Not that I'm aware of. And, just so it gets said, there is no wing failure issue on the early CH 601 aircraft (produced and flown for many years without incident). The problem is/was with a different airplane, the CH 601 XL. Planes that have the required fixes to avoid problems are properly identified as CH 601 XL B. A modified version of this same basic aircraft (larger canopy, swept rudder, etc) is known as the CH 650.I know the 601 has some safety issues regarding the wing failure. Are there any cases like this or concerns associated with the 701?
