Gfa 170an Issue 4


Applicable to the Puchacz canopy latch mechanism. Canopy opening in flight due to poorly rigged and/or worn latch mechanism. There have been reported incidents in Australia and more reported world wide of uncommanded canopy openings in flight. One occurrence occurred whilst on aerotow in turbulent conditions, one reported during the recovery from a spin and another whilst performing a left hand side slip. Only one of the above Australian occurrences resulted in the loss of the canopy. A partially locked, worn or incorrectly rigged latch system will increase the chance of the canopy opening in flight under some flight conditions.
