Airworthiness Directive 2015-06-04

What this AD requires
We are superseding Airworthiness Directive (AD) 2011-13-07 for all Dassault Aviation Model FALCON 7X airplanes. AD 2011-13-07 requires revising the airplane flight manual (AFM) to include a procedure to power off a radio-altimeter or revert to the correct radio-altimeter output. This new AD requires revising the AFM to include a simpler procedure to revert to the correct radio-altimeter output. This AD was prompted by an analysis which showed that AFM procedures could be simplified. We are issuing this AD to ensure that the flightcrew has procedures in the event of a radio-altimeter lock-up, which inhibits the display of warnings along with certain abnormal conditions, during the switch into landing mode during altitude cruise. If not corrected, this could result in the flightcrew being unaware of possible system failures that require immediate action by the flightcrew, leading to possible loss of control of the airplane.
Which aircraft AD 2015-06-04 applies to
Applies to all serial numbers.
Whether AD 2015-06-04 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.
