Airworthiness Directive 97-28320
one-timeAirworthiness Directives; Airbus Model A300, A310, and A300-600 Series Airplanes
What this AD requires
This amendment adopts a new airworthiness directive (AD), applicable to all Airbus Model A300, A310, and A300-600 series airplanes, that requires performing a ram air turbine (RAT) extension test; removing and disassembling the RAT uplock mechanism; performing an inspection to detect corrosion of the RAT uplock mechanism, and replacement with a new assembly, if necessary; and cleaning all the parts of the RAT control shaft and its bearing component parts. This amendment is prompted by reports indicating that the RAT did not extend during ground testing, due to corrosion in the uplock pin/shaft and the needle bearing of the RAT. The actions specified by this AD are intended to detect and correct such corrosion of the RAT, which could result in failure of the RAT to deploy and subsequent loss of emergency hydraulic power to the flight controls in the event that power is lost in both engines.
Which aircraft AD 97-28320 applies to
applicability derived from the AD summary — confirm the model/serial from the records
Whether AD 97-28320 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.
