Canberra PR.9 – Canopy Operation

AP101B-0409-1E

Using this AP as a basis,the relevant Illustrated Parts Catalogue for your canopy system would be AP 101B-0409-3(?) unsure of suffix but prob between ‘c’ and ‘ f ‘,but it will be in chapter 15(fuselage/transparences) normally

cheers baz

Sorry,

None given in the AP only the following description:

The hood operating spring box mounted on the rear fairing contains two springs, an inner and an outer, which are fitted between two retaining pieces over an inner tube assembly, the whole being housed in a light alloy barrel.

Never removed the fairing on 175 to expose the beast so no piccys.

Many thanks for prompt response Ross, do you happen to have a part number for the Spring Box?

AP101B-0409-1E

The hood, which may be jettisoned in an emergency, is hinged to the rear fairing structure and is opened to provide normal entry and exit for the pilot. In the closed position the hood is secured by four locking pins, two on each side of the aperture, which engage with holes in shoot bolt recievers fitted to the side members. When the pins have been withdrawn, the hood is lifted and retained in the open position by a spring box mounted in the rear fairing.

The main component to raise and lower the canopy is the pilots arm.

Ross
