Probable cause

Failure of the pilot to perform the emergency gear extension procedure to assure that the gear was down and locked. Factors related to the accident were: low oil pressure in the right eng, failure of both voltage regulators, and the low level of charge in the battery.

Analysis

During flt, the plt noted that oil pressure in the rgt eng had dropped to the red line, so he shut down & feathered the eng. He stated that after entering traffic to lnd, he 'lowered' the gear, then noted that the radar & radios became inop (as electrical power was lost). Though he heard & felt the gear extend, he did not see illumination of the downlock lights. The plt made a 360 deg turn to get spacing behind another acft, then contd the apch to land. During the landing, the gear collapsed & the acft was damaged. An exam of the rgt eng revealed that the low oil pressure was due to a piece of carbon under the oil pressure relief valve seat. Both alternators tested satisfactorily; however, both voltage regulators had failed internally & both alternator circuit breakers were popped.
