NTSB Narrative Summary Released at Completion of Accident

The pilot of the Cessna 206, N5244Z, had reported to the local controller that he was entering Lake Hood at the public ramp and was water taxiing foe a southeast departure on the lake. Approximately one minute later the pilot of the Cessna 180, N5020E, reported to the local controller that he was at the east shore of Lake Spenard requesting a west departure. The pilot of the C-180 was advised to 'hold short of the west, advise ready.' The pilot of the C-206 was cleared for takeoff, and the pilot of the C-180 was again advised to hold short; however the C-180 pilot did not acknowledge the radio transmission. The C-206 departed and began a climb over the canal separating the two lakes that comprise the seaplane base. The C-180 departed in a westbound direction. The airplanes collided about 100 feet above the canal. The right horizontal stabilizer and elevator of the C-206 was struck by the right wing of the C-180. The C-206 returned and landed safely. The pilot of the C-180 continued his departure and returned to the seaplane base the next day.

NTSB Probable Cause Narrative

The pilot of the Cessna 180, N5020E, disregard of an air traffic control clearance/instruction to hold short. A factor in the accident was the failure of both pilots to maintain an adequate visual lookout for other aircraft.
