3.3 -- ENGINE FAILURES
EXCESSIVE PROPELLER ROTATION SPEED
Indicates :
--
a propeller governor failure
In that case, the propeller overspeed limiter will limit initially the
rotation speed to 2100 RPM approximately.
--
or a propeller governor and overspeed limiter failure
In that case, only the torque limiter operates to limit the power.
However, the pilot intervention is necessary to maintain
Np
≤
2000 RPM. The propeller reducer is designed for a max. Np of
2200 RPM.
1 -- Reduce the power and the aircraft speed to avoid propeller rotation
speeds higher than 2000 RPM.
2 -- Land as soon as possible.
3 -- Do not perform a go--around.
A go--around would damage the engine reduction gearbox
The airplane repair is mandatory before any other flight.
