NTSB narrative
The non multi-engine rated pilot needed to make an unscheduled landing in his twin-engine airplane to "check fuel." While on final approach in a crosswind, the airplane drifted to the left of runway centerline and the pilot compensated with right rudder input and increased power on both engines. The right engine did not power up immediately and the airplane was pulled to the right of the runway centerline. The pilot said that he was unable to get the airplane back in line with the runway before it hit the ground. Witnesses said the airplane did not sound right and was weaving back and forth as it approached the runway with its right wing low. The airplane landed, then bounced several times before it came to a complete stop. Examination of the airplane revealed that it had sustained substantial damage to the right wing and tail cone. The right main and nose landing gear were also damaged, and all three propeller blades on the right engine were bent aft at the tips. The airplane was equipped with three fuel tanks in each wing; one inboard of the engine nacelle and two outboard of the engine nacelle. The right wing's two outboard tanks had been disabled and only the right inboard tank was being utilized at the time of the accident. It appeared to be less than a quarter full. Approximately two cups of what appeared to be a mixture of brown sludgy debris, water, and blue fuel were drained from the main fuel strainer in the fuselage.
Probable cause
The pilot's failure to maintain control of the twin-engine airplane while landing. Contributing to the accident were the crosswind and partial loss of power on the right engine.

- 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.
