SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an airworthiness
directive (AD) that is applicable to certain McDonnell Douglas Model
MD-11 and -11F airplanes was published in the Federal Register on
October 5, 2001 (66 FR 50875). That action proposed to require an
inspection of the wiring in the fuel control panel of the wings for
chafing damage and for proper routing of the wiring; and corrective
action(s), if necessary.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. No comments were submitted in response
to the proposal or the FAA's determination of the cost to the public.
Explanation of Change to Applicability
The FAA finds that Model MD-11F airplanes were not specifically
identified by model name in the applicability of the proposed AD.
However, those airplanes were identified by manufacturer's fuselage
numbers in the effectivity listing of Boeing Alert Service Bulletin
MD11-28A058, Revision 01, dated March 29, 2001, which was referenced in
the applicability of the proposed AD. Therefore, we have revised this
AD to specifically reference Model MD-11 and -11F airplanes where
appropriate. In addition, we have revised the applicability of the
existing AD to identify model designations as published in the most
recent type certificate data sheet for the affected models.
Explanation of Change to Inspection Definition
For clarification purposes, the FAA has revised the definition of a
``general visual inspection'' in Note 2 of this final rule.
Conclusion
After careful review of the available data, the FAA has determined
that air safety and the public interest require the adoption of the
rule with the changes previously described. The FAA has determined that
these changes will neither increase the economic burden on any operator
nor increase the scope of the AD.
Cost Impact
There are approximately 78 Model MD-11 and -11F airplanes of the
affected design in the worldwide fleet. The FAA estimates that 30
airplanes of U.S. registry will be affected by this AD, that it will
take approximately 1 work hour per airplane to accomplish the required
inspection, and that the average labor rate is $60 per work hour. Based
on these figures, the cost impact of the AD on U.S. operators is
estimated to be $1,800, or $60 per airplane.
The cost impact figure discussed above is based on assumptions that
no operator has yet accomplished any of the requirements of this AD
action, and that no operator would accomplish those actions in the
future if this AD were not adopted. The cost impact figures discussed
in AD rulemaking actions represent only the time necessary to perform
the specific actions actually required by the AD. These figures
typically do not include incidental costs, such as the time required to
gain access and close up, planning time, or time necessitated by other
administrative actions.
Regulatory Impact
The regulations adopted herein will not have a substantial direct
effect on
[[Page 47654]]
the States, on the relationship between the national Government and the
States, or on the distribution of power and responsibilities among the
various levels of government. Therefore, it is determined that this
final rule does not have federalism implications under Executive Order
13132.
For the reasons discussed above, I certify that this action (1) is
not a ``significant regulatory action'' under Executive Order 12866;
(2) is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and (3) will not have a
significant economic impact, positive or negative, on a substantial
number of small entities under the criteria of the Regulatory
Flexibility Act. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
from the Rules Docket at the location provided under the caption

Adoption of the Amendment
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration amends part 39 of
the Federal Aviation Regulations (14 CFR part 39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding the following new
airworthiness directive:
2002-14-12 McDonnell Douglas: Amendment 39-12812. Docket 2001-NM-
157-AD.
Applicability: Model MD-11 and -11F airplanes, as listed in
Boeing Alert Service Bulletin MD11-28A058, Revision 01, dated March
29, 2001; certificated in any category.
Note 1: This AD applies to each airplane identified in the
preceding applicability provision, regardless of whether it has been
modified, altered, or repaired in the area subject to the
requirements of this AD. For airplanes that have been modified,
altered, or repaired so that the performance of the requirements of
this AD is affected, the owner/operator must request approval for an
alternative method of compliance in accordance with paragraph (b) of
this AD. The request should include an assessment of the effect of
the modification, alteration, or repair on the unsafe condition
addressed by this AD; and, if the unsafe condition has not been
eliminated, the request should include specific proposed actions to
address it.
Compliance: Required as indicated, unless accomplished
previously.
To prevent chafing of the wiring in a cutout area in the wing
fuel control panel due to improperly routed wiring, which could
result in electrical arcing in an abnormal fuel vapor zone and
consequent possible ignition of the fuel vapor, accomplish the
following:
Inspection and Corrective Action, If Necessary
(a) Within 6 months after the effective date of this AD, do a
general visual inspection of the wiring in the fuel control panel of
the wings for chafing damage and for proper routing of the wiring,
per Boeing Alert Service Bulletin MD11-28A058, Revision 01, dated
March 29, 2001.
Note 2: For the purposes of this AD, a general visual inspection
is defined as: ``A visual examination of an interior or exterior
area, installation, or assembly to detect obvious damage, failure,
or irregularity. This level of inspection is made from within
touching distance unless otherwise specified. A mirror may be
necessary to enhance visual access to all exposed surfaces in the
inspection area. This level of inspection is made under normally
available lighting conditions such as daylight, hangar lighting,
flashlight, or droplight and may require removal or opening of
access panels or doors. Stands, ladders, or platforms may be
required to gain proximity to the area being checked.''
(1) Condition 1. If no chafing damage is found and if the wiring
is NOT routed into the cutout area of the fuel control panel, no
further work is required by this AD.
(2) Condition 2. If no chafing damage is found and if the wiring
is routed into the cutout area of the fuel control panel, before
further flight, revise the wire routing out of the cutout area in
the fuel control panel, per the service bulletin.
(3) Condition 3. If any chafing damage is found and if the
wiring is routed into the cutout area of the fuel control panel,
before further flight, replace any damaged wire with a new wire, and
revise the wire routing out of the cutout area in the fuel control
panel, per the service bulletin.
Note 3: Accomplishment of the actions specified in McDonnell
Douglas service Bulletin MD11-28-058, dated January 3, 1995, before
the effective date of this AD, is considered acceptable for
compliance with the requirements of this AD.
Alternative Methods of Compliance
(b) An alternative method of compliance or adjustment of the
compliance time that provides an acceptable level of safety may be
used if approved by the Manager, Los Angeles Aircraft Certification
Office (ACO), FAA. Operators shall submit their requests through an
appropriate FAA Principal Maintenance Inspector, who may add
comments and then send it to the Manager, Los Angeles ACO.
Note 4: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Los Angeles ACO.
Special Flight Permits
(c) Special flight permits may be issued in accordance with
sections 21.197 and 21.199 of the Federal Aviation Regulations (14
CFR 21.197 and 21.199) to operate the airplane to a location where
the requirements of this AD can be accomplished.
Incorporation by Reference
(d) The actions shall be done in accordance with Boeing Alert
Service Bulletin MD11-28A058, Revision 01, dated March 29, 2001.
This incorporation by reference was approved by the Director of the
