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 ST01783AT-D, that requires modifying the in-flight entertainment (IFE) system and revising the airplane flight manual. The actions specified by this AD are intended to ensure that the flight crew is able to remove electrical power from the IFE system when necessary and is advised of appropriate procedures for such action. 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 May 21, 2003.

The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of May 21, 2003.

ADDRESSES:

The service information referenced in this AD may be obtained from TIMCO Engineered Systems, Inc., 623 Radar Road, Greensboro, North Carolina 27410. This information may be examined at the FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington; or at the FAA, Atlanta Aircraft Certification Office, One Crown Center, 1895 Phoenix Boulevard, suite 450, Atlanta, Georgia; 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 ST01783AT-D was published in the Federal Register on January 3, 2003 (68 FR 308). That action proposed to require modifying the in-flight entertainment (IFE) system and revising the airplane flight manual.

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 37 airplanes of the affected design in the worldwide fleet. The FAA estimates that 37 airplanes of U.S. registry will be affected by this AD.

It will take approximately 66 work hours per airplane to accomplish the modification, at an average labor rate of $60 per work hour. Based on these figures, the cost impact of the modification on U.S. operators is estimated to be $146,520, or $3,960 per airplane.

It will take approximately 1 work hour per airplane to accomplish the AFM revision, at an average labor rate of $60 per work hour. Based on these figures, the cost impact of the AFM revision on U.S. operators is estimated to be $2,220, or $60 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 Start Printed Page 18536responsibilities 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.

End Amendment Part

2003-07-15 Boeing: Amendment 39-13111. Docket 2002-NM-54-AD.

Applicability: Model 767-300 series airplanes modified by Supplemental Type Certificate (STC) ST01783AT-D, certificated in any category.

Note 1:

This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been otherwise 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 (c) 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 ensure that the flight crew is able to remove electrical power from the in-flight entertainment (IFE) system when necessary and is advised of appropriate procedures for such action, accomplish the following:

Modification and Airplane Flight Manual Revision

(a) Within 18 months after the effective date of this AD, accomplish paragraphs (a)(1) and (a)(2) of this AD.

(1) Modify the IFE system installed on the airplane by installing two new relays and a new circuit breaker, according to TIMCO Service Bulletin TSB-767-23-009, Revision IR, dated August 22, 2001.

(2) Revise the procedures under “Electrical Smoke or Fire” in the “Emergency Procedures” section of the airplane flight manual (AFM) to include TIMCO AFM Supplement TIM-AFM-01035, dated March 13, 2002. When the information in that AFM supplement has been incorporated into the FAA-approved general revisions of the AFM, the general revisions may be incorporated into the AFM, and the AFM supplement may be removed from the AFM.

Part Installation

(b) As of the effective date of this AD, no person may install an IFE system according to STC ST01783AT-D on any airplane, unless the IFE system is modified and the AFM is revised according to this AD.

Alternative Methods of Compliance

(c) 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, Atlanta 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, Atlanta ACO.

Note 2:

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

Special Flight Permits

(d) Special flight permits may be issued in accordance with §§ 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

(e) The modification shall be done in accordance with TIMCO Service Bulletin TSB-767-23-009, dated August 22, 2001; the AFM revision shall be done in accordance with TIMCO Airplane Flight Manual Supplement TIM-AFM-01035, dated March 13, 2002. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies may be obtained from TIMCO Engineered Systems, Inc., 623 Radar Road, Greensboro, North Carolina 27410. Copies may be inspected at the FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington; or at the FAA, Atlanta Aircraft Certification Office, One Crown Center, 1895 Phoenix Boulevard, suite 450, Atlanta, Georgia; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC.
