Thought I would throw in a story here.
Years ago I was instructing an aerobatic student in a C152 Aerobat. On completion of an aileron roll he said the controls were "a bit stiff" and "was this normal?", Taking ove, I found the controls locked in roll (at the neutral poition), but free in pitch.
I flew the aircraft back to the field using rudder and elevator, where it was discovered that the cotter pin on the end of the control column had snagged part of the radio wiring harness while at full left aileron and full forward pitch. This prevented the control wheel from turning to the right, and I was probably just lucky that there was enough play in the harness for the wheel to reach neutral, and not be snagged at full left roll. (Or unlucky that there was enough play in the harness to catch the pin in the first place, depending on how you view life
)
A "four corners check" would have had a greater chance of catching the problem on the ground than a "forward back, left/right" check - which perhaps follows J.T.'s comment above about what you should be worried about.
As I said, I used to teach a four corners check, but have no idea whether the student did that on the ground or not now (it
was quite a while ago.)
