AD  issued on electric fuel pumps 

The  FAA issued an airworthiness directive on Sept. 8 requiring the  inspection/replacement of electric fuel pumps on Bombardier-Rotax 912 F series  and 912 S series reciprocating engines. The FAA determined that excessive fuel  pressure could create a deviation in the fuel supply, resulting in engine  malfunction or fuel leakage. Engines utilizing the pumps are commonly installed  in Diamond aircraft, as well as others, the FAA said. As of the effective date  of the AD, owners must remove, and are prohibited from installing, fuel pumps  with part numbers 892230, 892232, 892235, 892236, 892540, or 892545, at the next  maintenance or within the next 25 hours of engine operation, whichever occurs  first. The FAA estimates that 0.5 hours of work will be required for compliance.  Required parts will cost about $650. For more information, download the  AD.

These engines are the certified versions, that's why the FAA has issued an AD. Rotax had previously issued an SB on pumps for everyone else quite some time ago. They had many of us replace our fuel pumps. This is why you should set up your fuel pump in parallel instead of series.

Roger,

Any chance this pump is the Facet a lot of us are using?

Thanks, Paul

Hi Paul,



Yes the Facet pump is the most common here in the US. I'm sure there may be others. Everyone should have checked the Rotax SB and then your pump serial number to see if you were in the recall bunch. There were a lot of them. Rotax has said when they come out with items like this only about 5%-10% take advantage of a new item offered or most don't ever read the SB's. My new Rotax pump was free so it was just the labor to put it on and I had that part covered.    



If you have an electric pump in series it really would be better in parallel or just don't run it unless there is a real need, like your engine is dying or sputtering.
