Main Rotor

The rotating assembly which supports the main rotor blades including blade folding system. Includesthe swashplate if it is an integral part of the mast head assembly. Also includes the head mechanism ontilt rotor aircraft. Typical parts are sleeve, spindle, damper, fairing. Does not include the controllingaspects in JASC code 6710.

Hydraulic Power

For reports of hydraulic pressure and quantity indicating system parts other than the indicator or sensoror for parts common to both pressure and quantity systems.

Main Rotor

The vertical shaft which supports the main rotor head. Typical parts are shaft, bearing, guide, mast,seal, swashplate, etc.

Hydraulic Power

The instrument and associated low pressure warning system that registers system pressure. Typicalparts are indicator, warn lamp, bulb, etc.

Main Rotor

The system used to indicate the operation or activation of the main rotor. Includes lights, gauges,switches, wiring, etc.

Hydraulic Power

The components that sense system pressure and transmit a signal to the cockpit indicator or lowpressure warning lamp. Typical parts are transmitter, pressure switch, sensor, etc.

Main Rotor

For reports indicating a problem with wiring specific to the Main Rotor System.

Hydraulic Power

The instrument and associated low level warning system which registers reservoir fluid quantity. Typicalparts are indicator, lamp, bulb, sight gage, etc.

Main Rotor Drive

For general reports of main rotor drive system with insufficient information to file in a more specific JASCsub-system code. Excessive use of this code should be avoided if possible.

Hydraulic Power

The components that sense the fluid level and low level warning and transmit a signal to the quantityindicator. Typical parts are transmitter, sensor, float switch, etc.
