Airworthiness Directives; Dassault Aviation Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes equipped with certain ram air turbine (RAT) transformer rectifier units (TRUs). This AD was prompted by a report of incorrect design of the TRU part of the RAT system. This AD requires replacing any affected RAT TRU with a modified RAT TRU. We are issuing this AD to prevent loose internal wiring in the RAT generator, which could result in degraded direct current power to essential airplane systems while the RAT is deployed, which could adversely affect continued safe flight and landing of the airplane.

ModelsFALCON 7X

Part-conditional — 5913703.

Applies to all serial numbers, but only airplanes equipped with any ram air turbine (RAT) transformer rectifier unit (TRU) having part number 5913703.

Whether AD 2011-27-06 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:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 2011-27-06 complied with on your aircraft?

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.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
