[Docket No. FAA–2007–28355; Directorate Identifier 2007–NM–062–AD; Amendment 39–15495; AD 2008–09–14] SUPPLEMENTARY INFORMATION: RIN 2120–AA64 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 737–600, –700, –700C, –800 and –900 series airplanes. That NPRM was published in the Federal Register on June 6, 2007 (72 FR 31202). That NPRM proposed to require inspecting ground blocks GD261 and GD264 for corrosion, measuring the electrical bond resistance between the ground blocks and the airplane structure, separating the ground wires for the fuel boost pump circuit between ground blocks GD261 and GD264, and doing corrective actions if necessary. Airworthiness Directives; Boeing Model 737–600, –700, –700C, –800 and –900 Series Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: SUMMARY: We are adopting a new airworthiness directive (AD) for certain Boeing Model 737–600, –700, –700C, –800 and –900 series airplanes. This AD requires inspecting ground blocks GD261 and GD264 for corrosion, measuring the electrical bond resistance between the ground blocks and the airplane structure, separating the ground wires for the fuel boost pump circuit between ground blocks GD261 and GD264, and doing corrective actions if necessary. This AD results from a report of random flashes of the six fuel pump low pressure lights and intermittent operation of the fuel boost pumps. We are issuing this AD to prevent the simultaneous malfunction of all six fuel boost pumps, which could cause the engines to operate on suction feed and potentially flame out. DATES: This AD is effective June 6, 2008. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of June 6, 2008.

FOR FURTHER INFORMATION CONTACT: Binh Tran, Aerospace Engineer, Systems PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 Discussion Comments We gave the public the opportunity to participate in developing this AD. We have considered the comments received. Support for the NPRM AirTran Airways supports the NPRM. Request to Incorporate Revised Service Bulletin The NPRM referred to Boeing Special Attention Service Bulletin 737–28– 1257, dated February 26, 2007, as the appropriate source of service information for the proposed requirements. Boeing requests that we revise the NPRM to refer to Revision 1 of the service bulletin, which Boeing issued after we issued the NPRM. We have reviewed the revised service bulletin. In Revision 1, dated November 28, 2007, Boeing removed certain annunciator checks, updated temperature control operational test instructions, and removed certain wire separation requirements. Revision 1 provides no substantive changes or additional work. We agree to revise the final rule to require Revision 1, and to provide credit for the original version. 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.

This AD requires repetitive inspections for any cracking of or damage to the left side and right side flight deck No. 2, No. 4, and No. 5 windows and corrective actions if necessary. This AD results from reports of in-flight departure and separation of the flight deck windows. We are issuing this AD to detect and correct cracking in the vinyl interlayer or damage to the structural inner glass panes of the flight deck No. 2, No. 4, and No. 5 windows, which could result in loss of a window and rapid loss of cabin pressure. Loss of cabin pressure could cause crew communication difficulties or crew incapacitation. DATES: This AD is effective June 6, 2008.

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 all Boeing Model 737–100, –200, –200C, –300, –400, and –500 series airplanes. That NPRM was published in the Federal Register on October 17, 2007 (72 FR 58766). That NPRM proposed to require repetitive inspections for any cracking of or damage to the left side and right side flight deck No. 2, No. 4, and No. 5 windows and corrective actions if necessary. Changes Made to This AD We have deleted paragraph (h)(4) of the NPRM and added a new paragraph (h) to this AD specifying that installation of metallic window blanks at cockpit eyebrow windows No. 4 and No. 5 in accordance with Supplemental Type Certificate (STC) ST01630SE terminates the initial and repetitive inspections for the flight deck No. 4 and No. 5 windows required by paragraph (f) of this AD. Incorporation of STC ST01630SE is considered a terminating action, not an alternative method of compliance (AMOC), since an AMOC can only be issued after an AD has been issued. We have also reidentified the AMOC paragraph of the NPRM as paragraph (i) in this AD. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received from the three commenters. Support for the NPRM Boeing and Continental Airlines support the NPRM. Request to Expand Applicability North Star Aerospace states that the affected window panels are also installed on Boeing Model 707 and 727 airplanes and Model 737–600, –700, –800, and –900 series airplanes, and that it has witnessed failure of the windows on these airplanes. North Star PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 24151 Aerospace believes the inspections should be extended to include all airplanes equipped with window panels having part numbers (P/Ns) 5–89355– ( ), 5–89357–( ), and 5–89358–( ). We infer the commenter requests that we revise the applicability to add Model 707 and 727 airplanes and Model 737– 600, –700, –800, and –900 series airplanes. Since the affected windows are interchangeable, we agree that the windows might be installed on all Model 707, 727, and 737 airplanes. However, we do not agree to expand the applicability of this AD, since we have issued separate rulemaking actions to address the unsafe condition on Model 707 and 727 airplanes and Model 737– 600, –700, –800, and –900 series airplanes. Please refer to Docket Nos. FAA–2007–0264, FAA–2007–0265, and FAA–2007–0263, respectively, at https://www.regulations.gov. No change to this AD is necessary in this regard. Request To Revise the Compliance Time Continental Airlines requests that we revise the compliance time for the initial inspection of the flight deck No. 2 window to within 36 months or 7,500 flight hours, whichever occurs first, after the window installation. Continental Airlines states that the NPRM, which proposes to require the initial inspection within 24 months after the effective date of this AD regardless of the age or flight time of the window, unnecessarily penalizes operators who proactively inspect and replace the No. 2 window before the AD is issued. Continental Airlines also states that, according to the wording in the NPRM, a window replaced one day before the effective date of the AD would need to be re-inspected within 24 months, but a window inspected and replaced one day after the effective date of the AD would not need to be re-inspected until 36 months or 7,500 window flight hours, whichever is first. We do not agree to revise the compliance time for the initial inspection of the flight deck No. 2 window. According to paragraph (e) of this AD, an operator is responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. If the initial inspection of the No. 2 window was done before the effective date of this AD in accordance with Boeing Alert Service Bulletin 737–56A1023, dated May 24, 2007, then the initial inspection does not need to be accomplished again; only the repetitive inspections would need to be accomplished in accordance with the service bulletin at the applicable E:\FR\FM\02MYR1.SGM 02MYR1

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Boeing Model 737-600, -700, -700C, -800 and -900 series airplanes. This 
AD requires inspecting ground blocks GD261 and GD264 for corrosion, 
measuring the electrical bond resistance between the ground blocks and 
the airplane structure, separating the ground wires for the fuel boost 
pump circuit between ground blocks GD261 and GD264, and doing 
corrective actions if necessary. This AD results from a report of 
random flashes of the six fuel pump low pressure lights and 
intermittent operation of the fuel boost pumps. We are issuing this AD 
to prevent the simultaneous malfunction of all six fuel boost pumps, 
which could cause the engines to operate on suction feed and 
potentially flame out.

DATES: This AD is effective June 6, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of June 6,

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 737-600, -700, -700C, -800 and -900 series 
airplanes. That NPRM was published in the Federal Register on June 6, 
2007 (72 FR 31202). That NPRM proposed to require inspecting ground 
blocks GD261 and GD264 for corrosion, measuring the electrical bond 
resistance between the ground blocks and the airplane structure, 
separating the ground wires for the fuel boost pump circuit between 
ground blocks GD261 and GD264, and doing corrective actions if 
necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comments received.

Support for the NPRM

    AirTran Airways supports the NPRM.

Request to Incorporate Revised Service Bulletin

    The NPRM referred to Boeing Special Attention Service Bulletin 737-
28-1257, dated February 26, 2007, as the appropriate source of service 
information for the proposed requirements. Boeing requests that we 
revise the NPRM to refer to Revision 1 of the service bulletin, which 
Boeing issued after we issued the NPRM.
    We have reviewed the revised service bulletin. In Revision 1, dated 
November 28, 2007, Boeing removed certain annunciator checks, updated 
temperature control operational test instructions, and removed certain 
wire separation requirements. Revision 1 provides no substantive 
changes or additional work. We agree to revise the final rule to 
require Revision 1, and to provide credit for the original version.

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.

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.

Unsafe Condition

    (d) This AD results from a report of random flashes of the six

corrosion, measure the electrical bond resistance, and separate the

GD261 and GD264. Do these actions in accordance with the 
Accomplishment Instructions of Boeing Special Attention Service 
Bulletin 737-28-1257, Revision 1, dated November 28, 2007. Do
