14 CFR Part 39
[Docket No. FAA-2007-29335; Directorate Identifier 2007-NM-045-AD]
RIN 2120-AA64
Airworthiness Directives; McDonnell Douglas Model DC-9-81 (MD-
81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and MD-88
Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM); extension of comment
period.
-----------------------------------------------------------------------
SUMMARY: This document extends the comment period for the above-
referenced NPRM, which proposes the adoption of a new airworthiness
directive (AD) that applies to all McDonnell Douglas Model DC-9-81 (MD-
81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and MD-88
airplanes. The NPRM would require repetitive inspections for cracking
of the overwing frames from stations 845 to 905 (MD-87 stations 731 to
791), left and right sides, and corrective actions if necessary. The
NPRM results from reports of cracked overwing frames. This extension of
the comment period is necessary to ensure that all interested persons
have ample opportunity to submit any written relevant data, views, or
arguments regarding the NPRM.
DATES: We must receive comments on this NPRM by December 3, 2007.

SUPPLEMENTARY INFORMATION: We proposed to amend 14 CFR part 39 with a
notice of proposed rulemaking (NPRM) for an AD (the ``original NPRM'')
for all McDonnell Douglas Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-
83 (MD-83), DC-9-87 (MD-87), and MD-88 airplanes. The original NPRM was
published in the Federal Register on September 28, 2007 (72 FR 55111).
The original NPRM proposed to require repetitive inspections for
cracking of the overwing frames from stations 845 to 905 (MD-87
stations 731 to 791), left and right sides, and corrective actions if
necessary. The original NPRM also invites comments on its overall
regulatory, economic, environmental, and energy aspects.
Events Leading to Extension of Comment Period
Since we issued the NPRM, the DOT's Docket Management System (DMS)
was replaced by the Federal Docket Management System (FDMS). FDMS is a
government-wide, electronic docket management system, which contains
the public dockets and is the method used for submitting comments on
the overall regulatory, economic, environmental, and energy aspects of
proposed rulemaking actions. However, due to the service disruption
caused by the transition from DOT's DMS to the FDMS, the docket
material was not posted on the FDMS until November 1, 2007. Therefore,
we have determined that the public was not provided adequate
opportunity to submit comments on the NPRM. As a result, we have
decided to extend the comment period for this NPRM until December 3,
2007, to receive additional comments.
FAA's Determination
We have considered this issue and find it appropriate to extend the
comment period to give all interested persons additional time to
examine the proposed requirements of the original NPRM and submit
comments. After evaluating the circumstances stated previously, we have
determined that extending the comment period until December 3, 2007,
will not compromise the safety of these airplanes.
Extension of Comment Period
The comment period for Docket No. FAA-2007-29335; Directorate
Identifier 2007-NM-045-AD; has been revised. The comment period now
closes December 3, 2007.
No other part of the regulatory information has been changed;
therefore, the original NPRM is not republished in the Federal
Register.
Issued in Renton, Washington, on November 7, 2007.
