Description
7.9.3 PROPELLER
A mt-Propeller MTV-12-B/180-17 type or MTV-12-B/180-17f type, hydraulically-regulated
3-bladed constant speed propeller is installed. It has wood-composite blades with fiber-
reinforced plastic coating and stainless steel edge cladding; in the region of the propeller
hub the leading edge is coated with adhesive PU foil. These blades combine the lowest
weight whilst minimizing the chance of vibration.
Operation on the ground at high RPM should be avoided as
far as possible, as the blades could suffer stone damage. For
this reason a suitable site for engine runs (magneto and
propeller checks) should be selected, where there are no
loose stones or similar items.
Never move the propeller by hand while the ignition is
switched ON, as it may result in serious personal injury.
Never try to start the engine by hand.
