Jet Support Services has launched an educational video series as part of a continuing education program offered in conjunction with the National Aircraft Finance Association. Targeting aircraft appraisers and the aircraft finance market, it examines critical maintenance issues for both engines and airframes and how they affect the valuation of business jets. The first segment covers hard time and on-condition engines; the second reviews on-condition task-oriented engines; the third is on corrosion of turbine engines; the fourth looks at maintenance scheduling and operating cost; and the final segment covers airframe corrosion.
