7.1.2 Fuselage and Cockpit
Test of canopy emergency jettisoning system: In flight configuration, carry out jettisoning procedure in
accordance with the instructions in the Flight Manual. The canopy is to be checked smoothly by two
assistants standing in front of the aircraft (to the left and to the right).
Up to S/N 19 the reinstallation of the canopy is to be performed by means of a special tool to facilitate the
compression of the gas spring in the canopy hinge.
For later S/N the installation procedure is the following: compress the gas spring by hand and jam it
underneath the rim of the hole. Fit the canopy and initialize the spring by pushing it towards the hole by
means of a pin through the little hole on the right side of the spring housing.
Warning: If the gas spring is not initialized as described before, the canopy will not open when jettisoning is
released during flight.
