## Analysis

AFTER TKOF, THE PLT LEVELED AT ABOUT 1500' & ADJUSTED THE PWR TO A LOW CRUISE SETTING. A SHORT TIME LATER, THE ENG BGN MISSING & SUBSEQUENTLY LOST ALL PWR. THE PLT FOLLOWED THE EMERG PROCEDURES, BUT WAS UNABLE TO RESTART THE ENG. HE MANUEVERED THE ACFT TO LAND ON A GOLF COURSE, BUT DELAYED EXTENDING THE LANDING GEAR TO CLEAR OVER PWR LINES & TREES. AFTER CLEARING THE OBSTRUCTIONS, HE LOWERED THE GEAR SWITCH, BUT THE ACFT TOUCHED DOWN BEFORE THE GEAR WAS FULLY EXTENDED. A CHECK OF THE ENG REVEALED THE MAGNETOS WERE NOT PROVIDING IGNITION. EVIDENCE OF CARBON TRACKING WAS PRESENT IN BOTH MAGNETOS. WHEN THE MAGNETOS WERE CHECKED, A SPARK WAS OBSERVED ARCING ACROSS THE MAGNETO BARS. THE MANUFACTURER RECOMMENDED THE MAGNETOS (SLICK MODEL 622R) BE SERVICED EACH 500 HRS. THE MAGS IN THIS ACFT HAD A TOTAL FLT TIME OF 556 HRS SINCE INSTALLATION.
