WARNING
If fire persists after engine shutdown and is contained within the engine inlet area, discharge ground bottle extinguishing
agent into engine inlet. Failure to comply may result in death or injury to personnel and/or damage to aircraft or
equipment. If fire is within engine compartment, do not discharge the ground bottle extinguishing agents into engine inlet
unless fire is self-sustaining or spreading into aircraft. Failure to comply may result in death or injury to personnel and/or
damage to aircraft or equipment. If fire is in fuselage area, do not motor engine since motoring may supply added fuel to
fire. Failure to comply may result in death or injury to personnel and/or damage to aircraft or equipment.
