Engine Driven Fuel Pump (Edfp) - Partial Failure; Ditching - Lancair Columbia 400 Information Manual

Columbia 400 (LC41-550FG)
ENGINE DRIVEN FUEL PUMP (EDFP) – PARTIAL FAILURE
(Fuel pressure too high to activate backup pump. Intermittent power – No fuel pump
annunciator)
1. Backup Boost Pump  SET TO ARMED
2. Throttle Control  SET TO FULL OPEN
3. Primer Button ENGAGE AND DISENGAGE (If holding in the primer switch restores
fuel flow/power, the partial EDFP failure is confirmed. Release the switch and proceed to
Step 4.)
4. Mixture Control TOWARDS IDLE CUTOFF (At a fuel pressure of 5.5 psi, the backup
pump should engage, which will restore fuel flow and engine power.)
5. Mixture Control  TOWARDS RICH (Degree of richness depends on altitude; see Chapter
5)

DITCHING

1. Radio MAKE DISTRESS TRANSMISSION (Set transponder code 7700 and transmit a
Mayday distress condition. Give estimated position and intentions.)
2. Loose Objects  SECURE
3. Seat Belts and Shoulder Harnesses  FASTENED AND SECURE
4. Wing Flaps  SET TO LANDING POSITION
5. SpeedBrake™ Switch  SET TO OFF/DOWN POSITION
6. Descent ESTABLISH MINIMUM DESCENT (Set airspeed to 87 KIAS, and use power
to establish minimum descent, ±200 feet/minute. See 8.2 below for landings without power.)
7. Approach In high winds and heavy swell conditions, approach into the wind. In light
winds and heavy swell conditions, approach parallel to the swell. If no swells exist,
approach into the wind.
8. Touchdown Alternatives
8.1. Touchdown (Engine power available) Maintain minimum descent attitude. Apply
power to slow or stop descent if necessary. When over a suitable touchdown area,
reduce power and slowly settle into the water in a nose up attitude near the stalling
speed.
8.2. Touchdown (No engine power available) Use an 80 to 85 KIAS approach speed
down to the flare-out point, and then glide momentarily to get a feel for the surface.
Allow the airplane to settle into the water in a nose up attitude near the stalling speed.
9. Evacuation of Airplane  Evacuate the airplane through the pilot or passenger doors. It may
be necessary to allow some cabin flooding to equalize pressure on the doors. If the pilot or
passenger doors are inoperative, use the crash ax/hatchet (located below the front seat on the
pilot's side) to break either window on the main cabin doors. For more information see the
Crash Ax discussion on page 3-36.
10. Flotation Devices  DEPLOY FLOTATION DEVICES
Over glassy smooth water, or at night without sufficient light, even
experienced pilots can misjudge altitude by 50 feet or more. Under such
conditions, carry enough power to maintain a nose up attitude at 10 to 20
percent above stalling speed until the airplane makes contact with the water.
