MAINTENANCE MANUAL
2.4.4 PRE‐ROTATION SYSTEM
The function of the pre‐rotation system is to provide to the rotor unit the initial acceleration necessary for take‐off.
The pre‐rotation control line stretches all along the gyroplane's structure, starting at the lever placed before the
control stick and reaching the transmission unit through a sheathed steel cable. When the pilot operates the
control lever, the two belts located close to the propeller are tensioned through the tightener, which is part of the
transmission unit to which the control cable is connected.
Once the belts are tightened, the propeller's motion is geared down and transmitted through the transmission and
through a flexible steel shaft to the Bendix gear. This gear, once started, engages the rotor head's notched gear to
which the blades are anchored.
The tension exerted on the belts vanishes when the pre‐rotation lever is released, thus stopping the transmission,
flexible shaft and gear. This same gear moves back and disengages the crown, thus freeing the rotor so that it can
rotate.
2.5 SUSPENSION, WHEELS AND BRAKES
The suspension of the gyroplane is realized through a leaf spring in composite material.
The manufacturer does not authorize any repair of this unit. Any crack or damage to the suspension has to be
referred to Magni Gyro.
Minor surface abrasions and scratches can be repaired using standard composite repair techniques.
If any of the wheel or brake components are found to be damaged, then replacement with new or repaired parts is
the only option.
Magni Gyro's policy is to recommend replacement of any worn or damaged parts rather than repair. In the long
run the cost of a new wheel axle will probably be less than trying to repair a bent or damaged one and ensures
greater flight safety.
If the front fork is found to be bent or distorted, then this unit is to be replaced. Unauthorized repair can lead to a
unit that is much weaker as the original one and could fail in service (for inspection procedures see the specific
paragraph).
2.6 POWER PLANT
Any repair or overhaul of the engine must be carried out by personnel trained and qualified by the ROTAX
Company, in strict accordance with the latest amendment state copy of the maintenance and operator's manuals
applicable to the engine.
Details of any work carried out must be entered in the relevant engine logbook.
This logbook must be kept up to date and accurate and be available for presentation when work is carried out and
at permit to fly renewal.
For more information, see the relevant section.
