Narrative:

Started to call 11 mi south of flight when engine suddenly lost power and started to run very rough. I didn't call flint until a couple of mins later as I was concerned about my engine, and by then was only 6 mi south of the airport. Shut off engine and glided to a landing. Later found out that a piece of rubber torn loose from 'snorkel' was blocking air to carburetor when rpms reached 1900 FPM. That's the reason I flew into arsa without contacting them first. I don't know if the controller will report this or not, but I thought I would anyway.

Original NASA ASRS Text

Title: UNAUTHORIZED PENETRATION OF AIRSPACE.

Narrative: STARTED TO CALL 11 MI S OF FLT WHEN ENG SUDDENLY LOST PWR AND STARTED TO RUN VERY ROUGH. I DIDN'T CALL FLINT UNTIL A COUPLE OF MINS LATER AS I WAS CONCERNED ABOUT MY ENG, AND BY THEN WAS ONLY 6 MI S OF THE ARPT. SHUT OFF ENG AND GLIDED TO A LNDG. LATER FOUND OUT THAT A PIECE OF RUBBER TORN LOOSE FROM 'SNORKEL' WAS BLOCKING AIR TO CARB WHEN RPMS REACHED 1900 FPM. THAT'S THE REASON I FLEW INTO ARSA WITHOUT CONTACTING THEM FIRST. I DON'T KNOW IF THE CTLR WILL RPT THIS OR NOT, BUT I THOUGHT I WOULD ANYWAY.
