TM  1-1520-240-10 9-1-20            9-1-28.  Engine Shutdown with APU or APU Genera- tor Inoperative. CAUTION When the rotors stop turning, no hydraulic pressure is available to motor the engines. In the event of internal engine fire when engine motoring cannot be accomplished, use fire extinguishing equipment as nec- essary to extinguish the fire. Apply external electrical and hydraulic power (if avail- able) and continue with a normal shutdown. If external electrical and hydraulic power is not available, proceed as follows: 1.   No. 2 Engine — Perform a normal shutdown. 2.   All unnecessary electrical switches (except BATT switch) — OFF. 3.   GEN 1 and 2 switches — OFF. 4.   ENG COND 1 lever — GND. Wait until PTIT decreases and then begins to increase; then move the ENG COND 1 lever to STOP. 5.   ENG 1 START switch — MTR until rotors stop or PTIT is below 260_ C. 6.   Normal shutdown — Perform. 9-1-29.  Engine  Oil  —  Low  Quantity/High  Tempera- ture or Low Pressure. A low engine oil quantity condition will be indicated by the lighting of the NO. 1 ENG OIL LOW or NO. 2 ENG OIL LOW caution light. When either oneor both of these cau- tion lights come on, about 2 quarts of usable oil remain in the respective oil tank. If one or both of the caution lights come on, check oil temperature and oil pressure indicators (affected engine) for abnormal indications. If the indication on the oil temperature indicator is high or the indication on the oil pressure indicator exceeds limits, high or low, perform the following: 1.   If engine power is required for flight: Land as soon as possible. 2.   If engine power is NOT required for flight: a.   EMER ENGINE SHUTDOWN — Affected Engine) b.   Land as soon as practicable. 9-1-30.  Engine Chip Detector Caution Light ON. If either NO. 1 or NO. 2 ENG CHIP DET caution light comes on, perform the following: 1.   If engine power is required for flight: Land as soon as possible. 2.   If engine power is NOT required for flight: a.   EMER  ENGINE  SHUTDOWN  —  (Af- fected Engine) b.   Land as soon as practicable. 9-1-31.  Rotor, Transmission, and Drive Systems. WARNING If an interposer block or rotor blade droop stop is not in place, the flight engineer will notify the pilot in command. All non-crew- members will evacuate the aircraft to a safe position. If possible, crew will contact main- tenance  and  attempt  to  engage  interposer block with a high pressure water stream or prepare aircraft for shutdown in such a way as  to  minimize  damage  to  the  aircraft  and components and prevent injury to person- nel. If interposer blocks appear to be in place, the flight engineer will clear the pilot to shut down the first engine. After the first engine is shut down, the flight engineer will observe the rotor blade tip path of the forward and aft rotor heads. A rotor blade drooping signifi- cantly lower than the other blades indicates a  missing  droop  stop.  In  this  case  the remaining  running  engine  condition  lever (ECL)  should  be  advanced  until  sufficient rotor RPM is achieved to lift rotor blades off of droop stops to  insure no  blade contact with airframe and maintenance contacted to prepare aircraft for an emergency shutdown that  will  minimize  damage  to  aircraft  and injury to personnel. 9-1-32.  NO. 1 or NO. 2 ENG XMSN HOT Caution. 1.   EMERG ENG SHUTDOWN. F 2.  Affected engine transmission — Check. 3.   Land as soon as possible.   9-1-33.  Transmission Debris Screen Latches. Trouble developing any of the five transmissions may be indicated by a tripped latch indicator. This information will be presented on the flight engineer’s MAINTENANCE PANEL but will not be shown in the cockpit. If a latch indicator trips, it may be reset once during the flight. If an indicator trips: FWD, COMB, or AFT DEBRIS SCREEN indicator: F RESET/GND/TEST switch — RESET. If indicator does not reset: Land as soon as possible. LEFT or RIGHT DEBRIS SCREEN indicator: F  RESET/GND/TEST switch — RESET.
