Plain English Summary

2/10 complexity

What this does: This is a safety directive (Airworthiness Directive) requiring owners of specific Schweizer G-164 "Ag-Cat" agricultural aircraft to modify the fuel shut-off control installation.

Who it affects: Owners and operators of specific Schweizer (Grumman) G-164A, G-164B, G-164C, and G-164D aircraft with specific serial numbers:

G-164A: serial numbers 1726A to 1730A
G-164B: serial numbers 335B to 659B
G-164C: serial numbers 1C to 44C
G-164D: serial numbers 1D to 22D

Why it matters: The manufacturer discovered that forcefully turning the fuel cock to the "On" position can cause it to rotate too far into an unmarked "Off" position. This could accidentally cut fuel to the engine during flight, causing engine failure.

What must be done: Unless already completed, operators must carry out the modification specified in Schweizer Service Bulletin No. 78 (or follow FAA AD 82-07-04) within 100 hours of flying time after 30 June 1982.
