AAIB investigation to Sling 4, G-LDSA

Canopy door detached in flight, Near Hailsham, East Sussex, 27 July 2017.


The right canopy door detached in flight. Subsequent inspection of the aircraft, and in particular the canopy latch pins, by the LAA indicates that the canopy locking lever had not been in the fully closed position, which allowed the canopy to open and then detach. The canopy, incorporating the locking lever and mechanism, was not recovered. There have been no other reported incidents of canopy loss for this aircraft type. The LAA is to publish a safety article reminding pilots to check that canopies are fully locked prior to flight.
