Narrative:
The flight instructor stated that after leaving St. Petersburg, he experienced radio problems and the alternator tripped off line. The instructor said he could not reset it, so he turned the master switch off, and continued the flight. Prior to landing, the instructor said that he turned on the master switch, extended the landing gear, visibly checked that the left gear was down, but did not get a gear light. During landing, the instructor said the right main gear settled to the runway and gave way, with the airplane exiting the runway. The instructor said that he never attempted to manually pump the gear down. The FAA inspector who conducted the post crash examination of the airplane said that he found the airplane with the left main gear extended and locked, the nose wheel sheared off, and the right gear collapsed into the gear well. The inspector also stated that witnesses told him that they saw the right main gear trailing prior to landing. The inspector stated that the aircraft battery was almost depleted of electrical energy, and the low voltage warning light was on. According to the inspector, thirty degrees of flaps was selected, but the flaps were extended about 10 to 15 degrees, and the manual extension pump for the landing gear was stowed, with no evidence of recent use. The inspector said that after supporting the aircraft and starting the engine, no electrical problems were found.

Probable Cause: the pilot's failure to ensure that the landing gear was down and locked following loss of electrical power for undetermined reasons, resulting in substantial damage to the airplane when the right main landing gear collapsed upon landing.
