Note 1: This AD requires revisions to certain operator maintenance documents to include new inspections and maintenance actions. Compliance with these limitations is required by 14 CFR 43.16 and 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these limitations, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 43.16 and 91.403(c), the operator must request approval for revision to the airworthiness limitations (AWLs) in the Boeing Trijet Special Compliance Item Report, MDC–02K1003, according to paragraph (g), (h), or (k) of this AD, as applicable. Unsafe Condition (d) This AD results from a design review of the fuel tank systems. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. Compliance (e) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Initial Inspection and Repair If Necessary (i) For Model MD–11 and MD–11F airplanes: Within 60 months after the effective date of this AD, do a detailed inspection of the metallic overbraiding and red-wrap tape installed on the tail tank fuel quantity indication system (FQIS) wiring to verify if the metallic overbraiding or redwrap tape is damaged or shows signs of deterioration, in accordance with ALI 20–2 of Appendix C of Report MDC–02K1003. If any discrepancy is found during the inspection, repair the discrepancy before further flight in accordance with ALI 20–2 of Appendix C of Report MDC–02K1003. Accomplishing the actions required by this paragraph in accordance with a later revision of Report MDC–02K1003 is an acceptable method of compliance if the revision is approved by the Manager, Los Angeles ACO. Note 2: For the purposes of this AD, a detailed inspection is: ‘‘An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.’’ No Reporting Requirement (j) Although Report MDC–02K1003 specifies to submit certain information to the manufacturer, this AD does not require that action. Revise the FAA-Approved Maintenance Program (g) For Model DC–10–10 and DC–10–10F airplanes, Model DC–10–15 airplanes, Model DC–10–30 and DC–10–30F (KC–10A and KDC–10) airplanes, and Model DC–10–40 and DC–10–40F airplanes: Before December 16, 2008, revise the FAA-approved maintenance program to incorporate the information specified in Appendixes B, C, and D of Report MDC–02K1003. Accomplishing the revision in accordance with a later revision of Report MDC–02K1003 is an acceptable method of compliance if the revision is approved by the Manager, Los Angeles Aircraft Certification Office (ACO), FAA. ebenthall on PRODPC61 with PROPOSALS Service Information Reference (f) The term ‘‘Report MDC–02K1003’’ as used in this AD, means the Boeing Trijet Special Compliance Item Report, MDC– 02K1003, Revision C, dated July 24, 2007. Alternative Methods of Compliance (AMOCs) Revise the AWLs Section (h) For Model MD–10–10F and MD–10– 30F airplanes, and Model MD–11 and MD– 11F airplanes: Before December 16, 2008, revise the AWLs section of the Instructions for Continued Airworthiness to incorporate the information specified in Appendixes B, C, and D of Report MDC–02K1003, except that the initial inspection required by paragraph (i) of this AD must be done at the applicable compliance time specified in that paragraph. Accomplishing the revision in accordance with a later revision of Report MDC–02K1003 is an acceptable method of compliance if the revision is approved by the Manager, Los Angeles ACO. VerDate Aug<31>2005 15:42 Nov 16, 2007 Jkt 214001 (k)(1) The Manager, Los Angeles ACO, FAA, has the authority to approve AMOCs for this AD, if requested 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.

DEPARTMENT OF TRANSPORTATION We proposed to amend 14 CFR part 39 with a notice of proposed rulemaking (NPRM) for an AD for all ATR Model ATR42 and ATR72 airplanes. The NPRM was published in the Federal Register on September 28, 2007 (72 FR 55113). The NPRM proposed to require revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems. The NPRM action invites comments on the overall regulatory, economic, environmental, and energy aspects of the proposed AD. RIN 2120–AA64 FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: ebenthall on PRODPC61 with PROPOSALS Actions Since NPRM Was Issued 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 reopen the comment period for 30 days to receive additional comments. No part of the regulatory information has been changed; therefore, the NPRM is not republished in the Federal Register. Comments Due Date We must receive comments on this AD action by December 19, 2007.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747–100, –100B, –100B SUD, –200B, –200C, –200F, –300, 747SP, and 747SR series airplanes powered by General Electric (GE) CF6– 45/50 and Pratt & Whitney (P&W) JT9D– 70, JT9D–3 or JT9D–7 series engines. This proposed AD would require repetitive inspections to find cracks and broken fasteners of the rear engine mount bulkhead of the inboard and outboard nacelle struts, and repair if necessary. For certain airplanes, this proposed AD mandates a terminating modification for certain inspections of the inboard and outboard nacelle struts. This proposed AD results from reports of web and frame cracks and sheared attachment fasteners on the inboard and outboard nacelle struts. We are proposing this AD to detect and correct cracks and broken fasteners of the inboard and outboard nacelle struts, which could result in possible loss of the rear engine mount bulkhead load path and consequent separation of the engine from the airplane.

SUPPLEMENTARY INFORMATION: We proposed to amend 14 CFR part 39 with a 
notice of proposed rulemaking (NPRM) for an AD for all ATR Model ATR42 
and ATR72 airplanes. The NPRM was published in the Federal Register on 
September 28, 2007 (72 FR 55113). The NPRM proposed to require revising 
the Airworthiness Limitations Section of the Instructions for Continued 
Airworthiness to incorporate new limitations for fuel tank systems. The 
NPRM action invites comments on the overall regulatory, economic, 
environmental, and energy aspects of the proposed AD.

Actions Since NPRM Was Issued

    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 reopen the comment period for 30 days to receive additional 
comments.
    No part of the regulatory information has been changed; therefore, 
the NPRM is not republished in the Federal Register.

Comments Due Date

    We must receive comments on this AD action by December 19, 2007.
