Hello Paul, et al-

Putting together our paperwork for the fine folks from the FAA.  Trying to
develop what the in-flight emergency procedures for the engine ought to be &
I would like to hear your thoughts as well as those of the folks who are
currently flying.  I had a conversation with Bob White the other day about
the loss of his rotary BD-4 due to engine issues at 3.8 hours TT, so before
we start test flying I'd like to develop a solid list of plans A, B, C and D
(etc) in case things suddenly get quiet.

If an injector were to fail -- how would we tell?  Ditto for an igniter
failure?  Could we tell them apart?

Here's the beginnings of my fault list -- feel free to modify ruthlessly...

Engine starts Running Rough:

1) Check fuel pressure & select BOTH on fuel pumps
2) Check manual mixture setting & ensure 12:00; try 9:00 / 3:00 for
improvement.  If none, return to 12:00
3) Check Controller setting.  Switch to other controller.  If no
improvement, return to "A" (Best Power) controller
4) Check rotor EGTs -- are they unbalanced?
4A) Check Primary injector bank ON.  Disable PRIMARY injector bank --
immediately re-ENABLE if no improvement
4B) Check Secondary injector bank ON.  Disable SECONDARY injector bank --
immediately re-ENABLE if no improvement
5) Check Igniters on BOTH.  Try LEADING only, then TRAILING only.

Be sure you have fuel in the tanks.
Check the battery voltage.
