Aviation Accident Summary MIA06CA097

Lake Wales, FL, USA

Aircraft #1

N1051L

Lake LA-4-200

Analysis

The pilot stated that during his arrival to the airport, on the previous day, he noted the center of the runway was sandy and soft due to the drought. Before the departure, he walked a third of the runway to check the surface conditions. He decided to stay off the middle and favor the grassier side of the runway; however, he knew it would be bumpier during the takeoff roll. He elected to depart from runway 18, which is slightly downhill. The breeze was from the west-southwest. He performed a soft field takeoff while staying on the west side of the runway. The takeoff roll was bumpy and noted the airspeed indicator reached 55 mph, the rotation speed was 60 mph. The airplane encountered a bump, the airspeed drop to 50 mph then increased to 55 mph. The airplane encountered another bump and the airspeed dropped to 50 mph and increased again. By this time, the airplane crossed a road located toward the end of the runway, struck a berm, which sheared the nose wheel. The airplane became airborne with insufficient airspeed to fly. The left wing contacted the ground and the airplane spun 180 degrees, skidding backward before coming to a stop. The pilot stated that there were no mechanical failures or malfunctions with the airplane or any of its systems prior to the accident.
