Uplinker and Bergerie1
Agreed about the criticalilty of checking controls post maintenance on an aircraft where the controls are not visible from the pilots seats. I've only flown small stuff, where you could see the control surfaces, but would check full and free movement, in the correct sense, before taxi every flight and give the stick a good stir just before departure. Looking at the stakes involved, it seemed a very wise investment of a few seconds.
