This AD requires PO 00000 Frm 00026 Fmt 4700 Sfmt 4700 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.

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. cprice-sewell on PRODPC61 with RULES 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 VerDate Nov<24>2008 14:23 Jun 10, 2009 Jkt 217001 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 PO 00000 Frm 00027 Fmt 4700 Sfmt 4700 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.

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 pre-modification 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.

[[Page 27706]]

    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.
