DrZoos Posted October 7, 2014 Share Posted October 7, 2014 http://legacy.rotaxowner.com/si_tb_info/serviceb/sb-912-065.pdf Seems some floats are absorbing fuel and hence changing the weight... Affects Rotax float replacements and engines since approx 2012 Every 25 hour check needed till a fix is found... Link to comment Share on other sites More sharing options...

rankamateur Posted October 8, 2014 Share Posted October 8, 2014 All affected motors have serial 4 XXX XXX, must all be certified, my 912ULS is serial 6 781 3XX, so might not be a problem to many of us. Link to comment Share on other sites More sharing options...

I know of it happening to a 914 fitted to a Gyro so seems to be a problem on all series! Link to comment Share on other sites More sharing options...

Downunder Posted October 8, 2014 Share Posted October 8, 2014 From ULS 6 780 228 onwards. Just missed out with my 6 779 XXX thankfully, but got caught up in the "suspect" crank debacle......... Rotax seem to be having ongoing quality control problems. Sounds like bean counters chasing the cheapest bidder/supplier....... Link to comment Share on other sites More sharing options...

Thanks Aro, that is the one I needed, wouldn't have wanted to start my new motor without complying with the mandatory SB. I wonder how many hours I could have flown it no condition?

facthunter Posted October 8, 2014 Share Posted October 8, 2014 Float carbs are a risk anyhow, but with suspect floats, it goes to a new level. If there is a guaranteed part available I would fit it if there is any doubt whatever. Nev Link to comment Share on other sites More sharing options...
Old Koreelah Posted October 9, 2014 Share Posted October 9, 2014 Surely the carbs are delivered by Bing complete with floats? If that's the case, other users- like Jabiru- are also affected. 2 Link to comment Share on other sites More sharing options...

Guest Maj Millard Posted October 14, 2014 Share Posted October 14, 2014 "and or fuel leakage". Could that have been the problem for old mate in powered glider? Robes.....had a long chat with pilot the other night....scary stuff, he said he side-slipped down as long as he could until the heat got to his legs. Also said everything around him got burnt including the headsets he was wearing !....but not him. He was at 4500 on limb to 7500.... Luckily he was not there yet....from speaking with him I don't think the floats were the cause....this was a fairly old 80 HP A model 912.......GFA are investigating for cause.

Guest Maj Millard Posted October 14, 2014 Share Posted October 14, 2014 What expertise does GFA have with engines? Good question, however like most investigating teams I would expect they would seek whatever assistance the may require. It doesn't appear that this was battery related in any way, which certainly was an initial concern. It is always very important however that a ground run and fuel/oil leak check be carried out prior to cowling up after any. Work has been done on those systems.
