Swapped engine feed lines detected in Dassault Mystere Falcon 50 and 50EX aircraft have led the European Aviation Safety Agency to issue an emergency airworthiness directive ordering immediate inspection of the installation.
The lines found swapped on two in-service aircraft were the No 2 engine fire extinguishing system line and the No 2 engine low-pressure bleed air line. This swap would render the No 2 engine fire extinguishing system ineffective. EASA has ordered operators to inspect the connections of these lines at frame 42 in the rear compartment, according to Dassault service bulletin F50-519.
Inspection was to take place within eight days, and operators are asked to report the findings to Dassault even if they are negative.
