Hi Neville I had a similar problem soon after coming to Australia. John Viney also experienced this. In my case it was due to the trailing edge of the brake panel jamming in the top surface of the wing and was cured by filing back the trailing edge of the panel - just a very small amount.
Your problem might be different as, in my case, as soon as the panel was lifted a few mm, it was then easy to lift it the rest of the way Michael From: neville swan Sent: Tuesday, November 02, 2010 3:36 AM To: [email protected] Subject: [DOG mailing list] Re:Sticking airbrake Hi All. Has anyone come across the problem of an airbrake that wont extend? No problem until last weekend when, during the DI, I found it impossible to extend the brakes with the cockpit handle, using a fairly hefty pulling force. I had to slide a feeler gauge under the rear edge brfore I could open the starboard brake panel (the port one is not a problem). I could not see anything amiss and added a small rubber 'buffer' to lift the rear edge a couple of mm., but it did not make any difference. Almost feels as if the torque tube is 'over centre'. Any ideas? Incidently, my brake panels have a small spring at the inboard ends, presumeably to help keep them closed. One panel has had an extra spring added about 3/4 out (not the sticking one). What is the norm? Neville.
