Airworthiness Directive 2016-10-16
one-timeAirworthiness Directives; Dassault Aviation Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model MYSTERE-FALCON 900 airplanes, FALCON 900EX airplanes, and FALCON 2000EX airplanes. This AD was prompted by a report that during a test flight, it was found that the yaw damper on the takeoff roll can increase the Minimum Control Speed on Ground (Vmcg). This AD requires revising the airplane flight manual (AFM) to incorporate procedures for the flightcrew to check that the yaw damper is set to "off" before takeoff. We are issuing this AD to ensure that the flightcrew has procedures to set the yaw damper to "off" before takeoff, which, if activated, could result in reduced control of the airplane if one engine were to fail during takeoff.
Which aircraft AD 2016-10-16 applies to
MYSTERE-FALCON 900: all serial numbers. FALCON 900EX: all serial numbers except airplanes with 'EASy II' 2nd certification avionics (production Modification M5595, or in-service SB F900EX-400/F900EX-414), with listed exceptions for certain earlier SB revisions that remain affected. FALCON 2000EX: all serial numbers except those with production Modification M3254 or in-service SB F2000EX-300 ('EASy II' avionics).
Whether AD 2016-10-16 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
