SUBJECT CATEGORY:
Airworthiness Directives; McDonnell Douglas Model DC-10-10, DC- 10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, and MD-10-30F Airplanes; and Model MD-11 and MD- 11F Airplanes
DATES: Effective April 7, 2004.
The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of April 7, 2004.
DOCUMENT SUMMARY:
This amendment adopts a new airworthiness directive (AD),
applicable to certain McDonnell Douglas Model DC1010, DC1010F, DC 1015, DC1030, DC1030F (KC10A and KDC10), DC1040, DC1040F,
MD1010F, and MD1030F airplanes; and Model MD11 and MD11F
airplanes. This amendment requires replacement of the left and right
number one passenger door bolted lower sealtoretainer and girt bar
view window assemblies with new, doubleflush riveted assemblies. This
action is necessary to prevent the number one passenger door slide from
inflating before it has cleared the slide cover, which could result in
the slide being unusable during an emergency evacuation and consequent
injury to passengers or airplane crewmembers. This action is intended
to address the identified unsafe condition.
SUMMARY:
McDonnell Douglas,
SUPPLEMENTAL 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 DC1010, DC1010F, DC1015, DC1030, DC1030F (KC10A and KDC10), DC1040, DC1040F, MD1010F, and MD1030F airplanes; and Model MD 11 and MD11F airplanes was published in the Federal Register on September 18, 2003 (68 FR 54682). That action proposed to require replacement of the left and right number one passenger door bolted lower sealtoretainer and girt bar view window assemblies with new, doubleflush riveted assemblies.
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. Conclusion
The FAA has determined that air safety and the public interest require the adoption of the rule as proposed.
Cost Impact
There are approximately 350 Model DC10 airplanes, and approximately 195 Model MD11 and 11F airplanes of the affected design in the worldwide fleet. The FAA estimates that 263 Model DC10 airplanes and 81 Model MD11 and 11F airplanes of U.S. registry would be affected by this AD.
[[Page 9935]]
The following table shows the estimated cost impact for airplanes affected by this AD:
TableCost ImpactEstimated
Labor cost per Parts cost per Maximum fleet
Model Work hours airplane airplane cost
DC10 and MD10 airplane....................... 2 $130 $6,024 $1,618,502
MD11 and 11F airplanes....................... 1 65 6,024 493,209
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 ADDRESSES.
