I have a Rascal 40 and have had the motor mount and landing gear problems. Fixed those and love the airplane. There is one other area that could be a potential problem that might have had something to do with the crash mentioned above. If you over tighten the wing hold down bolts, it could weaken or break the mount that contains the blind nuts, that the bolts screw into. If that mount failed, the wing would depart the airplane.
