Time is money in maintenance business. There is always a pressure to shorten maintenance slots to achieve better utilization of the fleet. Engine borescope inspection is a typical maintenance event, where a certain cooling time is required before starting the inspection. Engine cranking may be done to minimize cooling time but there are some down lights: it will require licensed personnel to operate the engine. Also, long cranking periods will cause extreme stress for the engine’s air starter. FCS Avionics is a Finnish company that provides jet engine cooling solutions for MROs and airlines. We’re proud to present AFC-22, a jet engine cooling system. Please visit our website and see the video for more information.
