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, NorthwestMountain 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. ## Affected data sheets (1) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS A33EU](https://openairdocs.org/tcds/A33EU): Dassault Aviation; names 1 of 1 models: Falcon 10 ## Registered aircraft it may apply to (OpenAirDocs) Matched by airframe and engine model; the AD's applicability may narrow it by serial number, part number or equipment. - Aircraft: 59 (59 by airframe model, 0 by engine model) - Makers: Dassault-Breguet 56, Avion Marcel Dassault Breguet 2, Avions Marcel Dassault Breguet 1 Models with the most aircraft: - [Dassault-Breguet FALCON 10](https://openairdocs.org/model/dassault-breguet-falcon-10): 56 aircraft (airframe model) - [Avion Marcel Dassault Breguet FALCON 10](https://openairdocs.org/model/avion-marcel-dassault-breguet-falcon-10): 2 aircraft (airframe model) - [Avions Marcel Dassault Breguet FALCON 10](https://openairdocs.org/model/avions-marcel-dassault-breguet-falcon-10): 1 aircraft (airframe model) All 3 models: https://openairdocs.org/ad/87-24-10/models.md Every aircraft: https://openairdocs.org/ad/87-24-10/aircraft.md Its text cites no advisory circulars or STCs. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
