96.10.11.10 Set FUEL switch to OFF. Turn
electrical power off.
96.10.12 Idle Stop Release Solenoid
The idle stop release solenoid limits minimum
throttle setting for engine to flight idle during
normal or ground run operations. The solenoid
receives power from the 28 VDC Essential bus
through the IDLE STOP circuit breaker. When the
pilot’s IDLE STOP REL button is pressed, the idle
stop solenoid retracts its stop. This allows the
throttle to be actuated further toward OFF position,
thus slowing or stopping the engine.

Release Solenoid
96.10.13.1
Apply electrical power to helicopter
electrical system.
96.10.13.2 On helicopter perform electrical
check as follows:
96.10.13.2.1 Press IDLE STOP RELEASE switch
on pilot collective stick. Verify engine idle stop
solenoid retracts.

Turn electrical power off.
96.10.14 Engine Anti-Icing
The engine anti-icing system consists of the
following components: a hot air solenoid valve
located on the engine inlet housing, an ice
detector probe located in the engine intake air
stream, an ice interpreter mounted in the nose
compartment, a de-ice switch mounted on the
engine control panels and three annunciators on
the master caution panel.
