Course DC30 (8 Hrs) - FAA Course: C-IND-IM-120316-K-006-016

Level 1 - Helicopter Vibration Maintenance

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 rotor track and balance, 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.

Who Should Attend: Recommended for aircraft maintenance technicians and engineering personnel who have little or no previous experience in vibration theory and/or balancing.
