04-5432. Airworthiness Directives; Boeing Model 737-200 Series Airplanes Modified by Supplemental Type Certificate ST00516AT

AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Final rule.

SUMMARY:

This amendment adopts a new airworthiness directive (AD), applicable to all Boeing Model 737-200 series airplanes modified by Supplemental Type Certificate (STC) ST00516AT, that requires removal of the in-flight entertainment (IFE) system installed per that STC. This action is necessary to eliminate the possibility that the airplane crew could be unable to remove power from the IFE system during a non-normal or emergency situation, which could result in the airplane crew's 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 April 19, 2004.

The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of April 19, 2004.

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 737-200 series airplanes modified by Supplemental Type Certificate (STC) ST00516AT was published in the Federal Register on September 4, 2003 (68 FR 52539). That action proposed to require removal of the in-flight entertainment (IFE) system installed per STC ST00516AT.

Comments

Interested persons have been afforded an opportunity to participate in the making of this amendment. Due consideration has been given to the 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 4 Model 737-200 series airplanes of the affected design in the worldwide fleet. The FAA estimates that 2 airplanes of U.S. registry will be affected by this AD, that it will take approximately 1 work hour per airplane to accomplish the required actions, and that the average labor rate is $65 per work hour. Based on these figures, the cost impact of the AD on U.S. operators is estimated to be $130, or $65 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.

Applicability: Model 737-200 series airplanes modified by Supplemental Type Certificate (STC) ST00516AT, certificated in any category.

Compliance: Required as indicated, unless accomplished previously.

To eliminate the possibility that the airplane crew could be unable to remove power from the in-flight entertainment (IFE) system during a non-normal or emergency situation, which could result in the airplane crew's inability to control smoke or fumes in the airplane flight deck or cabin, accomplish the following:

Removal of IFE System

(a) Within 18 months after the effective date of this AD, remove the IFE system installed by STC ST00516AT per the procedure in Kosola and Associates Service Bulletin 2002-1, dated July 16, 2003. The procedure includes disconnecting the power line that leads from the IFE system control unit to the P6 panel, capping and stowing all related wiring or removing related wiring from the airplane, removing the IFE system circuit breaker from the P6 panel, and removing all components of the IFE system from the airplane.

Inspections Accomplished per Previous Issue of Service Bulletin

(b) Removal of the IFE system installed by STC ST00516AT before the effective date of this AD per Kosola and Associates Service Bulletin 2002-1, dated June 5, 2002, is considered acceptable for compliance with paragraph (a) of this AD.

Parts Installation

(c) As of the effective date of this AD, no person may install an IFE system approved by STC ST00516AT on any airplane.
