Biz AV’s AD Watch
Dassault Falcon 50
The FAA is proposing the adoption of a new Airworthiness Directive (AD) that is applicable to certain Dassault Model Mystere-Falcon 50 series jets. This proposal would require applying PR (fuel tank sealant) and installing PR patches over the internal side panel recesses of the left-hand and right-hand feeder tanks at certain frames and stringers. The FAA claims this action is necessary to prevent fuel ignition in the event of a lightning strike and consequent uncontained rupture of the fuel tank(s).
