NTSB Narrative Summary Released at Completion of Accident
On approach the pilot selected to extend the landing gear, but he did not get a green light to confirm all three landing gear were down and locked. He checked the electrical fuses and performed several cycles of gear extension with no change to the indication of the landing gear position. He pumped the emergency gear extension hand pump. He advised air traffic control and was instructed to perform several low fly-bys. Tower and fire rescue personnel visually verified that all three landing gear were down. As the airplane's main landing gear touched the runway in a soft field-landing configuration, the right main landing gear collapsed. The pilot stated that he pumped the emergency gear extension pump handle until he felt resistances. He could not remember how many strokes exactly he performed, somewhere from 2 to 3 strokes. The main landing gears were operationally checked once with the airplane's own battery power and twice with the emergency landing gear extension hydraulic hand pump for manual extension of landing gears. The main landing gears extended and locked into position within 12 to 15 pumps of the emergency landing gear extension hydraulic hand pump. No defects were observed in the operation of the extension and locking of the main landing gears by hand pump. An examination of the main landing left and right gear actuators and locking systems revealed no anomalies. Avion's chief flight instructor stated close to a month before the accident, on the accident airplane, he had to perform an emergency extension of the landing gear by the hand pump; more so, it took anywhere from 10 to 20 pumps to lower the gear and into the lock position. According to the chief pilot who checked out the pilot only verbal instructions on how to extend the landing gear by hand pump was given during the check ride in the airplane.
NTSB Probable Cause Narrative
Pilot's improper emergency landing gear extension procedure which resulted in the right main landing gear not locking in the down position subsequent right main landing gear collapsing on landing.
