Diamond Da40 Emergency Procedures

Front 1

Engine problems on the ground

Back 1

Throttle . . . Idle

Engine . . . . switch off if considered necessary, otherwise establish the cause of the problem and re-establish engine performance


CAUTION: If the oil pressure is below the green sector, the engine must be switched off immediately

WARNING: If the problem cannot be cleared, the airplane must not be flown

Front 5

You have a loss of oil pressure. What should you check?

Back 5

Check the oil pressure warning light and pressure indicator

Check the oil temperature

Front 6

Loss of oil
Oil temperature is normal (oil pressure warning light does not illuminate or flash)

Back 6

Monitor the oil pressure warning light. It is probable that the oil pressure indication is defective.

You should monitor the oil temp. and CHT.

Front 7

Oil pressure indication drops below green and:

1. CHT is rising , and or
2. Oil pressure warning light illuminates

Back 7

1. Reduce engine power to the minimum req.
2. Land ASAP
3. Prepare for engine failure and emergency landing

Front 8

Oil pressure tending to 0 combined with vibration, loss of oil, unusual metallic noise and smoke

Back 8

A mechanical failure in the engine is apparent

1. Shut off engine immediately
2. Carry out emergency landing

Front 9

High oil pressure. What do you check?

Back 9

Check your oil temperature

Front 10

High oil pressure
Normal oil temperature

Back 10

The fault probably lies in the oil pressure indication which should be ignored ( The airplane should be serviced)

Front 11

High oil temperature

Back 11

1. Check CHT and EGT.
If neither of these is high, it is probable that the fault lies in the oil temperature indication. The airplane should be serviced. A stable oil temperature indication of 26°F or 317°F suggests a failure of the oil temperature sensor.

If CHT or EGT is also high, check oil pressure.

If the oil pressure is low, proceed as in 3.2.3 (b)- Loss of oil pressure.

If the oil pressure is in the green sector, check the mixture setting, enrich mixture if necessary and or reduce power. If this produces no improvement, land at the nearest appropriate airfield.

Front 12

CHT is in the yellow sector or above

Back 12

1. Check mixture setting, enrich mixture if necessary

2. Check oil temperature

If the oil temperature is also high, check oil pressure. If the oil pressure is low, proceed as in 3.2.3 (b) Loss of oil pressure.

If the oil pressure is in the green sector

Reduce power. if this produces no improvement, land at the nearest appropriate airfield. Be prepared for possible emergency landing

Front 13

High RPM- RPM moves on its own into the yellow sector, or is in the red sector

Back 13

Check friction adjuster for throttle quadrant.

Check oil pressure: Following a loss of oil or oil pressure, the propeller governor sets a high RPM. In this case the RPM should be regulated using the throttle. Proceed as in 3.2.3 (b) Loss of oil pressure.

If oil pressure is normal, pull RPM lever back and listen for an associated drop in RPM

- If the indication does not change in spite of an audible drop in RPM, it is probable that the RPM indication is defective which should be ignored (the plane should be serviced)

- If there is no audible drop in RPM, it is probable that the governor system is defective, in this case the RPM should be regulated using the throttle.

Front 14

Loss of RPM

Back 14

1. Fuel pump . . . . . . . . . . . . . . . . . . . . . Check On
2. Fuel tank selector . . . . . . . . . . . . . . . . Check
3. Friction adjuster for throttle quadrant . . Check sufficiently tight
4. RPM lever . . . . . . . . . . . . . . . . . . . . . Set on HIGH RPM

- Listen for rise in RPM
- If there is no audible rise in RPM, it is probable that the governor system is defective. In this case the RPM can be regulated within certain limits using the throttle
@ Land at the nearest airport
@ Prepare for possible emergency landing

- If the indication does not change in spite of an audible rise in RPM, it is probable that the RPM indication is defective, which should thus be ignored (the plane should be serviced)

Front 15

High fuel flow (in the red)

Back 15

1. Check the fuel pressure
- If the fuel pressure is low, there is possibly a leak (between the injection system and the injectors). Land at the nearest available airfield
- If the fuel pressure is in the green there is no leak; the likely cause is a defective fuel flow indication, which should thus be ignored (the plane should be serviced)

2. Check fuel quantity. A rapid reduction in fuel quantity confirms a high fuel flow

Front 16

Restarting the engine with windmilling propeller

Back 16

Note: Restarting the engine is possible at all airspeeds above 70 KIAS up to Vne and up to the maximum demonstrated operating altitude.

Note: As long as an airspeed of at least 65 KIAS is maintained, and there is no major engine failure, the propeller will continue to windmill.

1. Airspeed . . . . . . . . . . . . . . . . . . 80 KIAS
2. Fuel tank selector . . . . . . . . . . . Fullest tank
3. Ignition switch . . . . . . . . . . . . . check BOTH
4. Mixture . . . . . . . . . . . . . . . . . . check appropriate position
5. Fuel pump . . . . . . . . . . . . . . . . . check ON
6. Alternate air . . . . . . . . . . . . . . . OPEN

- if engine does not start:
7. Mixture . . . . . . . . . . . . . . . . . . . . LEAN
8. Mixture control lever . . . . . . . . . . . Push forward slowly until engine starts

NOTE: If it is not possible to start the engine
- adopt glide configuration as in 3.4 - GLIDING
- carry out emergency landing as in 3.5.1 - Emergency landing with engine off

Front 17

Defective mixture control cable

Back 17

(a) Flight and landing:
1. Maintain altitude to the nearest airfield
2. During descent, test the reaction of the engine to a higher power setting. A lean mixture can lead to engine roughness and a loss of power. The landing approach must be planned according.

WARNING: Go-around may become impossible with the remaining power.

(b) Engine shut-down:
1. Parking brake . . . . . . . . . . . . . . . . . . . . . set
2. Engine instruments . . . . . . . . . . . . . . . . . check
3. Avionics master switch . . . . . . . . . . . . . . . OFF
4. All electrical equipment . . . . . . . . . . . . . . OFF

NOTE: By increasing the airspeed above approx. 130 KIAS, the propeller will begin to rotate and the engine can thus be started. For this, the ignition switch should be set at BOTH (see 3.2.4 Restarting the engine /w windmilling propeller) An altitude loss of at least 1,000 ft. (300 meters) must be allowed for:

if it is not possible to start the engine:
-adopt glide configuratio

Front 25

Electrical fire /w smoke in flight

Back 25

1. Emergency switch . . . . . . . . . . . . . ON if installed
2. Master switch (BAT) . . . . . . . . . . . OFF
3. Cabin heat . . . . . . . . . . . . . . . . . . OFF
4. Emergency window(s) . . . . . . . . . . open if req.
5. Land at an appropriate airfield ASAP

Caution: Switching OFF the master switch (BAT) will lead to total failure of all electronic and electric equipment, Also affected from this are - if installed - the attitude gyro (artificial horizon) and the directional gyro. However, by switching the emergency switch ON (only installed on the IFR model), the emergency battery will supply power to the attitude gyro and the flood light.

In case of extreme smoke development, the front canopy may be unlatched during flight. This allows it to partially open, in order to improve ventilation. The canopy will remain open in this position. Flight characteristics will not be affected significantly.
