Narrative:

Wind 320 degrees at 22 KTS, gusting to 30+ KTS. As pilot flared to touchdown, 'bottom fell out' causing sudden drop onto runway. Gear collapsed causing much damage. After event began, it progressed too suddenly for evasive action to prevail. Believe loss of lift probably due to windshear at runway surface. Possibly approach at airspeed much higher than normal, 1.3 vso would have lessened drop. Callback conversation with reporter revealed the following information: reporter wrote to ASRS as he was unable to find the phone number. He was unhappy. FAA is investigating the incident and he would like his identify strip. Analyst callback revealed the aircraft is a mooney, the gear damage is extensive. Reporter is an instructor.

Original NASA ASRS Text

Title: MOONEY PLT HAS WINDSHEAR PROB WITH RESULTING HARD LNDG AND GEAR COLLAPSE.

Narrative: WIND 320 DEGS AT 22 KTS, GUSTING TO 30+ KTS. AS PLT FLARED TO TOUCHDOWN, 'BOTTOM FELL OUT' CAUSING SUDDEN DROP ONTO RWY. GEAR COLLAPSED CAUSING MUCH DAMAGE. AFTER EVENT BEGAN, IT PROGRESSED TOO SUDDENLY FOR EVASIVE ACTION TO PREVAIL. BELIEVE LOSS OF LIFT PROBABLY DUE TO WINDSHEAR AT RWY SURFACE. POSSIBLY APCH AT AIRSPD MUCH HIGHER THAN NORMAL, 1.3 VSO WOULD HAVE LESSENED DROP. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR WROTE TO ASRS AS HE WAS UNABLE TO FIND THE PHONE NUMBER. HE WAS UNHAPPY. FAA IS INVESTIGATING THE INCIDENT AND HE WOULD LIKE HIS IDENT STRIP. ANALYST CALLBACK REVEALED THE ACFT IS A MOONEY, THE GEAR DAMAGE IS EXTENSIVE. RPTR IS AN INSTRUCTOR.
