REGULATORY TEXT:   89-06-05 R1 AVIONS MARCEL DASSAULT- BREGUET AVIATION (AMD-BA): Amendment 39-6151 as revised by Amendment 39-6412. Docket No. 89-NM-142-AD.

Applicability: Model Mystere Falcon 50 and 900 series airplanes as listed in AMD-BA Service Bulletins F-50-208, Revision 1, and F-900-52, Revision 1, both dated July 25, 1989, certificated in any category.

Compliance: Required as indicated, unless previously accomplished.

To prevent inability to open the main landing gear (MLG) door for MLG emergency extension, accomplish the following:

A. Prior to the accumulation of 1,000 landings on the MLG door emergency unlocking pin, or within 7 days after March 24, 1989 (the effective date of AD 89-05-05, Amendment 39-6151), whichever occurs later, verify the integrity of the MLG door emergency unlocking system by operating the manual opening system, in accordance with the instructions in the AMD-BA Falcon 50 Maintenance Manual Work Card 480.0, paragraph 3, or Falcon 900 Maintenance Procedure No. 32-120, as applicable. If the unlocking pin is broken or damaged, replace the pin with a serviceable pin of the same part number prior to further flight.

B. Upon accumulation of 2,000 landings on the MLG door emergency unlocking pin, or within 50 landings after the effective date of this AD, whichever occurs later, repeat the inspection described in paragraph A., above, and continue to perform this inspection at intervals not to exceed 50 landings.

C. Following the replacement of any unlocking pin with a new pin, repeat the inspections required by paragraphs A. and B., above.

D. Prior to the accumulation of 2,000 landings on the airplane, or within 120 days after the effective date of this AD, whichever occurs later, modify the emergency release mechanism of each MLG door uplock unit in accordance with AMD-BA Service Bulletin F50-208 (F50-32-18), Revision 1, or F900-52 (F900-32-4), Revision 1, both dated July 25, 1989. Accomplishment of this modification constitutes terminating action for the inspections required by paragraphs A. through C. of this AD.

E. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Standardization Branch, ANM-113, FAA, Northwest Mountain Region.

NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector (PMI), who will either concur or comment and then send it to the Manager, Standardization Branch, ANM-113.

F. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD.

All persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to Falcon Jet Corporation, Customer Support Department, Teterboro Airport, Teterboro, New Jersey 07608. These documents may be examined at the FAA, Northwest Mountain Region, Transport Airplane Directorate, 17900 Pacific Highway South, Seattle, Washington, or Standardization Branch, 9010 East Marginal Way South, Seattle, Washington.

This AD revises Amendment 39-6151, AD 89-06-05.

This amendment (39-6412, AD 89-06-05 R1) becomes effective on January 12, 1990.
