TWO ENGINE FLAMEOUT EXPANDED CHECKLIST
This procedure is to be used if thrust or throttle response is lost from both engines at any speed or altitude in the aircraft’s operating envelope. The probability of a successful start is improved at altitudes below 24,000 feet and speeds between 180 and 320 KIAS.
During descent, this condition may first be indicated by illumination of the GEN OFF or OIL PRESS LOW lights. If these lights illuminate, check N2 and EGT to verify engine operation.
IMMEDIATE ACTION
EMER PWR Switch ................................................................... ON ENG IGN Switch ................................................................... OVRD
The immediate action items should be accomplished expeditiously to effect an immediate restart before the engines have spooled down completely. If this emergency is the result of flight in areas of heavy/extreme precipitation, the engines may not start until after leaving the precipitation. Repeated attempts at restarting the engines may be necessary once clear of heavy rain, sleet, or hail.
SECONDARY ACTION
CABIN ALT Control Lever.........................................MANUAL (DOWN)
This locks the outflow valve in position for manual operation. IF Aircraft Altitude is Above 10,000 Feet MSL:
Outflow Valve Position Indicator............................... VALVE CLOSE
Push down and roll the outflow valve full forward.
Oxygen Masks, Regulators .................................................. ON, 100%
Prepare for the cabin pressure to rise above 10,000 feet.
Airspeed ......................................................MINIMUM MANEUVERING
(NOT LESS THAN 170 KIAS) Throttles.............................................................................................. IDLE ENG Anti-Ice Switches...........................................................................ON BATT Switch .................................................................... ON & LOCKED
(Continued)
START PUMP Switch.................................................................... ON
Fuel Boost Pump Switches .................................................... ALL ON
GEN Switches............................................................................... OFF
ENG HYD PUMP Switches ......................................................... OFF
FUEL Levers..................................................................................ON
FUEL X-FEED Lever .................................................................. OFF
IF Neither Engine Starts:
Note: If two engine flameout was caused by fuel starvation in left and right main tanks with fuel in center wing tank, optimum attitude for scavenging fuel out of the right main tank for APU or right engine is 0. pitch and 1.5. right wing up.
APU MASTER Switch ................................. START, RELEASE
Note: Attempt APU start regardless of altitude and airspeed. IF APU Starts:
L and R APU BUS Switches............................................. ON
AUX & TRANS HYD PUMP Switches............................ ON
Continue engine start attempts. IF One or Both Engines Start:
GEN Switch (Operating Engines)........................................... ON
ENG HYD PUMP Switch (Operating Engines) ...................... HI
AUX & TRANS HYD PUMP Switches .................................. ON
CABIN ALT Control Lever ...................................... AUTO (UP)
OR START PUMP Switch........................................................... OFF
ENG Anti-Ice Switches ...................................... AS REQUIRED
ENG IGN Switch................................................ AS REQUIRED
Note: Continue engine and / or APU start attempts until at least two are running (two engines or one engine and the APU). This will provide two generators for electrical power.

Land at nearest suitable airport. Refer to ENGINE FAILURE and
ONE ENGINE INOPERATIVE APPROACH AND LANDING
checklist, this section, if required.
* * * *
IF Neither Engine Starts :
ENG HYD PUMP Switches ..................................................... HI
Continue glide at minimum maneuver speed for configuration. Keep track of altitude and time to go prior to landing. Notify ATC and consider their recommendations in choosing a landing point.
Continue attempts to start an engine or the APU as long as possible without jeopardizing the landing.
Direct Flight Attendants to prepare for crash landing and estimate time remaining.
Depressurize cabin manually and lock cabin aft control wheel in the full aft (open) position prior to landing.
