Federal Register / Vol. 72, No. 219 / Wednesday, November 14, 2007 / Proposed Rules
Revision of the FAA-Approved Maintenance
Inspection Program
(g) Within 12 months after the effective
date of this AD, incorporte a revision into the
FAA-approved maintenance inspection
program that provides no less than the
required damage tolerance assessment/
analysis (DTA) for each structural significant
item (SSI) listed in the SSID. (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.

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

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.

SUMMARY: This document extends the
comment period for the abovereferenced 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.

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
VerDate Aug<31>2005

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.

AGENCY:
SUMMARY: This document extends the
comment period for the abovereferenced NPRM, which proposes the
adoption of a new airworthiness
directive (AD) that applies to certain
Boeing Model 737–600, –700, –700C,
–800, and –900 series airplanes. The
NRPM would require various repetitive
inspections to detect cracks along the
chemically milled steps of the fuselage
skin or missing or loose fasteners in the
area of the preventative modification or
repairs, replacement of the time-limited
repair with the permanent repair if
applicable, and applicable corrective
actions if necessary, which would end
certain repetitive inspections. The
NPRM results from a fatigue test that
revealed numerous cracks in the upper
skin panel at the chemically milled step
above the lap joint. 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.
