Our flight school is in search of an undamaged left wing for a Blanik L23.. we discovered damage to the wing spar on inspection and are having a very hard time finding replacement in a reasonable time frame (6 months). Any help or leads would be appreciated. TIA

Miami Gliders bought a L-23 with a damaged right wing from Cesar Creek. You may be in luck! Give them a call.
