I was conducting a flight under VFR from sav to sua in a mooney M20C. The entire flight was unremarkable except for the landing. On approach to sua the aircraft was responding normally to control inputs. Upon touching down with main gear and just before front gear touchdown, the aircraft abruptly initiated an uncontrolled departure to approximately 10 ft above the surface. Since the aircraft was at stall speed, it immediately began a rapid descent to the surface at which time full power was applied and elevator inputs were applied to prevent the impending collision with the surface. The aircraft nosed over and began to recover. It is unknown to me why the aircraft launched into the air after landing. Subsequent to recovering control of the craft it was set down on the paved surface and normal runout was maintained to decelerate using mild braking. The taxi roll was initiated upon clearance and concluded at the home base hangar. There was a 3 min cool down for the turbo and shutdown. After retrieving the tow bar and attaching it to the front wheel I noticed the outermost 2-3 inches of the propeller was bent back due to ground impact. I was confounded at the obvious propeller strike because I did not hear or feel the damage occur. Human performance considerations: I am not aware of any judgements I could have made to alter the events. I believe the actions I did take prevented a far more serious outcome. I am, however, regretful of the complacency that I may have exhibited in the fact that I was unprepared for the departure. Possibly a slight increase in reaction time may have prevented the incident. I believe that I did not give the mooney the undiminished attention I should have. I am skillful in the operation of much larger complicated aircraft. Previous flight in this type did not manifest any severe or unusual characteristics. I was also plagued by a headache at the time of the landing possibly from an unusually high carbon monoxide content in the cabin air. I had noticed the faint odor of exhaust gas periodically throughout the flight. I am also not aware if this had anything to do with the incident.

Title: MO20 PLT LOST CTL OF ACFT ON LNDG.
Narrative: I WAS CONDUCTING A FLT UNDER VFR FROM SAV TO SUA IN A MOONEY M20C. THE ENTIRE FLT WAS UNREMARKABLE EXCEPT FOR THE LNDG. ON APCH TO SUA THE ACFT WAS RESPONDING NORMALLY TO CTL INPUTS. UPON TOUCHING DOWN WITH MAIN GEAR AND JUST BEFORE FRONT GEAR TOUCHDOWN, THE ACFT ABRUPTLY INITIATED AN UNCTLED DEP TO APPROX 10 FT ABOVE THE SURFACE. SINCE THE ACFT WAS AT STALL SPD, IT IMMEDIATELY BEGAN A RAPID DSCNT TO THE SURFACE AT WHICH TIME FULL PWR WAS APPLIED AND ELEVATOR INPUTS WERE APPLIED TO PREVENT THE IMPENDING COLLISION WITH THE SURFACE. THE ACFT NOSED OVER AND BEGAN TO RECOVER. IT IS UNKNOWN TO ME WHY THE ACFT LAUNCHED INTO THE AIR AFTER LNDG. SUBSEQUENT TO RECOVERING CTL OF THE CRAFT IT WAS SET DOWN ON THE PAVED SURFACE AND NORMAL RUNOUT WAS MAINTAINED TO DECELERATE USING MILD BRAKING. THE TAXI ROLL WAS INITIATED UPON CLRNC AND CONCLUDED AT THE HOME BASE HANGAR. THERE WAS A 3 MIN COOL DOWN FOR THE TURBO AND SHUTDOWN. AFTER RETRIEVING THE TOW BAR AND ATTACHING IT TO THE FRONT WHEEL I NOTICED THE OUTERMOST 2-3 INCHES OF THE PROP WAS BENT BACK DUE TO GND IMPACT. I WAS CONFOUNDED AT THE OBVIOUS PROP STRIKE BECAUSE I DID NOT HEAR OR FEEL THE DAMAGE OCCUR. HUMAN PERFORMANCE CONSIDERATIONS: I AM NOT AWARE OF ANY JUDGEMENTS I COULD HAVE MADE TO ALTER THE EVENTS. I BELIEVE THE ACTIONS I DID TAKE PREVENTED A FAR MORE SERIOUS OUTCOME. I AM, HOWEVER, REGRETFUL OF THE COMPLACENCY THAT I MAY HAVE EXHIBITED IN THE FACT THAT I WAS UNPREPARED FOR THE DEP. POSSIBLY A SLIGHT INCREASE IN REACTION TIME MAY HAVE PREVENTED THE INCIDENT. I BELIEVE THAT I DID NOT GIVE THE MOONEY THE UNDIMINISHED ATTN I SHOULD HAVE. I AM SKILLFUL IN THE OP OF MUCH LARGER COMPLICATED ACFT. PREVIOUS FLT IN THIS TYPE DID NOT MANIFEST ANY SEVERE OR UNUSUAL CHARACTERISTICS. I WAS ALSO PLAGUED BY A HEADACHE AT THE TIME OF THE LNDG POSSIBLY FROM AN UNUSUALLY HIGH CARBON MONOXIDE CONTENT IN THE CABIN AIR. I HAD NOTICED THE FAINT ODOR OF EXHAUST GAS PERIODICALLY THROUGHOUT THE FLT. I AM ALSO NOT AWARE IF THIS HAD ANYTHING TO DO WITH THE INCIDENT.
