Northrop N-23 Pioneer

The pilot did not hold a type rating or written authorization to act as pilot in command. The copilot did not hold a type rating or written authorization to act as second in command and his medical had expired. The aircraft did not have an airworthiness certificate nor had a special flight permit been issued. The left propeller went into reverse during the initial climb due to corrosion and deterioration of the wiring that controlled the propeller. The aircraft crashed out of control after colliding with power lines during takeoff. It struck the ground and went through a fence then down a slope and over an embankment. The aircraft then bounced across a street while turning around and colliding with a power line pole tail first. The aircraft had traveled about 537 feet from initial ground contact. All 3 engines were still producing power when the aircraft came to rest. Both occupants escaped uninjured.
