Airworthiness Directive 04-25035
one-timeAirworthiness Directives; Airbus Model A330, A340-200, and A340-300 Series Airplanes
What this AD requires
This amendment adopts a new airworthiness directive (AD); applicable to certain Airbus Model A330, A340-200, and A340-300 series airplanes; that requires inspecting the ram air turbine (RAT) actuator to determine its serial number; and re-identifying the RAT actuator, inspecting the RAT actuator to determine whether the rotary solenoids are in the correct position, and replacing the RAT actuator, as applicable. This action is necessary to prevent failure of the RAT actuator to deploy when necessary during flight, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
Which aircraft AD 04-25035 applies to
Whether AD 04-25035 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.
