Many thanks for your offer, we will battle away his weekend and let you know how it goes, i think your Canberra at East Kirkby is an Ex Upwood bird too:D

We have a door at East Kirkby that we took off the nose, you are welcome to come and have a look to see how it is attached/detached from the nose section.

A big thankyou for all of your advise, i will try the hinge release – i have a nasty feeling its seized too though 😡
Ahhh, I had misunderstood slightly, thought the door was off with the pins stuck down having already used the emergency release :rolleyes:…anyway, whilst the 4 and 1 quarter turn handle above the door should release it (if not siezed too), it is possible for the door seal to have semi-permanently attached itself to the door and it can put up one hell of a fight. You may need to prize it all the way around the door frame, then give it the necessary swift kick towards the top. Make sure you have someone ready to catch it outside, as they are heavy and the outer lip can bend if it hits the deck when you kick it.
I can sort diagrams if they would be of help 😀

The sockets in the fuselage that the door locking pins fit into are not a tight fit. They are designed to allow the door to rotate outward and fall away after the hinges at the top have been released.
So if the bottom hinge pins are corroded in the door this should not affect door removal after the top hinges have been released. That is of course assuming that the hinge release mechanism is not corroded also! Of course you do need to have access to the cockpit to operate this release mechanism.
No doubt somebody on this forum will be able to post a schematic from the manual to show this works:)

But IF the locking pins are seized/corroded in the lock position surely the hatch will stay in place, even if you do fiddle with the hinges?
The emergency door jettison handle withdraws the top door securing claws releasing the door from its retaining hinge at the top, it does not release the bottom pins which stay in position, the door then falls outwards rotating from top to bottom it will need a push and is heavy!!

The memory of CS is correct for the T.17 as well.
Entrance door jettison gear contained with the frame of the door hole at the upper side.
Rotate crank clockwise to withdraw hinge pins.
Prescribed method of removing door for servicing while on the ground.

Is there not a means of manually disconnecting the hinges for emergency jettison ?
I seem to remember that there was a winding handle on the inside of the fuselage to rotate the hinges to allow the door to be pushed out without using the normal handle. Four turns seems to ring a bell!
The only way out for the ground eng on a jolly in a PR7 in an emergency.

door grief
Sadly (though not for me) being on the last Canberra Squadron, if we had door troubles we just changed the door as opposed to the lock, so I never had the need to dismantle one! Some tickling with a hammer and wooden block on the pins should relieve them with the rods disconnected (you have that luxury unlike many!) then after that, stick the rods back on, operate the mechanism with a handle and you should see some progress.

Not without causing damage when the door is shut. You need to drive them pins out. Having the door lock fitted or not dosen’t make any difference as you can disconnect the operating rods.

Cheers Timbo ,i’ve disconnected the pins from the links and them darn pins still dont wanna shift ….is there any way of taking the hinges off?
By: pagen01 - 30th August 2008 at 18:52
I know someone else who has just been through this!
They had to enter the cockpit via the Nav roof hatch, but it sounds like you can get in anyway. The two main door locking pins had corroded and seized shut in the fusalage receiver holes, I believe penetrating oil, screw drivers and hammers were used!
I can try and ask for more detail if required.

borrowage
Hi Matt
I can lend you a door handle to help as the gearing will prohibit you from moving the pins with anything but a handle of any kind I should think , but you’ll want to give the pins a darn good soak in releasing fluid first – Canberra door handles bend easily (Lesson learned the hard way :rolleyes:)
Lemme know if you wanna give this a shot
