Mandatory ALERT Service Bulletin: Inspection and Replacement of Oil Spray Nozzle for ROTAX® Engine Types 912 i, 915 i, and 916 i (Series) SB-912 i-016 / SB-915 i-016 SB-916 i-006

Titus,

In addition to what RW stated, failures of alternator (stator) A are very uncommon. This is because alternator A is right-sized (220 watts) for the engine loads and the regulator and stator don't produce as much heat. Alternator B has been a problem because it has to be sized for a wide range of airframe loads (420 Watts) and often the shunt regulator is working harder to maintain the correct voltage, which also ends up adding some heat into the stator.  You will note that that all of the Alternator / Regulator related SB's are in reference to Alternator B. 

I cannot locate the 19 page document referenced in the video.  All I can find are the two page bulletins.

Where is the document referenced in the video?

The two page document is you are looking at the non-certified SB. When searching for the whole document look for the certified engine document. 915iS VS 915iSc on the drop for the engine type.

Thank you so much.  I've been looking for it for two hours.  Do you have an affected engine?

Looks like you are good!
