(The required DTA value for each SSI is listed in the SSID.) The revision to the maintenance inspection program must include and must be implemented in accordance with the procedures in Section 5.0, ‘‘Damage Tolerance Analysis Methodology,’’ and Section 7.0, ‘‘Discrepancy Reporting,’’ of the SSID. Under the provisions of the Paperwork Reduction Act of 1980 (44 U.S.C. 3501, et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements contained in this AD and has assigned OMB Control Number 2120–0056. pwalker on PROD1PC71 with PROPOSALS Initial and Repetitive Inspections (h) At the later of the times specified in paragraphs (h)(1) and (h)(2) of this AD, except as provided by paragraphs (i) through (m) of this AD: Do the applicable initial inspections to detect cracks of all SSIs, in accordance with the SSID. Repeat the applicable inspections thereafter at intervals not to exceed the ‘‘Recurring’’ intervals specified in Section 6.0.0 of the SSID, except as provided by paragraphs (k) through (m) of this AD. (1) Before the applicable ‘‘Initial’’ threshold specified in Section 6.0.0, ‘‘Structural Inspection Requirements’’ of the SSID. (2) Within 36 months after the effective date of this AD, or within one ‘‘Recurring’’ interval measured from 12 months after the effective date of the AD, whichever comes first. Exceptions to the SSID (i) Where Section 6.0.0 of the SSID specifies the ‘‘Initial’’ threshold in years (since new), this AD requires compliance within the specified year since the date of issuance of the original standard airworthiness certificate or the date of issuance of the original export certificate of airworthiness. (j) Where Section 6.0 of the SSID specifies the ‘‘Initial’’ threshold as ‘‘Special Condition,’’ this AD requires compliance within 24 months after the effective date of this AD. (k) Where Section 6.0 of the SSID specifies the ‘‘Initial’’ threshold and ‘‘Recurring’’ interval as ‘‘FS 1041 Fitting Replacement,’’ this AD requires compliance within 24 months after the effective date of this AD and thereafter at intervals not to exceed 12 months. (l) Where Section 6.0 of the SSID specifies the ‘‘Initial’’ threshold and ‘‘Recurring’’ interval as ‘‘Engine Change,’’ this AD requires compliance within 24 months after the effective date of this AD and thereafter at intervals not to exceed 36 months. (m) Where Section 6.0 of the SSID specifies the ‘‘Initial’’ threshold and ‘‘Recurring’’ interval as ‘‘Aft Lord Mount Change,’’ this VerDate Aug<31>2005 16:00 Nov 13, 2007 Jkt 214001 AD requires compliance within 24 months after the effective date of this AD and thereafter at intervals not to exceed 24 months. Repair (n) If any cracked structure is found during any inspection required by paragraph (h) of this AD, before further flight, repair the cracked structure using a method approved by the Manager, Atlanta Aircraft Certification Office (ACO), FAA. For a repair method to be approved by the Manager, Atlanta ACO, as required by this paragraph, the Manager’s approval letter must specifically refer to this AD. Inspection Program for Transferred Airplanes (o) Before any airplane that is subject to this AD and that has exceeded the applicable compliance times specified in paragraph (h) of this AD can be added to an air carrier’s operations specifications, a program for the accomplishment of the inspections required by this AD must be established in accordance with paragraph (o)(1) or (o)(2) of this AD, as applicable. (1) For airplanes that have been inspected in accordance with this AD: The inspection of each SSI must be done by the new operator in accordance with the previous operator’s schedule and inspection method, or the new operator’s schedule and inspection method, at whichever time would result in the earlier accomplishment for that SSI inspection. The compliance time for accomplishment of this inspection must be measured from the last inspection accomplished by the previous operator. After each inspection has been done once, each subsequent inspection must be performed in accordance with the new operator’s schedule and inspection method. (2) For airplanes that have not been inspected in accordance with this AD: The inspection of each SSI required by this AD must be done either before adding the airplane to the air carrier’s operations specification, or in accordance with a schedule and an inspection method approved by the Manager, Atlanta Aircraft Certification Office (ACO), FAA. After each inspection has been done once, each subsequent inspection must be done in accordance with the new operator’s schedule. Alternative Methods of Compliance (AMOCs) (p)(1) The Manager, Atlanta ACO, has the authority to approve AMOCs for this AD, if required in accordance with the procedures found in 14 CFR 39.19. (2) To request a different method of compliance or a different compliance time for this AD, follow the procedures in 14 CFR 39.19. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO.

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. pwalker on PROD1PC71 with PROPOSALS 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.

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.
