Start Preamble

AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Dassault Model Mystere-Falcon 900 series airplanes. This proposal would require revising the Abnormal Procedures section of the airplane flight manual to advise the flightcrew to avoid use of certain display modes during approaches. This proposal also would require replacing certain symbol generators of the Electronic Flight Information System (EFIS) with modified symbol generators. This action is necessary to prevent distraction of the flightcrew during a critical phase of flight due to certain EFIS displays flashing or going blank, which could result in loss of control of the airplane. This action is intended to address the identified unsafe condition.

Discussion

The Direction Générale de l'Aviation Civile (DGAC), which is the airworthiness authority for France, notified the FAA that an unsafe condition may exist on certain Dassault Model Mystere-Falcon 900 series airplanes. The DGAC advises that, in certain phases of flight, especially during approach, the quantity of data to be processed may lead to saturation of the processors of certain symbol generators used by the Electronic Flight Information System (EFIS). This may cause the EFIS display to flash or go blank. This condition, if not corrected, could result in distraction of the flightcrew during a critical phase of flight, which could result in loss of control of the airplane.

Explanation of Relevant Service Information

Dassault has issued Temporary Change No. 86 to the Abnormal Procedures section of the Mystere-Falcon 900 Airplane Flight Manual (AFM). That Temporary Change advises the flightcrew that certain EFIS displays may blink or blank due to overload of certain symbol generators, and advises the flightcrew to avoid using certain display modes during approaches to decrease the load on the display processor.

Dassault has also issued Service Bulletin F900-281, Revision 1, dated October 3, 2001. That service bulletin describes procedures for replacing certain symbol generators with modified symbol generators. Accomplishment of the actions specified in the service bulletin is intended to adequately address the identified unsafe condition.

The DGAC classified the temporary change to the AFM and the service bulletin as mandatory and issued French airworthiness directive 2001-466-033(B), dated October 3, 2001, to ensure the continued airworthiness of these airplanes in France.

FAA's Conclusions

This airplane model is manufactured in France and is type certificated for operation in the United States under the provisions of § 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, Start Printed Page 68300the DGAC has kept us informed of the situation described above. We have examined the findings of the DGAC, reviewed all available information, and determined that AD action is necessary for products of this type design that are certificated for operation in the United States.

Explanation of Requirements of Proposed Rule

Since an unsafe condition has been identified that is likely to exist or develop on other airplanes of the same type design registered in the United States, the proposed AD would require revising the Abnormal Procedures section of the AFM to advise the flightcrew to avoid using certain display modes during approaches, and accomplishing the actions specified in the service bulletin described previously, except as discussed below.

Difference Between Proposed AD and Referenced Service Bulletin

Operators should note that, although the Accomplishment Instructions of the referenced service bulletin describe procedures for completing and returning a card recording compliance with the service bulletin, this proposed AD would not require this action.

Cost Impact

We estimate that 93 airplanes of U.S. registry would be affected by this proposed AD.

It would take approximately 1 work hour per airplane to accomplish the proposed AFM revision, at an average labor rate of $65 per work hour. Based on these figures, the cost impact of this proposed action on U.S. operators is estimated to be $6,045, or $65 per airplane.

It would take approximately 1 work hour per airplane to accomplish the proposed replacement, at an average labor rate of $65 per work hour. Required parts would be provided by the parts manufacturer at no charge. Based on these figures, the cost impact of this proposed action on U.S. operators is estimated to be $6,045, or $65 per airplane.

The cost impact figures discussed above are based on assumptions that no operator has yet accomplished any of the proposed 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 proposed herein would 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 proposal would not have federalism implications under Executive Order 13132.

For the reasons discussed above, I certify that this proposed regulation (1) is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) if promulgated, 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 copy of the draft regulatory evaluation prepared for this action is contained in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.
