Narrative:

Just after G/south interception on the ILS 19 approach at mci, while giving IFR dual to a private pilot seeking his instrument rating, the engine of our small aircraft quit suddenly. I took control of the aircraft, pulling up to slow to best glide speed, and managed to stay on G/south while I troubleshot the problem and called tower to inform them that I had lost power, but still could make the runway. Before they could respond, power had returned. I made an uneventful landing and taxied to the ramp. No mechanic was available, so I called the mechanic at my home base. He, like I, suspect carburetor ice or perhaps ice crystals in the fuel. I could detect no fuel contamination, but had the airplane refueled regardless, before an uneventful flight home. XXXX of the kansas city FSDO called me before I left mci and agreed it was safe to fly home.

Title: MOMENTARY ENGINE FAILURE WHILE ON APCH.

Narrative: JUST AFTER G/S INTERCEPTION ON THE ILS 19 APCH AT MCI, WHILE GIVING IFR DUAL TO A PVT PLT SEEKING HIS INSTRUMENT RATING, THE ENG OF OUR SMA QUIT SUDDENLY. I TOOK CONTROL OF THE ACFT, PULLING UP TO SLOW TO BEST GLIDE SPD, AND MANAGED TO STAY ON G/S WHILE I TROUBLESHOT THE PROB AND CALLED TWR TO INFORM THEM THAT I HAD LOST PWR, BUT STILL COULD MAKE THE RWY. BEFORE THEY COULD RESPOND, PWR HAD RETURNED. I MADE AN UNEVENTFUL LNDG AND TAXIED TO THE RAMP. NO MECH WAS AVAILABLE, SO I CALLED THE MECH AT MY HOME BASE. HE, LIKE I, SUSPECT CARB ICE OR PERHAPS ICE CRYSTALS IN THE FUEL. I COULD DETECT NO FUEL CONTAMINATION, BUT HAD THE AIRPLANE REFUELED REGARDLESS, BEFORE AN UNEVENTFUL FLT HOME. XXXX OF THE KANSAS CITY FSDO CALLED ME BEFORE I LEFT MCI AND AGREED IT WAS SAFE TO FLY HOME.
