NOTE
: RE-IGN
indicator light will stay on until manually reset. The reignition system will
continue to function normally whether reset or not.
If the N
R
or N
1
tach generator fails, the
RE-IGN
indicator will light and the igniter
will be energized until the engine is shut down or the reignition system is
disarmed (circuit breaker pulled). The reignition system is armed under all
operating conditions.
Failure or deactivation of the engine failure/low rotor rpm warning system,
renders the reignition system inoperative. Under certain failure conditions, the
ARMED
light may stay on.
Pulling out the ENG OUT circuit breaker will disarm the Auto
Reignition system.
Following any activation of reignition system caused by flameout from snow,
ice or water ingestion, inspect engine in accordance with the appropriate Alli−
son 250 Series Operation and Maintenance Manual.
Yawing of the helicopter may or may not follow an engine flameout and reigni−
tion sequence. The magnitude of the yaw will depend on forward speed and
power being used.
