Only happened to me once during a check ride with an unfamiliar instructor/examiner. He was about 2 hours late for the check and we were losing the light so we jumped in and I taxied out..........the rudder pedals were as heavy as hell and pulling to one side. As we taxied to the (grass) runway, I politely asked him to get his ruddy feet off the pedals and he said "not guilty"
.....After I had changed the flat tyre with the help of a couple of the club instructors, we set off again with me trying to convince the examiner that I really had checked the tyres during the preflight but it must of got a punture during the 2 hour wait for him to turn up....
Anyway check flight passed.
