Narrative:

Event occurred approximately 10 NM nne of sav international airport. After flying northeast at 5500 ft MSL, I noticed the scattered layer below us up ahead was about to become broken so I descended with carburetor heat on and partial power below the scattered layer before it became broken. I was at 1200 ft. The visibility ahead was deteriorating (still VFR) so I opted to make a 180 degree turn and land somewhere close. My tachometer had just quit and the engine was running rough. I had no option but to penetrate the sav arsa before the engine quit running. As I orbited the airport watching for light gun signals I tried to increase power and the engine hardly responded. I had to land before receiving a signal from tower. No conflicting traffic. Lost tachometer, engine ran rough, thought it was going to die/quit. VFR flight without radio. Overflew field, watching for light gun signals from tower, no response (from tower). Engine was losing power, had to land before tower recognized me. After landing tower still did not notice me, or the aircraft. I walked to tower, explained. They said they never saw me. WX was deteriorating at time and I had no option but to penetrate and land at the sav arsa.

Original NASA ASRS Text

Title: NORDO TFC MAKES AN UNAUTH PENETRATION OF AIRSPACE IN PROX OF ARSA AND ATA, PERFORMS UNAUTH LNDG WHILE WATCHING FOR SIGNS OF TWR SIGNAL LIGHT CTL.

Narrative: EVENT OCCURRED APPROX 10 NM NNE OF SAV INTL ARPT. AFTER FLYING NE AT 5500 FT MSL, I NOTICED THE SCATTERED LAYER BELOW US UP AHEAD WAS ABOUT TO BECOME BROKEN SO I DSNDED WITH CARB HEAT ON AND PARTIAL PWR BELOW THE SCATTERED LAYER BEFORE IT BECAME BROKEN. I WAS AT 1200 FT. THE VISIBILITY AHEAD WAS DETERIORATING (STILL VFR) SO I OPTED TO MAKE A 180 DEG TURN AND LAND SOMEWHERE CLOSE. MY TACHOMETER HAD JUST QUIT AND THE ENG WAS RUNNING ROUGH. I HAD NO OPTION BUT TO PENETRATE THE SAV ARSA BEFORE THE ENG QUIT RUNNING. AS I ORBITED THE ARPT WATCHING FOR LIGHT GUN SIGNALS I TRIED TO INCREASE PWR AND THE ENG HARDLY RESPONDED. I HAD TO LAND BEFORE RECEIVING A SIGNAL FROM TWR. NO CONFLICTING TFC. LOST TACHOMETER, ENG RAN ROUGH, THOUGHT IT WAS GOING TO DIE/QUIT. VFR FLT WITHOUT RADIO. OVERFLEW FIELD, WATCHING FOR LIGHT GUN SIGNALS FROM TWR, NO RESPONSE (FROM TWR). ENG WAS LOSING PWR, HAD TO LAND BEFORE TWR RECOGNIZED ME. AFTER LNDG TWR STILL DID NOT NOTICE ME, OR THE ACFT. I WALKED TO TWR, EXPLAINED. THEY SAID THEY NEVER SAW ME. WX WAS DETERIORATING AT TIME AND I HAD NO OPTION BUT TO PENETRATE AND LAND AT THE SAV ARSA.

NORDO traffic makes an unauthorized penetration of airspace in proximity of arsa and air traffic area, performs unauthorized landing while watching for signs of tower signal light control.
