Grounded plane
Hi my plane (a 2020 colt with 200 hours) is currently being ferried from Florida to Texas. After a routine stop for gas , the pilot experienced a 2000 RPM drop on the right mag during the run up. A local mechanic on the field (not a Rotax expert) has been attempting to diagnose the problem, but appears to be having trouble localizing. At first they thought is was related to plugs, then one of the ignition coils, both have since been ruled out. Any ideas please
Re: Grounded plane
You don't say which engine your plane has, but let's assume a 912ULS. If the mechanic checked the "mags" he or she clearly doesn't understand electronic ignition. How were the ignition coils and plugs eliminated? Faulty ignition modules generally present as difficulty starting, not an RPM drop during run-up.

Re: Grounded plane
Ops, my apologies. Yes its a 921ULS. I am not exactly sure what they have done other than what I have put down here. Just looking to see if there is anything glaring based upon the symptoms they experienced.
