Default Question for the Turbine pilots.

We have a doctor who just bought a 206 and after less than a month the
chopper has been sent for a new engine. I heard he had a "Hot Start" and
burned out the engine.

While I'm both fixed wing and helicopter certified I have zero
experience with jets so what did he do? And what's it gonna cost him?

Default Question for the Turbine pilots.

The indication of a hot start is when the TOT (turbine outlet temp) runs
away and goes far too high. Internally its casued when the flameball does
not form correctly as a result of too much fuel, too high of a pre-existing
temperature, or incorrect/sufficient airflow. It requires an inspection and
if he melted enough stuff it could cost around $90,000.

Well they yanked off the rotor blades and put the 206 on a truck so my
bet is he burnt up what could be burnt.

He must be very new to turbines. Had to be more than a hot start, must
have been a fire. Hot start usually would just require inspection of the
burner can. Removing can and power turbine would probably be something a
mechanic could do on site in a few hours and ship to facilitate the
inspection. Moving the complete helicopter is a waste unless being
returned to seller as a warranty return. A simple hot start only
requires a flight test procedure and at the worst can be flown to a
repair facility with in reasonable distance.

Wow,

"..at the worst can be flown..." ? WTF DUDE!. Are you crazy?

I don't want to be harsh, but if you do have a hot start call a factory
authorized repair station for your engine or aircraft (in this case Rolls
Royce / Bell) and follow THEIR advice. DO NOT FLY YOUR MACHINE unless you
get sage wisdom and authorization from one of these.

Sorry, I disagree (with that very last part). I've released a lot of
aircraft as "Certified Safe for Flight" and I would NOT allow even a one-way
flight after an event like that. If the bird is down, it's DOWN. Aircrew
lives depend on my signature and I don't take that lightly.

They can 'fly' it over on the back of a trailer.
