3.9.2. Oil feed malfunction
If the oil pressure is low, look at the oil temperature
If the oil temperature rises (into the red), reduce engine power to setting to the minimum necessary
and carry out precautionary landing. Prepare to make a forced landing.
3.9.3. Low voltage (red lamp)
Switch off all non-essential electrical equipment and fly to the nearest airfield and land.
Remark: The engine has electrical fuel pumps only. With a failed generator the engines fuel supply
depends on the battery. The remaining flight time with running engine depends on the charge state
of the battery. With a battery in good conditions and switched off consumers expect a remaining
flight time of 30 minutes.
3.9.4. Sudden drop of boost pressure and speed
- Loud noise or bang:
A fracture of the turbo is likely.
Look for landing possibility. Flight with reduced performance may be possible.
Monitor oil
pressure
.
- The orange caution lamp of TCU (turbo control unit) is blinking.
Limited flying operation as possibly wastegate does not close any more
NOTE:
A minimum performance of approx. 66 kW remains available.
Any exceeding of the max. admissible operating limits and/or blinking of orange caution lamp must
be recorded by the pilot in the logbook, stating the duration, exact time and extent of exceeding.
3.9.5. Sudden rise of boost pressure and speed
- Orange caution lamp of TCU is blinking:
Immediately reduce engine speed until boost pressure and speed are within operation limits.
Limited flying operation as wastegate may be fully closed and control of the boost pressure is only
possible via throttle lever.
- Bowden cable(s) for actuation of throttle valve(s) broken:
Due to spring pressure the throttle valve(s) will be fully open –
full throttle
!
Limited flying operation as wastegate may be fully closed and control of the boost pressure is only
possible via throttle lever.
Any exceeding of the max. admissible engine speed or boost pressure has to be recorded by the
pilot in the logbook, stating the duration, exact time and extent of exceeding.
