2. Canopy Description and Operation
Figures 1 and 2 show the canopy installation.
A. Canopy Description
The canopy is a CFRP molding with inner and outer frames. The frames bond together with
thickened resin. Each part of the frame has layers of carbon cloth and one layer of glass cloth.
Areas of high stress have extra layers of carbon cloth. Mounting bushes for the handle and locking
bolts bond to the inside of the frame with thickened resin.
The canopy has a large one-piece acrylic glass window. A special flexible adhesive bonds the
window to the canopy frame. A flexible filler seals the small gap between the edge of the window
and the frame.
The window has a an emergency window on the left side. Some airplanes also have an emergency
window on the right side. You can open the emergency windows in flight. Refer to Chapter 56 for
data about the window.
B. Canopy Hinge Frame
The canopy attaches to a tubular steel frame at the front (the hinge frame). The frame attaches to
two hinges on the rear face of the firewall. A gas spring strut attaches to the hinge frame and the
bottom of the firewall. The canopy moves up and forward to open. The gas spring strut holds the
canopy open. A door unlocked warning light (DOOR or DOORS) on the annunciator panel operates
% when the canopy is unlocked (not all S/N).
C. Canopy Attachment
(1) S/N's through 40.051
Refer to Figure 1. The canopy has two tubular brackets on the front edge of the canopy frame.
Two bolts attach each bracket to the canopy frame. One bolt attaches each bracket to the hinge
frame. You can remove the canopy by removing these two bolts.
(2) S/N's 40.052 and subsequent
Refer to Figure 2. The canopy has two attachment plates on the front edge of the canopy hinge
frame. Two bolts attach each plate to the canopy frame. You can remove the canopy by
removing these four bolts.

Figure 3 shows the canopy locking mechanism.
A handle on the left of the canopy operates two locking bolts. The handle has a spring assisted overcenter
lock which holds the handle in the closed position. The locking bolts are at the bottom rear
corners of the canopy.
The handle has two parts. The inner handle is black and has a double lever. The outer handle is red
and attaches to the inner handle with two roll pins. A connecting rod attaches to the rear of the double
lever. The other end of the connecting rod attaches to the inside of the left locking bolt.
A teleflex cable attaches to the front of the double lever. The teleflex cable goes inside the front of the
canopy frame to the right locking bolt. If you pull the canopy handle away from the canopy frame, these
things happen:
) The double lever turns to pull the connecting rod and the teleflex cable.
) The connecting rod pulls the left locking bolt forward.
) The teleflex cable pulls the right locking bolt forward. The forward movement of the locking bolt
% operates the door unlocked warning micro-switch (not all S/N) in the right side fuselage shell.
The canopy can be pushed up and forward to open.
With the canopy fully closed, push the canopy handle towards the canopy frame. This engages the
locking bolts in the fuselage holes. The spring assisted over-center lock holds the handle in the closed
% position. The right locking bolt operates the micro-switch (not all S/N) for the door unlocked warning
light (DOOR or DOORS). When the handle is flush with the canopy frame, the canopy is locked. Push
up on the rear of the canopy frame to make sure that it is locked.
