Plain English Summary

2/10 complexity

This is a mandatory safety order from the Civil Aviation Safety Authority (CASA) requiring an immediate fix to the carburettor air duct (the tube that feeds air into the engine's fuel system) on specific agricultural aircraft.

Who it affects:

Owners and operators of Schweizer (Grumman) G-164A Ag-Cat aeroplanes with serial numbers 401–406, 408–417, 419, and 420

What you must do:

Modify the carburettor air duct according to Grumman Service Bulletin No. 37 (the manufacturer's official repair instructions)
Do this immediately (the legal term used is "forthwith")

Why it matters: Problems with carburettor air ducts can cause engines to run poorly or fail completely. This directive ensures these specific aircraft receive a critical safety upgrade to prevent dangerous in-flight engine issues.
