It is not a "queezy tummy" that would put me off, but a tired, old 1970's C152 which has been abused as a training aeroplane all of it's life.
I'm older that that, and I'm still airworthy...
A plane is either airworthy, or it is not. If it is, it can safely do whatever it was approved to do. If it is not airworthy, it should not be flown.
As long as those of us within our industry refer to older aircraft as less than entirely airworthy, we are doing ourselves a terrible dis-service. If we lack confidence in our aircraft, and the people who maintain them, how could we ever impart confidence in aviation safety to those around us? My 70's 150 is older than the 70's 152, and I looped, rolled and spun it last night. I crossed the desert of Texas, New Mexico, and Arizona three weeks ago in a Cessna which is 46 years old. What a delightful OLD bird!
