Start Preamble

AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Final rule.

SUMMARY:

This amendment adopts a new airworthiness directive (AD), applicable to all Boeing Model 767-300 series airplanes modified by supplemental type certificate ST00157SE, that requires modification of the electrical circuits that supply power to the in-flight entertainment (IFE) system. This action is necessary to prevent the inability of the flight crew to remove power from the IFE system when necessary. Inability to remove power from the IFE system during a non-normal or emergency situation could result in inability to control smoke or fumes in the airplane flight deck or cabin. This action is intended to address the identified unsafe condition.

DATES:

Effective September 21, 2001.

The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of September 21, 2001.

ADDRESSES:

The service information referenced in this AD may be obtained from JAMCO America, Inc., 1018 80th Street SW., Everett, Washington 98023. This information may be examined at the Federal Aviation Administration (FAA), Transport Airplane Directorate, Rules Docket, 1601 Lind Avenue, SW., Renton, Washington; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC.

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 all Boeing Model 767-300 series airplanes modified by supplemental type certificate (STC) ST00157SE was published in the Federal Register on March 29, 2001 (66 FR 17121). That action proposed to require modification of the electrical circuits that supply power to the in-flight entertainment (IFE) system.

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.

One commenter states that it does not operate any of the airplanes affected by the proposed AD, and thus has no comment.

Use Modification Developed by Airplane Manufacturer

One commenter requests that the FAA revise the proposed AD to require modification per procedures developed by the airplane manufacturer (Boeing) rather than by the STC holder (JAMCO America). The commenter states that a modification developed by the airplane manufacturer is appropriate because installation of an IFE system per the subject STC does not change the power distribution from the production configuration. The commenter states that it acknowledges the intent of the proposed AD, but it would prefer a solution developed by Boeing to ensure commonality among all Boeing Model 767-300 series airplanes. The commenter notes that such commonality is important for operating and maintenance procedures. The commenter also adds that, if the FAA adopts its recommendation, the compliance time for the proposed AD should be extended to allow time for Boeing to release a service bulletin and for the affected operators to do the modification.

We do not concur with the commenter's request. The IFE system—including the electrical components and wiring that provides electrical power to the system—was installed by the STC holder and is not common to all Boeing Model 767-300 series airplanes. The fact that installation of the subject IFE system was approved by STC indicates that it represents a major change from the design previously approved under the type certificate for the Model 767-300 series airplanes. As such, the STC Start Printed Page 43071holder, not the airplane manufacturer, is responsible for the development of corrective actions for potential unsafe conditions related to any part of the airplane modified per the STC.

Further, contrary to what the commenter states, the installation of the IFE system by the subject STC does include wiring changes, as well as the redesignation and reassignment of several circuit breakers in the P37 Right Miscellaneous Equipment Panel on the airplane. The development of an appropriate modification necessitates knowledge of the wiring and circuit breaker changes involved with installation of the system. We cannot assume that the airplane manufacturer has the necessary engineering data, since these data are proprietary to the holder of the subject STC.

Also, since the STC holder has already developed appropriate service information (as described in the proposed AD), there is no reason to extend the compliance time as requested by the commenter. No change to the final rule is necessary in this regard.

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 as proposed.

Cost Impact

There are approximately 49 Model 767-300 series airplanes modified by STC ST00157SE in the worldwide fleet. The FAA estimates that 49 airplanes of U.S. registry will be affected by this AD, that it will take approximately 3 work hours per airplane to accomplish the required actions, and that the average labor rate is $60 per work hour. Required parts will cost approximately $80 per airplane. Based on these figures, the cost impact of this AD on U.S. operators is estimated to be $12,740, or $260 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 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.
