Aero L-39C Albatros, G-OALB

Summary:

The pilot shut both canopies before takeoff but the canopy “unlocked” light remained illuminated. Visual inspection confirmed that, the external locking handles appeared to be stowed correctly and the pilot believed that the micro switch that operated the “unlocked” light was incorrectly adjusted. During the takeoff, the rear canopy detached and came to rest beside the runway. The aircraft returned to the airfield safely, having sustained no further damage. An investigation revealed that the locking handle can be stowed without first locking the canopy, and that correct operation of the lever is the only means of ensuring that the canopy is secure.
