I was wondering...how common is a starter generator problem in the Israel IAI-1124 Westwind? I am asking b/c in the last 4-6 months we have had 3 seperate incidents at AEX where a Westwind has come in and had to stay due a "starter generator problem." I've been out there for 4 years now, and have seen many Westwinds....but not this many starter problems!
Any ideas or thoughts anyone?

I work on my own vehicles so maybe some of that knowledge might help you out.
My guess would be location on the engine as far as heat goes. If your engine compartment on your car gets to hot, that alternator/ generator is pulling in all that heat through the built in fan and then trying to cool itself (not gonna happen) so wires get hot and eventually fatigue to the heat and vibration. The bearings would tend to go the same way, heat fatigue and then failure.
I'd kinda be curious as to what you found the problem to be, and what symptoms.
edit: left some working out.

Well, sometimes planes are more likely to break due to their location. For example, if you land in Miami, Daytona, Cancun, etc. planes are much more likely to breakdown than po-dunk Oklahoma, or Wendover Utah. (don't rag on me, I've lived in both states and liked them both).
That being said, the company I work for carries spare starter generators in some of the aircraft we fly. The notion is that it's better to have the parts on hand for an easy swap than to have the airplane grounded in an obscure location.
It hasn't happened to me, but yes, starter problems seems to be one of the more common failure modes for turbine aircraft.
PS.. I think the Westwind has TFE331s...our planes don't..

I work on a Westwind 1124 ( N525XX, s/n 334) and it has yet to have a start/gen problem that was not detected way before it caused a cancelled flight. Most issues relating to the start/gen are the brush wear, shearing of the spline shaft, and cleanliness of the electrical connections (no corrosion), as well as failure to parallel outputs (voltage to the essential bus) Ours is on the CAMP (Computerized Aircraft Maintenance Program) and periodic work cards are issued to inspect all of these areas for wear and potential problems. Some operators do not elect to do as much preventive maintenance, and therefore the potential for failure goes up. I know several people who work on these and have had no frequent start/gen issues either. However, the Westwind is known for leaking fuel at the wing fasteners around the main gear, and from the fuse tanks as well. Hope this helps.
