EVEKTOR-AEROTECHNIK AS SPORTSTAR PLUS
During initial takeoff climb after performing a touch-and-go landing, the airplane's canopy opened to the forward position. The pilot landed the aircraft on the remaining runway; however, the airplane departed the end of the runway, struck a landing threshold light, and came to rest upright. Postaccident examination of the airplane revealed that the canopy latch spring had failed. In addition, the spring mounting plate used to hold the spring in position did not have a relief area machined into the plate that was required for the correct operation of the spring. The spring and assembly had been installed approximately 32 hours prior to the accident.
