Federal Register / Vol. 72, No. 222 / Monday, November 19, 2007 / Proposed Rules
11 and MD–11F airplanes, certificated in any
category.
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.

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.

(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.

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.

Airworthiness Directives; Boeing

747SR Series Airplanes Powered by

3 or JT9D–7 Series Engines
Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
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.
DATES: We must receive comments on
this proposed AD by January 3, 2008.
ADDRESSES: You may send comments by
any of the following methods:
