2.Brakes . . . . . . . . . . . . . . . . . . . . . . . . . . . . . as required
NOTE
If considered necessary, the engine must be shut down.
Otherwise the cause of the problem must be established in order to re-establish engine performance.
CAUTION
If the oil pressure is in the red range, the engine must be shut down immediately.
WARNING
If the problem cannot be cleared, the airplane must not be flown.

3.3.2 ENGINE PROBLEMS DURING TAKE-OFF
(a) Take-Off Can Still Be Aborted (Sufficient Runway Length Available)
Land Straight Ahead:
1. POWER lever . . . . . . . . . . . . . . . . . . . . . . . . IDLE
On the Ground:
2. Brakes . . . . . . . . . . . . . . . . . . . . . . . . . . . . . as required
WARNING
If sufficient time is remaining, the risk of fire in the event of a collision can be reduced as follows:
- |
Fuel valve . . . . . . . . . . . . . . . . . . |
OFF |
- |
ENGINE MASTER . . . . . . . . . . . |
OFF |
- |
ELECTRIC MASTER . . . . . . . . . . |

Procedures
(b) Take-Off Can No Longer Be Aborted
1. Airspeed . . . . . . . . . . . . . . . . . . . . . . . . . . . . immediate pitch down to avoid airspeed reduction
WARNING
If, in the event of an engine problem occurring during take-off, the take-off can no longer be aborted and a safe height has not been reached, then a straight-ahead emergency landing should be considered. Do not attempt to turn back to the airfield. Turning back can be fatal.
If Time Allows:
2. POWER lever . . . . . . . . . . . . . . . . . . . . . . . . check MAX 3. Fuel pumps . . . . . . . . . . . . . . . . . . . . . . . . . check ON 5. VOTER switch . . . . . . . . . . . . . . . . . . . . . . . check AUTO
WARNING
If the problem does not clear itself immediately, and the engine is no longer producing sufficient power, then an emergency landing must be carried out in accordance with
3.7.1 - EMERGENCY LANDING WITH ENGINE OFF.

3.3.3 ENGINE TROUBLESHOOTING IN FLIGHT
WARNING
Control over the flight attitude has priority over attempts to solve the current problem ("first fly the airplane").

2. POWER lever . . . . . . . . . . . . . . . . . . . . . . . . MAX
NOTE
If the loss of power was due to unintentional setting of the
POWER lever, you may adjust the friction lock and continue your flight.

WARNING |
% |
Do not increase the POWER lever past the propeller speed |
% |
of 1975 RPM or the setting determined in step 6. An increase |

of engine power beyond this setting leads into another power |
% |
loss. |

NOTE |
% |
With this power setting the engine can provide up to 65 % |

load at the maximum propeller speed of 1975 RPM. |
%7. Land at the next suitable airfield.
%Otherwise:
Depending on the situation the following attempts can be made to restore normal engine operation:
3.Circuit breakers . . . . . . . . . . . . . . . . . . . . . . check / reset if necessary
If normal engine operation is restored continue flight and land as soon as possible.
Otherwise:
4. VOTER switch . . . . . . . . . . . . . . . . . . . . . . . |
swap between ECU A and B |
If either ECU A or B setting restores normal engine operation then maintain ECU setting and land as soon as possible.
