Engine OEMs occasionally issue revised life limits for engine critical components based on service events or a revised life analysis. If the revised life limit is significantly lower than the previous limit, a significant number of installed parts may be affected and fleet availability may be impacted. QinetiQ Novare can assist fleet managers in working with their engine OEM and airworthiness regulatory body to implement risk management programs to safely overcome component life reductions that have the potential to significantly impact fleet availability.
