Aircraft Monitoring and Preventative Maintenance

    Airframe life can be significantly reduced due to structural fatigue. The variety of flight profiles an aircraft may undertake makes it difficult to base airframe life on flying hours alone. It is therefore vital to monitor stress in both magnitude and frequency of occurrence.

    Preventative maintenance schedules by aircraft fleet operators and component suppliers (e.g. propulsion systems) often rely on real time monitoring of parameters such as frequency of stresses, accelerations and vibration issues to determine airframe/component integrity and automatically schedule checks or appropriate remedial action.

    Sensor data is therefore critical for keeping the aircraft flight worthy and the financial value in the preventative maintenance schedule is maintained keeping the aircraft in an optimal, safe, flight ready condition.

    Accelerometers and Gyros are key tools to provide significant data monitoring capabilities and inputs into any preventative maintenance and condition based monitoring programme.
