Crankshaft AD - Fake news!

Post by 6643 »

This AD and final rule is effective February 23, 2023 and affects any crankshaft assembly on a Continental Engine.
While there is only one way to interpret this statement, it is in fact wrong. The AD applies only to crankshafts with removable counterweights, and I will go out on a limb and say that excludes all horizontally opposed 4 cylinder engines right off the bat. It is further restricted to only those crankshafts serviced since sometime in 2021, or, apparently, manufactured within a similar time frame.

I guess they were going for sensationalism in the headline...

I quickly read the AD and found that it only applied to larger Continentals.

Crazy situation.
1. Yes only engines with counterweights......(i.e. large bore engines)
2. Continental isn't saying why, what, when how........but were I a guessing man......somebody at the factory didn't install the retaining C clip properly. Sure has grounded a bunch of aircraft!
