Slingsby T67C Firefly, G-RAFG
Whilst climbing prior to demonstrating an aerobatic manoeuvre, the cockpit canopy suddenly opened shattering the perspex. The frame remained attached to the aircraft which made a safe landing without further incident. Non-incorporation of a modification to improve ease of checking for correct engagement of the latch mechanism or maladjustment of the mechanism are considered as possible factors in this incident.
