Airworthiness Directive 2002-22-08
one-timeAirworthiness Directives; Hartzell Propeller Inc., Model HD-E6C-3( ) Propellers
What this AD requires
This amendment adopts a new airworthiness directive (AD) that is applicable to Hartzell Propeller Inc. model HD-E6C-3( ) propellers. This action requires replacement of the current design propeller blade thrust bearing with a new design propeller blade thrust bearing and visual and eddy current inspection (ECI) of propeller hubs for cracks. This amendment is prompted by reports of fractured thrust bearings observed during disassembly, one or more blades becoming jammed in position during operation, pitch change fork fractures causing loss of blade pitch control, and excessive vibration. The actions specified in this AD are intended to prevent loss of aircraft control due to loss of blade pitch control, inability to fully feather the propeller, hub fracture, and blade release.
Which aircraft AD 2002-22-08 applies to
Applies to Hartzell HD-E6C-3( ) propeller models with blade thrust bearings P/N C-2882-1, C-2882-2, or C-7075 (per Hartzell ASB HD-SB-61-026 and HD-ASB-61-023 Rev 1); affected bearings must be replaced with P/N C-7438, and hub must be inspected for cracks.
Whether AD 2002-22-08 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.
