So i read and understand all the insight to these Qs and As. Giving that after reading thru the FI and GS we have a plane that flaps locked up in flight. After trouble shooting the A brakes are rigged good, and the signal coming from them is good at the cannon plug. But with power and hyd pres. The manual switch moves with some force but will not reset. The flaps move manually but the hyd brake is locked and they will not move with hyd. The FI does not specify this problem and i am only 3 yrs into this plane. Im thinking bad brake valve. Any thoughts?
