MANUFACTURE AND FITMENT OF FRONT COCKPIT CANOPY JETTISON GUARD

An Australian PW-6U experienced an uncommanded front canopy jettison in flight.  Investigation into the event suggested that the canopy jettison could be triggered by inadvertent contact by the front pilot’s / passenger’s foot.  Warwick Gliding Club developed and had approved a modification to prevent uncommanded jettison by fitting a guard below the canopy jettison mechanism. This Airworthiness Directive mandates a similar protective guard to be manufactured and fitted on a PW-6U aircraft.  The guard design is based on the guard developed for VH-WGQ S/N 78/05/01.
