Narrative:

On oct/xa/98 at nearly XX00, I prepared for a short flight in n-number which is a 285 hp 4 place retractable gear aeronautical commander single engine aircraft in which I have logged over 1000 hours since its purchase. At the time, traffic was using runway 25 at sba airport. The plane was poised outside hangar xx near the south end of runway 15. The aircraft was pointed approximately 290 degrees. Prior to start, no radio contact with the control tower had been made. The WX was clear. Engine start was seemingly routine. However, this time the throttle was set inadvertently at near full. To my complete surprise the engine caught at nearly maximum power and before I could respond, the aircraft had crossed the taxiway and runway 15L. I pulled the throttle back and pulled the mixture control back from full rich and the aircraft came to a halt before runway 15R. The aircraft now was under my full control. A tow truck then pushed the aircraft back to the hangar. No damage was done to airport property, my aircraft or any other aircraft. I have been flying for 30 yrs and never experienced any incident similar to this. From this experience, I have learned that a preflight or engine start must include a conscious callout of 'power off' as well as 'mixture full rich,' similar to the callout of gump used prior to landing.

Title: PLT OF AN AERO COMMANDER 200 (AC20) LOST CTL OF THE ACFT DURING ENG START WHEN THE ENG STARTED WITH FULL PWR AND TRAVELED ACROSS A TXWY AND A PARALLEL RWY BEFORE THE PLT COULD REGAIN CTL BY PULLING BACK THE THROTTLE AND MIXTURE CTL.

Narrative: ON OCT/XA/98 AT NEARLY XX00, I PREPARED FOR A SHORT FLT IN N-NUMBER WHICH IS A 285 HP 4 PLACE RETRACTABLE GEAR AERO COMMANDER SINGLE ENG ACFT IN WHICH I HAVE LOGGED OVER 1000 HRS SINCE ITS PURCHASE. AT THE TIME, TFC WAS USING RWY 25 AT SBA ARPT. THE PLANE WAS POISED OUTSIDE HANGAR XX NEAR THE S END OF RWY 15. THE ACFT WAS POINTED APPROX 290 DEGS. PRIOR TO START, NO RADIO CONTACT WITH THE CTL TWR HAD BEEN MADE. THE WX WAS CLR. ENG START WAS SEEMINGLY ROUTINE. HOWEVER, THIS TIME THE THROTTLE WAS SET INADVERTENTLY AT NEAR FULL. TO MY COMPLETE SURPRISE THE ENG CAUGHT AT NEARLY MAX PWR AND BEFORE I COULD RESPOND, THE ACFT HAD CROSSED THE TXWY AND RWY 15L. I PULLED THE THROTTLE BACK AND PULLED THE MIXTURE CTL BACK FROM FULL RICH AND THE ACFT CAME TO A HALT BEFORE RWY 15R. THE ACFT NOW WAS UNDER MY FULL CTL. A TOW TRUCK THEN PUSHED THE ACFT BACK TO THE HANGAR. NO DAMAGE WAS DONE TO ARPT PROPERTY, MY ACFT OR ANY OTHER ACFT. I HAVE BEEN FLYING FOR 30 YRS AND NEVER EXPERIENCED ANY INCIDENT SIMILAR TO THIS. FROM THIS EXPERIENCE, I HAVE LEARNED THAT A PREFLT OR ENG START MUST INCLUDE A CONSCIOUS CALLOUT OF 'PWR OFF' AS WELL AS 'MIXTURE FULL RICH,' SIMILAR TO THE CALLOUT OF GUMP USED PRIOR TO LNDG.

Pilot of an aeronautical commander 200 (AC20) lost control of the aircraft during engine start when the engine started with full power and traveled across a taxiway and a parallel runway before the pilot could regain control by pulling back the throttle and mixture control.
