Plain English Summary

2/10 complexity

What it is: A mandatory safety directive requiring a specific mechanical modification to certain aircraft engines.

Who it affects: Owners and operators of Pratt & Whitney R1340-S3H1-G series engines (a type of radial piston engine commonly found in older agricultural and utility aircraft like the Commonwealth Ceres).

What you must do: Modify the propeller oil feed pipe (the tube that delivers oil to the propeller's pitch-change mechanism) according to Commonwealth Aircraft Corporation Service Bulletin No. 41.

When:

Installed engines: Before installing the engine in an aircraft following any overhaul completed after 2 November 1967
Spare engines: Before installing the engine in an aircraft after 2 November 1967

Why it matters: This prevents potential oil starvation or leaks in the propeller system that could cause propeller malfunction or engine failure during flight.
