Summary
We propose to adopt a new airworthiness directive (AD) for all Dassault Aviation Model FAN JET FALCON airplanes; all Model FAN JET FALCON SERIES C, D, E, F, and G airplanes; and all Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. This proposed AD was prompted by a determination that inspections for discrepancies of the fuselage bulkhead are necessary. This proposed AD would require repetitive inspections for discrepancies of the fuselage bulkhead, and repair if necessary. We are proposing this AD to detect and correct discrepancies of the fuselage bulkhead; such discrepancies could result in the deterioration and failure of the bulkhead, which could result in rapid decompression of the airplane and consequent injury to occupants.
