NTSB narrative
While the pilot was practicing takeoffs and landings in the recently-purchased airplane, he performed one landing that was "a pretty good jolt," but "not extraordinary." Following the flight, the pilot noticed damage to the left wing's upper skin. Further examination revealed that a portion of the left wing rib cap was fractured, and that there were two sets of double-drilled, overlapping rivet holes that matched up with holes partially drilled into a false spar. The false spar was covered with a green (preservative) paint, while the partially-drilled holes were not. The rib cap fracture surface exhibited fatigue cracking that did not extend into the overlapping rivet holes. A review of the airplane's maintenance logs revealed no evidence of repair to the affected area. The airplane, which was manufactured in 1971, had 5,529 hours of operating time.
Probable cause
An undocumented, improper repair attempt, which subsequently resulted in fatigue cracking to the rib cap.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
