Unsafe Condition
Structural damage to aircraft frames and skin in the vicinity of the electrical grounding connection for the air conditioning freon compressor motor due to electrical arcing across a loose grounding connection.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Conduct a visual inspection and resistance test of the electrical grounding connection on frame 35 within 30 days after the effective date, and every 30 days thereafter. If resistance exceeds limits, repair the grounding connection before further flight. If resistance cannot be obtained, install a new grounding cable before further flight. Install a new electrical grounding cable within 4 months after the effective date. Repair any structural damage from electrical arcing prior to further flight as approved by the FAA.

ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 87-24-10 AVIONS MARCEL DASSAULT - BREGUET AVIATION (AMD-BA): Amendment 39-5776. Applies to all Falcon 10 airplanes, certificated in any category, unless AMD-BA modification M736 has been accomplished. Compliance is required as specified, unless previously accomplished. To prevent structural damage to aircraft frames and skin in the vicinity of the electrical grounding connection for the air conditioning freon compressor motor, accomplish the following: A. Within 30 days after the effective date of this AD, and thereafter at intervals not to exceed 30 days, conduct a visual inspection and a resistance test of the electrical grounding connection, located on frame 35, for the air conditioning freon compressor motor. Perform the inspection and test in accordance with the AMD-BA Service Bulletin F10-262, dated December 22, 1986 (reference Maintenance Manual Chapter 20-40-40). 1. If the measured resistance value of the grounding connection bonding exceeds the limits referenced in paragraph B. of the Accomplishment Instructions of the service bulletin, then prior to further flight, repair the grounding connection in accordance with the service bulletin. 2. If the resistance value specified for the grounding connection bonding cannot be obtained, then prior to further flight, install a new grounding cable in accordance with paragraph C. of the Accomplishment Instructions of the service bulletin. B. Within 4 months after the effective date of this AD, install a new electrical grounding cable for the air conditioning freon compressor motor, in accordance with the Accomplishment Instructions of AMD-BA Service Bulletin F10-262, dated December 22, 1986. C. Installation of a new electrical grounding cable for the air conditioning freon compressor motor, in accordance with AMD-BA Service Bulletin F10-262, dated December 22, 1986, constitutes terminating action for the repetitive inspection and testing requirements of paragraph A. above. D. Any structural damage due to the effects of existing electrical arcing across a loose grounding connection identified during the inspections required by paragraph A., above, must be repaired, prior to further flight, in a manner approved by the FAA. 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. F. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections and/or modifications required by 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 the AMD-BA Representative, c/o Falcon Jet Corporation, Teterboro Airport, Teterboro, N.J. 07608. These documents may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or at the Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington. This amendment becomes effective December 29, 1987. FOOTER:
