NTSB narrative
The certified flight instructor (CFI) reported that he was in a steep right turn when he heard a "thump" which seemed to come from the tail section of the airplane. He leveled the wings and realized that he was "holding extreme right rudder with the pedal depressed to about three-fourths of its full travel." The CFI flew back to the airport that was 10 miles away. During the final approach to landing, the CFI flew the tai wheel-equipped airplane to within 6 - 12 inches of the runway and let the airspeed bleed off prior to touchdown. He reported that he ran out of right rudder just as all three wheels touched down. The inspection of the airplane revealed that a large section of the left wing's fabric had separated from the airplane. Nine wing ribs plus the main and rear spars from wing station 58 to wing station 176 were visible as a result of the missing wing fabric. A review of the maintenance records indicated that on October 16, 2000, the left wing was repaired and a "fabric patch" was used to repair the wing's fabric.
Probable cause
The left wing skin "fabric patch" separated from the wing ribs and spars for an undetermined reason.

- 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.
