The NTSB's narrative final · quoted from the NTSB record
As the airplane made a full flap approach to the runway, the pilot 'felt a bump,' the right flap retracted, and the airplane rolled abruptly to the right. The pilot added full power and left aileron but it had no effect. The airplane drifted off the right side of the runway, dragging the wing tip, then cartwheeled and nosed into the ground. Postaccident inspection revealed the right hand flap rod (p/n F-659) had failed, causing a split flap condition. The failed actuator rod was made of aluminum tubing threaded at each end. The pilot said, 'Wall thickness at the threaded ends is thin,' and the part should be made of steel. Vans Aircraft, Inc., said 'the failure was associated with poor workmanship rather than materials defect or structural design...the original builder had not enlarged the hole required in the fuselage large enough to prevent the rod from 'scraping' during flap extension. The continued scraping had eventually worn away the entire side of the rod and resulted in total failure.'
