NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
The flight instructor in the twin-engine airplane reported that, during the second simulated single engine failure approach, the pilot under instruction reduced the left engine power setting to 12 inches of manifold pressure, which activated the landing gear auditory warning horn. On downwind, the student performed his prelanding checks and asked the instructor if he should deploy the landing gear. Since the student was struggling to maintain altitude, the student was instructed to delay the action, and deploy the landing gear during the final landing checks. Shortly after turning final, the student performed the final landing checks and provided verbal cues of completion but did not include the landing gear check.
