NTSB narrative
The flight instructor was giving instruction in the multiengine, retractable-landing gear-equipped airplane. On the downwind leg in the pattern, he asked the pilot under instruction to perform a simulated single-engine emergency landing with the left engine shutdown.
It was the pilot under instruction's first training flight in a multiengine airplane, and he asked a series of questions of the flight instructor during the procedure. The instructor reported that they both became distracted and forgot to extend the landing gear. The airplane landed with the landing gear retracted and came to rest on the runway.
The airplane sustained substantial damage to the wingspar and longerons.
The flight instructor reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The pilot under instruction’s failure to extend the landing gear and the flight instructor’s inadequate supervision and failure to ensure that the landing gear was extended.

- 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. 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.
