Narrative:

I was acting as flight instructor and PIC on the flight in a tbm 700, from apa to ase. The aircraft owner, a licensed pilot, was acting as 'PF.' we had completed a VOR DME approach to visual conditions and were cleared for a visual approach to ase runway 15. The approach was stabilized with landing gear and flaps in the landing position. The approach was normal until approximately 100 ft above the runway, at which time the airplane encountered a probable windshear or wake turbulence condition, causing rapid-roll tendencies right and left. As the PF began his landing flare at about 15 ft above the runway, the left wing dropped rapidly, combined with a sudden high sink rate. As I took control of the airplane applying corrective rudder, aileron, pitch, and power corrections, the left wingtip struck the runway, causing damage to the left wingtip, aileron, and trailing edge wing flap. The airplane was taxied to the ramp where we made a visual inspection of the damage, and I determined that the airplane should not be flown without further inspection by maintenance personnel and probable repairs. There was no apparent damage to structural components, such as, landing gear box, wing spars, or fuel tanks. There was no fuel leakage, no propeller strike or injuries to persons on board. (Note -- tower had winds of 000 degrees/00 KTS, then 160 degrees/10 + 17 KTS, and then back to 300 degrees/7 KTS. Not reported to me on the approach.)

Title: WINGTIP STRIKE AFTER A LOSS OF ACFT CTL DURING FLARE IN A TBM 700 ON RWY 15 AT ASE, CO.

Narrative: I WAS ACTING AS FLT INSTRUCTOR AND PIC ON THE FLT IN A TBM 700, FROM APA TO ASE. THE ACFT OWNER, A LICENSED PLT, WAS ACTING AS 'PF.' WE HAD COMPLETED A VOR DME APCH TO VISUAL CONDITIONS AND WERE CLRED FOR A VISUAL APCH TO ASE RWY 15. THE APCH WAS STABILIZED WITH LNDG GEAR AND FLAPS IN THE LNDG POS. THE APCH WAS NORMAL UNTIL APPROX 100 FT ABOVE THE RWY, AT WHICH TIME THE AIRPLANE ENCOUNTERED A PROBABLE WINDSHEAR OR WAKE TURB CONDITION, CAUSING RAPID-ROLL TENDENCIES R AND L. AS THE PF BEGAN HIS LNDG FLARE AT ABOUT 15 FT ABOVE THE RWY, THE L WING DROPPED RAPIDLY, COMBINED WITH A SUDDEN HIGH SINK RATE. AS I TOOK CTL OF THE AIRPLANE APPLYING CORRECTIVE RUDDER, AILERON, PITCH, AND PWR CORRECTIONS, THE L WINGTIP STRUCK THE RWY, CAUSING DAMAGE TO THE L WINGTIP, AILERON, AND TRAILING EDGE WING FLAP. THE AIRPLANE WAS TAXIED TO THE RAMP WHERE WE MADE A VISUAL INSPECTION OF THE DAMAGE, AND I DETERMINED THAT THE AIRPLANE SHOULD NOT BE FLOWN WITHOUT FURTHER INSPECTION BY MAINT PERSONNEL AND PROBABLE REPAIRS. THERE WAS NO APPARENT DAMAGE TO STRUCTURAL COMPONENTS, SUCH AS, LNDG GEAR BOX, WING SPARS, OR FUEL TANKS. THERE WAS NO FUEL LEAKAGE, NO PROP STRIKE OR INJURIES TO PERSONS ON BOARD. (NOTE -- TWR HAD WINDS OF 000 DEGS/00 KTS, THEN 160 DEGS/10 + 17 KTS, AND THEN BACK TO 300 DEGS/7 KTS. NOT RPTED TO ME ON THE APCH.)
