wing roots to be ultrasonic/X-ray examined before any further flight.
The challenge may be that there might not be an approved procedure for such an inspection. 'Doesn't mean it would not be a good idea, but an inspector qualified to use these methods probably want's a procedure to refer to. The Piper SB I referenced states 10 power magnifier, and dye penetrant. That can be called upon as an approved method (and it pretty common). The challenge will be that by the time you get the plane that far apart, there will be a large labour bill already, and risk of damage resulting from bolt and wing removal (I struggled with this, when I did the inspection). And, if you find a defect, now what?
Before I undertook this inspection, I'd be calling Piper to ask about replacement parts, should they found to be needed. Based upon my experience with the repair of a Piper Seneca I many years back, I'd be holding my breath....
