Incident Summary
A pilot reported forgetting to extend the landing gear during a short field landing practice. The aircraft was configured with the manifold pressure set at approximately 15 inches of mercury (in. Hg) during the approach.
Pilot Actions
The pilot stated that he was practicing a short field landing with the power set at about 15 in. Hg MAP. He acknowledged that he forgot to lower the landing gear before touchdown.
Aircraft Systems
The pilot noted that the aircraft's gear warning system does not function unless the power is reduced to 12 in. Hg MAP or below. During the approach, the power setting of 15 in. Hg MAP was above that threshold, so the warning did not activate.
Pilot Comments
The pilot expressed the opinion that the accident could have been prevented if he had performed a GUMP check—an acronym for Gas, Undercarriage, Mixture, Props—prior to landing.
