Has anyone heard about this?
According to that NTSB link at the bottom, It sure would suck to be in an actual spin and not have rudder control.
The FAA is proposing to take airworthiness action on Cessna 150/152 airplanes following a March 21 NTSB recommendation regarding two rudder-related accidents. The proposed AD would require replacing the rudder stop, rudder stop bumper, and attachment hardware with a new rudder stop modification kit. It would also require replacing the safety wire with jamnuts. In the two accidents, the FAA said the rudders were found in the over-travel position with the stop plate hooked over the stop bolt heads. Owners would need to comply within the next 100 hours time-in-service or 12 months after the effective date of the AD, whichever occurs first. The estimated cost is $380 per airplane, and it would affect 18,670 airplanes in the U.S. registry. The comment deadline is June 15.NTSB
