with 8,306 hours on an airframe, what is the life limit to a) stop flying aerobatics, and b) stop flying normal category?
There is no life limit for any Cessna 150 or 152 that I am aware of or heard of.
When I say any Cessna 150 or 152 that includes the Aerobats and being able to do aerobatics.
Maybe someone with more knowledge than I have will speak up.
