Airworthiness Directive 2023-08-07
one-timeAirworthiness Directives; Allied Ag Cat Productions, Inc. Airplanes
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for Allied Ag Cat Productions, Inc. (Allied Ag Cat) Model G-164A and G-164B airplanes with certain supplemental type certificates (STCs) installed. This AD was prompted by an accident involving an Allied Ag Cat Model G- 164B airplane where the airplane's propeller pitch control (PPC) linkage detached from the PPC of the engine and resulted in an accident that significantly damaged the airplane and injured the pilot. This AD requires installing a secondary retention feature (bolt, washer, and safety wire) on the PPC lever and the PPC assembly. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2023-08-07 applies to
All serial numbers, certificated in any category, but only when a specific STC is installed: Model G-164A with STC SA7769SW, SA7966SW, or SA8720SW installed; Model G-164B with STC SA7546SW, SA7966SW, SA7987SW, or SA8720SW installed.
Whether AD 2023-08-07 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.
