Fully enclosed canopy Semi-open canopy with sun-screen
If an aircraft is purchased with two different canopies (e.g. fully enclosed for winter use,
semi-open for summer use) it is permissible for the pilot to inter-change the canopies,
although each such action must be recorded in the aircraft log-book together with the
pilots name and CAA authorisation number. The fitment must be checked by a second
pilot or A3-7 Authorised Person who must also annotate the aircraft log book with their
name and authorisation number. NB: Canopies are hand-fitted to individual aircraft and
should not be changed between aircraft.
The canopy is hinged on the LH (port) side of the aircraft and locked by a single detented
lever on the RH side of the aircraft. When open, the canopy is restrained by a webbing
strap on the rear LH side. When closing, the canopy is guided on to the enclosure by
means of two tapered spigots on the enclosure and mating holes on the canopy
underside. The webbing strap is guided into the cockpit by a bungee arrangement.
Canopy location spigots and mating holes on the RH side
With fully-enclosed canopies the locking lever passes through the canopy wall so that it
may be operated from inside and outside the aircraft. With the semi-open design a lever
is fitted optionally inside the cockpit only as it may be reached from outside through the
open aperture.
