Lycoming Woes Continue: 5100 Crankshafts To Be "Retired"




But the mandatory service bulletin leaves out O-320's and O-235's.

One wonders if Teledyne is getting its alloys from the same source. I doubt
it.


Just guessing here, but aren't the O-235 adn O-320 cranks solid rather than
hollow (for constant speed props)?
