Narrative:

Subsequent to a hard landing during short field technique practice, the nose gear of the aircraft collapsed causing the nose to touch the ground and the propellers as well. Substantial damage was reported to the engines and nose section of the aircraft. Callback conversation with reporter revealed the following information: practice short field lndgs, approach speed slow, student pilot pulled power off at threshold inducing a high sink rate. Instructor pilot tried to add power to catch it, but too late and aircraft hit hard on all 3 landing gear. Takeoff was normal with gear retraction normal, but when landing the nose gear collapsed causing damage to the nose gear, nose cone, firewall, propellers and engines. Then, when towing the aircraft, the main gear collapsed due to loss of hydraulic pressure. The pressure loss was due to nose gear collapse cutting a hydraulic line. FAA investigated with no further action.

Original NASA ASRS Text

Title: HARD LNDG. NOSE GEAR COLLAPSE.

Narrative: SUBSEQUENT TO A HARD LNDG DURING SHORT FIELD TECHNIQUE PRACTICE, THE NOSE GEAR OF THE ACFT COLLAPSED CAUSING THE NOSE TO TOUCH THE GND AND THE PROPS AS WELL. SUBSTANTIAL DAMAGE WAS RPTED TO THE ENGS AND NOSE SECTION OF THE ACFT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: PRACTICE SHORT FIELD LNDGS, APCH SPD SLOW, STUDENT PLT PULLED PWR OFF AT THRESHOLD INDUCING A HIGH SINK RATE. INSTRUCTOR PLT TRIED TO ADD PWR TO CATCH IT, BUT TOO LATE AND ACFT HIT HARD ON ALL 3 LNDG GEAR. TKOF WAS NORMAL WITH GEAR RETRACTION NORMAL, BUT WHEN LNDG THE NOSE GEAR COLLAPSED CAUSING DAMAGE TO THE NOSE GEAR, NOSE CONE, FIREWALL, PROPS AND ENGS. THEN, WHEN TOWING THE ACFT, THE MAIN GEAR COLLAPSED DUE TO LOSS OF HYD PRESSURE. THE PRESSURE LOSS WAS DUE TO NOSE GEAR COLLAPSE CUTTING A HYD LINE. FAA INVESTIGATED WITH NO FURTHER ACTION.
