Hi! Glenn
Good airmanship necessitates mag. checks every time the engine is shut
down and this is vital towards preventing the incident you relate. There
was an incident just prior to Christmas at Wickenby due to hand propping
to clear flooded carbs when the pilot jumped out without locking the
brakes and switching the mags off. The engine fired up and swung round
into the friends nearby parked plane with the propeller finishing up
chewing the fuselage to bits. (Not Rotax though!)
Whilst the burping procedure is preferable to be done on a long standing
cold engine I would advocate not doing it on a hot engine because
=9Cmurphys law=9D goes a long way to have it happen.

Subject: Europa-List: burping the 912
There is a thread running in the yahoo canard list concerning a recent
fatal (lycoming or similar I suspect) hand-propping incident at
Gillespie Field /CA, which prompts me to this posting. There must have
been a lot of accumulated experience here and elsewhere with the
'oil-burp' procedure for the 912. Does anyone know of any accidental
starts? Sure, this query belongs on the rotaxEngine list perhaps - i'm
not yet subscribed to that - on my list to do. Quick look - i found
nothing.
