What was found
DISMANTLED LEFT WING FOR THE PURPOSE OF RECOVERING. AS A PRECAUTION, THE WING SPAR ATTACHMENT FITTINGS WERE MAGNAFLUXED. THE LEFT FRONT WING SPAR ATTACHMENT FITTING WAS FOUND TO HAVE SEVERAL IMPERFECTIONS IN THE WELDED AREA OF BOTH THE TOP AND BOTTOM GUSSETS. THE FITTING WAS REPLACED WITH A NEW PART. IT APPEARS SOME OF THE IMPERFECTIONS ARE FROM PITTING (CORROSION) AND SOME ARE VERY SMALL CRACKS. RECOMMEND NDT AT EACH TIME OF RECOVERING OR REBUILDING AFTER WING IMPACT OF ROLL-OVER DAMAGE.
