Course DC50 (8 Hrs) - FAA Course: C-IND-IM-120316-K-006-018

Helicopter Vibration Analysis

Description: This course introduces vibration theory and vibration analysis as applied to fixed-wing aircraft. The classroom session emphasizes vibration theory and methods available for use in performing vibration analysis of rotary-wing aircraft. 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.
