AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Boeing Model 757–200, –200CB, and 

–300 series airplanes. This AD requires 

a detailed inspection for damage of the 

wire bundle of the right recirculation 

fan, and repair if necessary. This AD 

also requires re-routing the wire bundle 

of the right recirculation fan. This AD 

results from a report indicating that, 

during landing of a Model 757 airplane, 

an overheat warning and smoke 

occurred in the main cabin, and the 

right recirculation fan stopped 

operating. We are issuing this AD to 

prevent damage of the wiring bundle of 

the right recirculation fan. Such damage 

could result in a short circuit and 

possible fire in the mix bay or smoke in 

the main cabin. 

DATES: This AD is effective July 16, 

2009. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of July 16, 2009.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an airworthiness 

directive (AD) that would apply to 

certain Boeing Model 757–200, –200CB, 

and –300 series airplanes. That NPRM 

was published in the Federal Register 

on August 31, 2007 (72 FR 50290). That 

NPRM proposed to require a detailed 

inspection for damage of the wire 

bundle of the right recirculation fan, 

and repair if necessary. That NPRM also 

proposed to require re-routing the wire 

bundle of the right recirculation fan. 

Actions Since the NPRM Was Issued 

The NPRM referred to Boeing Service 

Bulletin 757–21–0109, dated December 

15, 2006, as the appropriate source of 

service information for the proposed 

actions. Boeing has since revised that 

service bulletin. Boeing Service Bulletin 

757–21–0109, Revision 1, dated October 

30, 2008, clarifies certain procedures 

but otherwise adds no new actions. We 

have revised paragraphs (c) and (f) in 

this final rule to refer to Revision 1 of 

the service bulletin. We have added a 

new paragraph (g) to this final rule to 

provide credit for actions done before 

the effective date of the AD in 

accordance with the original service 

bulletin. We have renumbered 

subsequent paragraphs accordingly. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received from 

the two commenters. 

Support for the NPRM 

Boeing concurs with the contents of 

the NPRM. 

Request To Clarify Procedures 

Continental Airlines asks for 

clarification or instructions regarding 

the filler material between the e-clip, 

part number 411A4902–7, and the wire 

and the clip in the depiction in Boeing 

Service Bulletin 757–21–0109, dated 

December 15, 2006. 

We agree that further clarification is 

needed on this point. Boeing Service 

Bulletin 757–21–0109, Revision 1, dated 

October 30, 2008, provides a filler rod 

part number and corrects the reference 

in note (b) for Figure 3 and Figure 4 of 

that service bulletin. As stated 

previously, we have changed the final 

rule to refer to Revision 1 of the service 

bulletin as the appropriate source of 

service information for this final rule. 

Request To Include Instructions for 

Modified Airplanes 

Continental Airlines requests that we 

revise the NPRM to provide instructions 

for airplanes that are not in the premodification state depicted by Boeing 

Service Bulletin 757–21–0109, dated 

December 15, 2006. 

We find that clarification is necessary. 

Boeing Service Bulletin 757–21–0109, 

Revision 1, dated October 30, 2008, is 

now referenced in the final rule. It 

addresses six new wire configurations 

which take into account the known 

preexisting configurations. We have not 

changed the final rule regarding this 

issue. 

Request To Revise NPRM To Require 

Different Method of Compliance 

Continental Airlines suggests using a 

heat shrinkable sleeve in place of the 

‘‘heat shrinkable’’ sleeve TFE–2X, 

which the commenter states is in fact 

not heat shrinkable. The commenter 

states that in its experience tying the 

lacing tape around the sleeve is 

extremely difficult, and it does not 

believe that the sleeve will stay on 

much more than a year at best. 

We infer that the commenter is 

requesting a different method of 

compliance. We disagree. Boeing 

Service Bulletin 757–21–0109, Revision 

1, dated October 30, 2008, specifies to 

use a sleeve with part number 

65C38488–2. We have not changed the 

final rule regarding this issue. However, 

under the provisions of paragraph (h) of 

this AD, we may approve a request for 

different compliance methods if the 

request includes data that prove that the 

new method provides an acceptable 

level of safety. 

Explanation of Change to Final Rule 

We have clarified paragraph (h) of this 

AD to more accurately identify the 

information for requesting approval of 

an alternative method of compliance 

(AMOC). 

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. 

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 

There are about 920 airplanes of the 

affected design in the worldwide fleet. 

This AD affects about 560 airplanes of 

U.S. registry. The actions take about 2 

work hours per airplane, at an average 

labor rate of $80 per work hour. 

Required parts cost about $81 per 

airplane. Based on these figures, the 

estimated cost of the AD for U.S. 

operators is $134,960, or $241 per 

airplane. 

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.

(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
