ACTION: Final rule. AGENCY: SUMMARY: We are adopting a new airworthiness directive (AD) for all Boeing Model 727 airplanes. 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, as necessary, 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. This AD is effective July 3, 2008. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of July 3, 2008. ADDRESSES: For service information identified in this AD, contact Boeing Commercial Airplanes, P.O. Box 3707, Seattle, Washington 98124–2207.

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 727 series airplanes. That NPRM was published in the Federal Register on December 3, 2007 (72 FR 67873). 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, as necessary, 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) ST01704SE 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 ST01704SE 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 two commenters. Examining the AD Docket Support for the NPRM Boeing supports the NPRM. You may examine the AD docket on the Internet at https:// www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this AD, the regulatory Request To Extend Compliance Times FedEx requests that we extend the compliance time to 36 months or 3,600 flight hours, whichever occurs later, for the initial inspections of the flight deck No. 2, No. 4, and No. 5 windows and the repetitive intervals for the No. 4 and No. PO 00000 Frm 00037 Fmt 4700 Sfmt 4700 E:\FR\FM\29MYR1.SGM 29MYR1 30764 Federal Register / Vol. 73, No. 104 / Thursday, May 29, 2008 / Rules and Regulations 5 windows. FedEx states this extension will allow it to do the initial inspections at a scheduled maintenance check. FedEx also states that extending the repetitive interval will allow the repetitive inspections of the No. 2, No. 4, and No. 5 to be done concurrently. We do not agree with the request to extend certain compliance times. In developing an appropriate compliance time for this action, we considered the urgency associated with the subject unsafe condition and the practical aspect of accomplishing the required inspections within a period of time that corresponds to the normal scheduled maintenance for most affected operators. However, according to the provisions of paragraph (i) of this AD, we may approve requests to adjust the compliance time if the request includes data that show that the new compliance time would provide an acceptable level of safety. 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. 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment pwalker on PROD1PC71 with RULES Costs of Compliance There are about 790 airplanes of the affected design in the worldwide fleet. This AD affects about 431 airplanes of U.S. registry. The required actions take about 2 work hours per airplane, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the AD for U.S. operators is $68,960, or $160 per airplane, per inspection cycle. I 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 § 39.13 VerDate Aug<31>2005 17:07 May 28, 2008 Jkt 214001 Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

Request To Delay Issuance of Final Rule FedEx and Boeing request that we delay issuance of the final rule until Boeing releases a revision to Boeing Alert Service Bulletin DC10–27A237, dated January 9, 2007 (referred to as an appropriate source of service information for accomplishing the actions specified in the NPRM), and to Drawing SR11530052, and necessary parts are available. FedEx notes that Boeing released Information Notice DC10–27A237 IN 01, dated August 8, 2007, which indicates that the procedures specified in Boeing Alert Service Bulletin DC10–27A237 for Model DC–10–10F and MD–10–10F airplanes cannot be done. Boeing states that the engineering provided in Drawing SR11530052, which is referred to in Boeing Alert Service Bulletin DC10–27A237, does not reflect the existing structural configuration used on Model DC–10–10F and MD–10–10F airplanes. Since issuance of the NPRM, we have reviewed Boeing Alert Service Bulletin DC10–27A237, Revision 1, dated December 20, 2007. Revision 1 revises Drawing SR11530052 to account for different panel configurations on Model DC–10–10F and MD–10–10F airplanes and adds airplane groups for those affected airplanes. Revision 1 also removes Model DC–10–10 airplanes, which are not subject to the identified unsafe condition of this AD.

Airworthiness Directives; Boeing Model 727 Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Boeing Model 727 airplanes. 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, as necessary, 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.

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 727 series airplanes. That NPRM was published in the 
Federal Register on December 3, 2007 (72 FR 67873). 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, 
as necessary, 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) ST01704SE 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 
ST01704SE 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 two commenters.

Support for the NPRM

    Boeing supports the NPRM.

Request To Extend Compliance Times

    FedEx requests that we extend the compliance time to 36 months or 
3,600 flight hours, whichever occurs later, for the initial inspections 
of the flight deck No. 2, No. 4, and No. 5 windows and the repetitive 
intervals for the No. 4 and No.

[[Page 30764]]

5 windows. FedEx states this extension will allow it to do the initial 
inspections at a scheduled maintenance check. FedEx also states that 
extending the repetitive interval will allow the repetitive inspections 
of the No. 2, No. 4, and No. 5 to be done concurrently.
    We do not agree with the request to extend certain compliance 
times. In developing an appropriate compliance time for this action, we 
considered the urgency associated with the subject unsafe condition and 
the practical aspect of accomplishing the required inspections within a 
period of time that corresponds to the normal scheduled maintenance for 
most affected operators. However, according to the provisions of 
paragraph (i) of this AD, we may approve requests to adjust the 
compliance time if the request includes data that show that the new 
compliance time would provide an acceptable level of safety.

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 790 airplanes of the affected design in the 
worldwide fleet. This AD affects about 431 airplanes of U.S. registry. 
The required actions take about 2 work hours per airplane, at an 
average labor rate of $80 per work hour. Based on these figures, the 
estimated cost of the AD for U.S. operators is $68,960, or $160 per 
airplane, per inspection cycle.

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.

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.

AD performed within the compliance times specified, unless the 
actions have already been done.

Repetitive Inspections and Replacement

internal and external detailed inspections for any cracking of or 
damage to the left side and right side flight deck No. 2, No. 4, and 
No. 5 windows, as applicable, and do the applicable corrective 
actions before further flight, by accomplishing all of the 
applicable actions specified in the Accomplishment Instructions of 
Boeing Alert Service Bulletin 727-56A0019, dated June 6, 2007. 
Repeat the inspections thereafter at the applicable interval 
specified in paragraph 1.E. of Boeing Alert Service Bulletin 727-
56A0019, dated June 6, 2007.

Exception to Compliance Times

    (g) Where Tables 1, 2, and 3 of paragraph 1.E. of Boeing Alert 
Service Bulletin 727-56A0019, dated June 6, 2007, specify counting 
the compliance time from ``* * * the date on this service 
bulletin,'' this AD requires counting the compliance time from the 
effective date of this AD.

Optional Terminating Action

    (h) Installation of metallic window blanks at cockpit eyebrow 
windows No. 4 and No. 5 in accordance with Supplemental Type 
Certificate ST01704SE terminates the initial and repetitive 
inspections for the flight deck No. 4 and No. 5 windows required by
