AN AMERICAN CHAMPION ON TKOF ROLL HAD ERRONEOUS AIRSPD INDICATIONS CAUSED BY THE INCORRECT INSTALLATION OF THE LINES TO THE NEW PITOT PROBE.

Narrative

DURING TKOF THE AIRSPD INDICATOR WAS NOTED TO BE READING EXCESSIVELY HIGH. I WAS FLYING THE ACFT; FROM THE BACK SEAT; WITH ANOTHER QUALIFIED PLT IN THE FRONT SEAT; FOR A PLEASURE FLT. I COULD NOT SEE THE AIRSPD INDICATOR; THE OTHER PLT NOTED THE PROB AT ABOUT 20 FT AGL; STATING THE INDICATED AIRSPD WAS ABOUT 160 MPH. THERE WAS NOT SUFFICIENT ROOM ON THE RWY TO LAND AND THE ACFT WAS HANDLING NORMALLY. I ELECTED TO ABORT THE FLT; USING THE ACTIVE RWY 17; ALSO AT ZZZ THE ACFT HAD JUST HAD A NEW PITOT/STATIC TUBE INSTALLED BY ZZZ FBO. ACFT AND ENG MAINT; ON THE FIELD AT ZZZ. THIS WAS THE FIRST FLT AFTER THAT REPAIR. I DETERMINED THAT THE AIRSPD INDICATOR WAS INDICATING EXACTLY OPPOSITE OF WHAT IT SHOULD AND WE FLEW A NORMAL APCH AND LNDG; WITHOUT INCIDENT. THE ACFT WAS TAKEN IMMEDIATELY TO ZZZ FBO; WHERE IT WAS DETERMINED THAT THE PITOT AND STATIC LINES WERE REVERSED. THE MAINT PERSONNEL AND BUSINESS MGR DID NOT APPEAR AT ALL CONCERNED ABOUT THEIR MISTAKE. THERE ARE VERY LIMITED MAINT OPTIONS AT ZZZ FOR GA ACFT (FLT TRAINING CLUBS IN PARTICULAR). IT TOOK LESS THAN 5 MINS TO CORRECT THIS PROB AND TEST THE SYS.
