The NTSB's narrative final · quoted from the NTSB record
According to the pilot, he had been experiencing electrical problems for the majority of his flight. The pilot reported that he entered a downwind for runway 29R, lowered his landing gear and set 15 degrees flaps. The pilot noticed that the flap indicator was not down so he raised the flaps lever to avoid problems later. The pilot did not visually verify that his gear was down. During the landing flare, both propellers came in contact with the ground and the airplane slid along the runway for several hundred feet, substantially damaging a bulkhead.
