Trend Group has signed a teaming agreement with National Flight Services of Toledo, Ohio, to provide trend monitoring and analysis service for each overhaul and hot-section inspection it performs. Trend Group monitors and analyzes data routinely collected during the cruise phase of flight. It then alerts the operator of subtle changes in the engine’s performance, enabling the operator to correct minor problems before they develop into major ones. The proactive approach can lower operating costs, enhance safety and improve maintenance planning.
