 

This AD requires replacing the bleed 

valve parts and tubing with new parts 

and tubing on the left and right engines; 

and installing Aero-Engine database 

(AEDB) software in the airplane 

information management system (AIMS) 

hardware. We are issuing this AD to 

prevent T/R thermal damage caused by 

excessive heat downstream of the 8th 

stage IP8 exhaust ports, which could 

result in T/R structural failure. This 

failure could result in large pieces of the 

T/R or adjacent components departing 

the airplane. A separated T/R piece 

could result in a rejected takeoff and 

cause asymmetric thrust and consequent 

loss of control of the airplane during 

reverse thrust operations. Separated 

components could also cause structural 

damage to the airplane, damage to other 

airplanes due to debris left on the 

runway, or injury to people on the 

ground. 

DATES: This AD is effective October 3, 

2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of October 3, 2012.

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 published in the Federal 

Register on December 12, 2011 (76 FR 

77157). That NPRM proposed to require 

replacing bleed valve parts and tubing 

with new parts and tubing on the left 

and right Rolls-Royce RB211 Trent 800 

engines; and installing AEDB software 

in the airplane AIMS hardware. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal (76 FR 77157, 

December 12, 2011) and the FAA’s 

response to each comment. 

Request To Use Certain Service 

Information 

American Airlines (American) and 

Boeing requested that the NPRM (76 FR 

77157, December 12, 2011) allow the 

use of Boeing Special Attention Service 

Bulletin 777–31–0177, Revision 1, dated 

October 13, 2011, as a source of 

information to comply with the actions 

required by paragraph (h) of the NPRM. 

We agree. Paragraph (h) of the NPRM 

(76 FR 77157, December 12, 2011) 

specified the use of Boeing Special 

Attention Service Bulletin 777–31– 

0177, dated September 23, 2010. We 

have revised paragraph (h) of the final 

rule to add Boeing Special Attention 

Service Bulletin 777–31–0177, Revision 

1, dated October 13, 2011, as an 

additional source of service information 

for accomplishing the actions specified 

in that paragraph. Boeing Special 

Attention Service Bulletin 777–31– 

0177, Revision 1, dated October 13, 

2011, specifies updates to the 

concurrent requirements paragraph. 

Request To Allow Use of Service 

Information Revision 

American requested that the NPRM 

(76 FR 77157, December 12, 2011) allow 

the use of Rolls-Royce Service Bulletin 

RB.211–75–G466, dated November 21, 

2011, as an additional source of 

information to accomplish the 

requirements of paragraph (g) of the 

NPRM. 

We agree. We have changed the final 

rule to specify that the actions required 

by paragraph (g) of the AD may be done 

in accordance with the Accomplishment 

Instructions of Rolls-Royce Service 

Bulletin RB.211–75–G466, Revision 1, 

including Supplement, dated June 20, 

2011; or Rolls-Royce Service Bulletin 

RB.211–75–G466, Revision 2, including 

Supplement, dated November 21, 2011.

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (76 FR 

77157, December 12, 2011) for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (76 FR 77157, 

December 12, 2011). 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of the AD. 

Costs of Compliance 

We estimate that this AD affects 55 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Replacement ................................................... 16 work-hours × $85 per hour = $1,360 ........ $75,000 $76,360 $4,199,800 

Installation of AEDB software ......................... 1 work-hour × $85 per hour = $85 ................. 0 85 4,675 

According to the manufacturer, some 

of the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected individuals. We 

do not control warranty coverage for 

affected individuals. As a result, we 

have included all costs in our cost 

estimate. 

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), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) 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.

Airworthiness Directives; Goodyear 

Aviation Tires 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for 

Goodyear Aviation Tires, part number 

299K63–1 (Brazilian made new tires 

only), installed on various transport 

category airplanes, including but not 

limited to Bombardier, Inc. Model CL– 

600–2B19 airplanes. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued by the aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as tire tread separations and 

tread-area bulges on the main landing 

gear tires due to low adhesion in the 

tread shoulder area. The unsafe 

condition is specific to Brazilian 

produced new tires, size H29x9.0–15, 

only; retread tires are not affected by 

this AD. This condition, if not detected 

and corrected, could cause the main 

landing gear tires to fail during takeoff 

or landing. The failure may cause 

damage to the airplane structure, flaps, 

engine, and wheel well and result in 

reduced controllability of the airplane. 

We are issuing this AD to require 

actions to address the unsafe condition 

on these products. 

DATES: This AD is effective September 

13, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of September 13, 2012. 

We must receive comments on this 

AD by October 15, 2012.
