Airworthiness Directives; McDonnell Douglas Model DC-10-10, -10F, 
-15, -30, -30F (KC-10A and KDC-10), -40, and -40F Series Airplanes; and 
Model MD-10-10F and MD-10-30F Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This amendment adopts a new airworthiness directive (AD) 
applicable to certain McDonnell Douglas Model DC-10-10, -10F, -15, -30, 
-30F (KC-10A and KDC-10), -40, and -40F series airplanes; and Model MD-
10-10F and MD-10-30F series airplanes. This action requires an 
inspection of the parallel power feeder cables of the number 2 
generator for chafing or structure damage; repositioning of the cables; 
and repair, if necessary. This action is necessary to prevent wire 
chafing of the parallel power feeder cables of the number 2 generator, 
which, if not corrected, could result in electrical arcing and damage 
to adjacent structure, and consequent smoke and/or fire in the aft door 
panel area. This action is intended to address the identified unsafe 
condition.

DATES: Effective May 7, 2002.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of May 7, 2002.

ADDRESSES: The service information referenced in this AD may be 
obtained from Boeing Commercial Aircraft Group, Long Beach Division, 
3855 Lakewood Boulevard, Long Beach, California 90846, Attention: Data 
and Service Management, Dept. C1-L5A (D800-0024). This information may 
be examined at the Federal Aviation Administration (FAA), Transport 
Airplane Directorate, Rules Docket, 1601 Lind Avenue, SW., Renton,

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 McDonnell Douglas Model DC-10-10, 
-10F, -15, -30, -30F (KC-10A and KDC-10), -40, and -40F series 
airplanes; and Model MD-10-10F and MD-10-30F series airplanes was 
published in the Federal Register on January 4, 2002 (67 FR 550). That 
action proposed to require an inspection of the parallel power feeder 
cables of the number 2 generator for chafing or structure damage; 
repositioning of the cables; and repair, if necessary.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. Due consideration has been given to 
the single comment received.
    The commenter supports the proposed rule.

Conclusion

    After careful review of the available data, including the comment 
noted above, the FAA has determined that air safety and the public 
interest require the adoption of the rule as proposed.

Cost Impact

    There are approximately 231 Model DC-10-10, -10F, -15, -30, -30F 
(KC-10A and KDC-10), -40, and -40F series airplanes; and Model MD-10-
10F and MD-10-30F series airplanes of the affected design in the 
worldwide fleet. The FAA estimates that 157 airplanes of U.S. registry 
will be affected by this AD.
    It will take approximately 1 work hour per airplane to accomplish 
the inspection, at an average labor rate of $60 per work hour. Based on 
these figures, the cost impact of the inspection required by this AD on 
U.S. operators is estimated to be $9,420, or $60 per airplane.
    It will take approximately 2 work hours per airplane to accomplish 
the repositioning of cables, at an average labor rate of $60 per work 
hour. Required parts will cost approximately $646 per airplane. Based 
on these figures, the cost impact of the repositioning of cables 
required by this AD on U.S. operators is estimated to be $120,262, or 
$766 per airplane.
    The cost impact figures discussed above are 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 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

    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 wire chafing of the parallel power feeder cables of 
the number 2 generator, which, if not corrected, could result in 
electrical arcing and damage to adjacent structure, and consequent 
smoke and/or fire in the aft door panel area, accomplish the 
following:

Inspection and Follow-On Actions

    (a) Within 6 months after the effective date of this AD, do a 
one-time general visual inspection of the parallel power feeder 
cables of the number 2 generator for chafing or structure damage, 
per Boeing Alert Service Bulletin DC10-24A170, Revision 01, dated 
September 25, 2001.
    (1) Condition 1. If no chafing or structure damage is found: At 
the next scheduled maintenance visit, but no later than 6 months 
after the effective date of this AD, reposition the cables per the 
alert service bulletin.
    (2) Condition 2. If any chafing or structure damage is found: 
Prior to further flight, repair the cable and damaged adjacent 
structure, as applicable, and reposition the cables, per the alert 
service bulletin.

    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 under normally 
available lighting conditions such as daylight, hangar lighting, 
flashlight, or drop-light, 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.''

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 3: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the Los Angeles ACO.
