An automated helicopter maintenance monitoring system (20), which is comprised of a flight data recorder subsystem (22) and a maintenance computer subsystem (24), collects data from a plurality of sensors in order to facilitate helicopter maintenance. The system (20) processes vibration data, rotor track data, rotor phase data, and flight sensor data to determine when a helicopter fault has occurred or will occur. Additionally, the system (20) can prompt a pilot/maintainer to fly the helicopter through specific operational states in order to aid in the maintenance process.
