12 procedures
- 1OEI flight conditionESTABLISH
- 2Affected engineIDENTIFY
- 3Single engine emergency shutdownPERFORM
- 4LAND AS SOON AS PRACTICABLE
- 5Indications - slight jerk in the yaw axis nose left, possible change in noise level
- 6Indications - affected engine shows ENG FAIL, ENG OIL P, FUEL PRESS and GEN DISCON cautions and instruments indicate power loss
- 1ENG MAIN switch (affected engine)IDLE, check indications, then OFF
- 2If there is an indication that the engine is still running - turn the respective TWIST GRIP to the minimum fuel stop, verify the correct engine, then shut off
- 3Before an inflight single engine emergency shutdown, determine if the situation will allow for OEI flight
- 4Make certain the controls of the affected engine are selected and the collective lever is adjusted to maintain the normal engine within OEI limits
- 5Leave the FADEC switch ON - switching it off will raise a FADEC MINR caution on the remaining engine due to missing parameter redundancy
