i have read some drivel in my time , but remind me not to be around when Mario is flying his Cessna . In the first place, i know of no instance where an elevator ofraileron cable has snapped, and I get the Air Accident investigation board bulletins every month, and have done for over 40 years , and in the second place, the rudder will provide secondary roll control ( up to a point ) with an aileron failure, as will the elevator trimmer with an elevator control failure . Was this posted a week or two too early ???
