Airworthiness Directives; McDonnell Douglas Model MD-11 and -11F 
Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment supersedes an existing airworthiness directive 
(AD), applicable to certain McDonnell Douglas Model MD-11 and -11F 
airplanes, that currently requires, among other actions, a one-time 
inspection to detect discrepancies at certain areas around the entry 
light connector of the sliding ceiling panel above the forward 
passenger doors; repair, if necessary; and installation or modification 
of a flapper door ramp deflector on the forward entry drop ceiling 
structure. That AD also currently requires an inspection of the wire 
assembly support installation above the entry door (L1) sliding panel 
for chafing, and repair, if necessary. This amendment requires the 
existing requirements and requires replacing the wire support bracket 
with new support clip assemblies. The actions specified by this AD are 
intended to prevent chafing of electrical wire assemblies above the 
forward passenger doors and above the entry door (L1) sliding panel of 
the forward drop ceiling on the passenger compartment, which could 
result in electrical arcing, and consequent electrical fire in the 
passenger compartment. This action is intended to address the 
identified unsafe condition.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) by superseding AD 2000-24-11, 
amendment 39-12018 (65 FR 75612, December 4, 2000), which is applicable 
to certain McDonnell Douglas Model MD-11 and -11F airplanes, was 
published in the Federal Register on August 29, 2002 (67 FR 55368). The 
action proposed to continue to require, among other actions, a one-time 
inspection to detect discrepancies at certain areas around the entry 
light connector of the sliding ceiling panel above the forward 
passenger doors; repair, if necessary; and installation or modification 
of a flapper door ramp deflector on the forward entry drop ceiling 
structure. The action also proposed to continue to require an 
inspection of the wire assembly support installation above the entry 
door (L1) sliding panel for chafing, and repair, if necessary. The 
action also proposed to require replacement of the wire support bracket 
with new support clip assemblies.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. Due consideration has been given to 
the comments received.

[[Page 19331]]

Request To Revise the Applicability

    One commenter states that it is exempt from the requirements of 
Boeing Alert Service Bulletin MD11-24A068, Revision 02, dated May 16, 
2001 (which is referenced in the notice of proposed rulemaking (NPRM) 
as an appropriate source of service information for accomplishing 
certain proposed actions), because of the statement in the note in 
paragraph 1., ``Planning Information'' of the service bulletin. The 
note states, ``Airplanes that have been modified from passenger to 
freighter and have had the entry door (L1) sliding panel described in 
this service bulletin removed are not affected.'' The commenter further 
states that its fleet has had all sliding panels removed.
    From this comment, the FAA infers that the commenter is requesting 
that we revise the applicability of the NPRM to exclude those airplanes 
mentioned by the commenter. No change to the final rule is necessary 
because the third column of Table 1--Applicability of this AD already 
excludes affected airplanes ``modified from a passenger to a freighter 
configuration on which the entry door (L1) sliding panel described in 
Boeing Alert Service Bulletin MD11-24A068, Revision 02, dated May 16, 
2001, has been removed.''
    The same commenter notes that in Table 1--Applicability, the first 
service bulletin listed is McDonnell Douglas Alert Service Bulletin 
MD11-24A194, Revision 06, dated January 27, 2000. The commenter 
believes the service bulletin should be MD11-25A194. The commenter 
notes that Service Bulletin MD11-24A194, original issue, dated January 
29, 2002, describes procedures for an inspection of the overhead flight 
compartment, not the L1 entry door.
    From this comment, we infer that the commenter is requesting that 
the correct service bulletin be referenced in the applicability. We 
agree. It was our intent, as noted elsewhere in the NPRM, to specify 
McDonnell Douglas Alert Service Bulletin MD11-25A194, Revision 06, 
dated January 27, 2000, in Table 1--Applicability of this AD. 
Therefore, we have revised that table accordingly.

Request To Reference Latest Service Bulletin

    The same commenter notes that McDonnell Douglas Alert Service 
Bulletin MD11-25A194 is now up to Revision 07, dated January 9, 2002.
    From this comment, we infer that the commenter is requesting that 
the NPRM be revised to reference that revision as an additional source 
of service information for accomplishing the proposed installation and 
modification. We agree. We have reviewed and approved Revision 07 of 
Boeing Alert Service Bulletin MD11-25A194. Revision 07, among other 
editorial changes, deletes fuselage number 0450 from the service 
bulletin effectivity. Therefore, we have revised the final rule to 
reference that revision as an appropriate source of service information 
for determining the applicability of the AD and for accomplishing the 
required installation and modification. In addition, we have revised 
the Cost Impact figures accordingly.

Explanation of Change to Notes

    Since the language in Notes 3 and 5 of the NPRM are regulatory in 
nature, we have redesignated those notes as paragraphs in this final 
rule and have renumbered subsequent paragraphs and notes accordingly.

Explanation of Change to Inspection Definitions

    We have changed all references to a ``detailed visual inspection'' 
in the existing AD (requirements are restated in paragraphs (a) through 
(f) of this final rule) to ``detailed inspection'' in this final rule 
to correspond with the terminology in MSG-3. For clarification 
purposes, we also have revised the definition of a ``detailed 
inspection'' in Note 2 of this final rule and a ``general visual 
inspection'' in Note 3 of this final rule.

Conclusion

    After careful review of the available data, including the comments 
noted above, 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

1. Actions Currently Required by AD 2000-24-11 and Retained in This AD

    There are approximately 110 airplanes of the affected design in the 
worldwide fleet that are affected by the actions currently required by 
AD 2000-24-11 and retained in this AD. Of these 110 airplanes, the FAA 
estimates that 21 airplanes of U.S. registry will be affected by this 
AD.
    The inspection to detect discrepancies around the entry light 
connector of the slide ceiling panel above the forward passenger doors 
takes approximately 2 work hours per airplane to accomplish, at an 
average labor rate of $60 per work hour. Based on these figures, the 
cost impact of this currently required inspection on U.S. operators is 
estimated to be $2,520, or $120 per airplane.
    For Group 1 airplanes as specified in Boeing Alert Service Bulletin 
MD11-25A194, Revision 07 (approximately 16 airplanes of U.S. registry), 
the installation of the flapper door ramp deflector takes approximately 
8 work hours per airplane to accomplish, at an average labor rate of 
$60 per work hour. Required parts cost approximately $455 per airplane. 
Based on these figures, the cost impact of this currently required 
installation on U.S. operators of Group 1 airplanes is estimated to be 
$14,960, or $935 per airplane.
    For Group 2 airplanes as specified in Boeing Alert Service Bulletin 
MD11-25A194, Revision 07 (approximately 8 airplanes of U.S. registry), 
the installation of the flapper door ramp deflector takes approximately 
8 work hours per airplane to accomplish, at an average labor rate of 
$60 per work hour. Required parts cost approximately $890 per airplane. 
Based on these figures, the cost impact of this currently required 
installation on U.S. operators of Group 2 airplanes is estimated to be 
$10,960, or $1,370 per airplane.
    For airplanes listed in McDonnell Douglas Alert Service Bulletin 
MD11-24A068, Revision 01, dated March 8, 1999 (approximately 21 
airplanes of U.S. registry), the inspection of the wire assembly 
support installation takes approximately 1 work hour per airplane to 
accomplish, at an average labor rate of $60 per work hour. Based on 
these figures, the cost impact of this currently required inspection on 
U.S. operators is estimated to be $1,260, or $60 per airplane.
    For airplanes in Groups 1 and 3 as specified in Boeing Alert 
Service Bulletin MD11-25A194, Revision 07 (approximately 18 airplanes 
of U.S. registry), the modification of the ramp deflector assembly 
support bracket takes approximately 2 work hours per airplane to 
accomplish, at an average labor rate of $60 per work hour. Based on 
these figures, the cost impact of this currently required modification 
on U.S. operators is estimated to be $2,160, or $120 per airplane.

2. New Actions Required by This AD

    There are approximately 194 Model MD-11 and -11F airplanes of the 
affected design in the worldwide fleet that are affected by the actions 
required by this AD. Of these 194 airplanes, the FAA estimates that 64 
airplanes of U.S. registry will be affected by this AD.

[[Page 19332]]

    The new actions required by paragraph (g) of this AD will take 
approximately 3 work hours per airplane to accomplish, at an average 
labor rate of $60 per work hour. Required parts will cost approximately 
$294 per airplane. Based on these figures, the cost impact of the new 
requirements of this AD on U.S. operators is estimated to be $30,336, 
or $474 per airplane.

3. Cost Estimate Calculation Information

    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 
from the Rules Docket at the location provided under the caption
