DSS Course DC30 (8 Hrs)

Level 1 Helicopter Vibration Maintenance - Rotor System Track & Balance

Description: This course introduces vibration theory, balancing, and measurement of vibration as applied to rotary-wing aircraft. The classroom session emphasizes proper use of the MicroVib II Aircraft Analyzer for both propeller balancing and vibration analysis. The flight line session allows the equipment user to have "hands-on" experience installing and using the MicroVib II Aircraft Analyzer on actual aircraft.
