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.)
