What happened
The pilot reported that all preflight inspections, engine starts, taxiing, and pre-takeoff checks were completed normally. Shortly after takeoff, at an altitude of approximately 150 feet, the right engine seized immediately.
Following the engine failure, the pilot was unable to safely turn the aircraft back toward the airport for a landing. To maintain directional control, the pilot navigated between rising terrain to the left and a populated area situated near a river to the right. The pilot chose to turn into the dead engine to steer toward the river.
While over the water, the pilot encountered a dam in one direction, which presented an obstacle that could not be cleared due to insufficient climb capability. A turn in the opposite direction revealed high-tension wires strung across the river. Because the aircraft lacked the altitude to fly over or under these wires, the pilot executed another steep turn to remain over the river and avoid the obstructions.
This maneuver resulted in a loss of remaining altitude, leading the pilot to accept a water landing. Just before impact with the water, the pilot leveled the wings and pulled the nose up to reduce the force of the impact. The pilot was not injured.
The investigation
An examination of the wreckage revealed that the landing gear was in the down position. The pilot stated he could not recall raising the landing gear prior to takeoff.
