SECTION 4
NORMAL PROCEDURES
EASA Approved
MOTORING (1/2)
To drain fuel accumulated inside the combustion chamber, a motoring procedure is required following an aborted
start.
A 15-second dry motoring run is sufficient to clear any fuel pooled in the engine. The fuel is removed in liquid or
vapor form, through an airflow intended to dry combustion chamber, turbines and exhaust nozzles.
To improve cooling of the bearing cavities and prevent oil coking after shut-down in high OAT [above 35° C (95° F)]
environment, it is recommended to perform a 30-second dry motoring run.
It is possible that no trace of drainage be observed under engine, due to the drainage collector intended to prevent
parking area from contamination.
- - WAIT FOR ENGINE TOTAL SHUT- -DOWN,
- - WAIT AT LEAST 30 SECONDS BEFORE INITIATING A MOTORING.
