Unsafe Condition
The oil level in the oil tank can fall below the minimum level required to sustain proper engine lubrication, leading to inadequate venting of the lubrication system and potential damage to the engine valve train, which can result in an in-flight engine failure and forced landing.

Required Actions
Remove the existing part number oil dipstick (P/N 956150) and install a new serviceable dipstick with a different part number. Inspect the valve train and properly vent the lubrication system before the next engine start for engines with 50 hours or less time-in-service since the engine had the oil system opened, oil changed using improper procedures, or the propeller rotated more than one turn in the wrong direction. Thereafter, vent the lubrication system and inspect for correct venting of the hydraulic valve tappets before starting the engine after specific maintenance actions.
