Plain English Summary

5/10 complexity

This Airworthiness Directive requires operators of certain Dassault Aviation Mystere Falcon 50 aircraft (serial nos. 222–286, 288, 290, 291) to inspect the double-skin fuel feeder tank seals per the maintenance manual and to carry out corrective work following Dassault Service Bulletin F50-328 R1. CASA revoked the earlier AD and reissued this version.

Inspections must be done before 30 March 2001 and then every 13 months until the modification is completed; the deadline for the corrective action varies by serial number or next “C” check. The measure addresses possible fuel fumes entering the cabin.
