Airworthiness Directive 2003-04-25
one-timeAirworthiness Directives; Dowty Aerospace Propellers, Models R354, R375, R389, and R390 Propellers
What this AD requires
This amendment adopts a new airworthiness directive (AD), that is applicable to Dowty Aerospace Propellers, R354/4-123-F/13, R354/4- 123-F/20, R375/4-123-F/21, R389/4-123-F/25, R389/4-123-F/26, and R390/ 4-123-F/27 propellers. This amendment requires a one-time inspection of the hub joint mating surfaces for fretting. This amendment is prompted by reports of fretting on the joint mating faces of propeller hubs. The actions specified by this AD are intended to prevent failure of the hub due to loose hub through bolts.
Which aircraft AD 2003-04-25 applies to
Applies to propeller hubs received from Dowty Aerospace Propellers that have been disassembled since receipt (loose hub through bolts, per Dowty MSB SF340-61-96); hubs never disassembled since receipt require no action. Specific propeller model designations are not present in the extracted text.
Whether AD 2003-04-25 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.
