Rotax Service Bulletin

[DeltaHotel]

I just saw a paragraph in Sport Avaition about a Rotax SB about Flywheel hub washers, part number 944072. It seems that some washers are too hard and are subject to cracking. The engine serial numbers are listed in the SB. The SB can be found at www.SportAviation.org.

Some further discussion in this thread from last month:

Bottom line...none of the engines sold by Vans are effected by the bulletin.
