Drivetrain components are a critical safety system for rotary winged aircraft. Excessive vibration has caused catastrophic component failure resulting in destruction of aircraft and loss of life. Helicopter operators recorded data detailing vibration related issues concerning the aircraft; this information includes Precautionary Landings, Forced Landings, accidents and incidents related to excessive drivetrain vibrations. CDB will mitigate these types of risks and hazards while increasing crew confidence in the machine.

CDB is a “Preventive Maintenance Process” it keeps the vibration deterioration rate low and moves component lifetime closer to TBO in order to eliminate potential risks of catastrophic component failure.

By reducing vibration in the drivetrain, and keeping it low through preventive maintenance, the aircraft can achieve and maintain a minimum vibration profile over its life, therefore increase aircraft safety.

CDB application is a very useful tool for identifying and troubleshooting various material issues beyond the drivetrain. This can result in important material deficiencies being identified and resolved prior to a casualty.
