The offer: The L-39C were stored in theory according to military procedures including full tanks and engine test runs every 6 months. In fact, in most cases the storage was paper fiction. Thus a careful study of logbooks and detailed inside information are crucial in our selection of the aircraft. We offer 1974 to 1986 aircraft with airframe total hours from 1000 and with 400 to nearly 1000 hours TBOs on the engines. A full-scale mandatory de-conservation and extended maintenance at a certified facility is performed prior to delivery, including structure magnetic control, magnesium parts replacement, new fuel tanks, ejection seats overhaul and much more, to provide a fully operational and weight-optimized aircraft.
