ARTCC CTLR ASSISTS PLT TO A SAFE LNDG AFTER PLT SUFFERED FROM HYPOXIA AND BECAME DISORIENTED BECAUSE OF A LACK OF OXYGEN.

Narrative

ACFT X EXPERIENCED OXYGEN PROBS AND WAS DISORIENTED WITH HYPOXIA REQUESTING DSCNT FROM FL250 TO 13000 FT. I ISSUED THE CLRNC BUT ACFT X COULDN'T DSND THE ACFT DUE TO HIS INABILITY TO FOCUS. A FLT INSTRUCTOR CAME TO THE SECTOR AND TALKED THE ACFT INTO A DSCNT AND THE PLT RECOVERED; CHANGED HIS DEST TO A CLOSER ARPT AND LANDED SAFETY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT A 400 SERIES CESSNA PLT AT FL250 SAID HE WAS BECOMING DISORIENTED WITH HYPOXIA BECAUSE OF OXYGEN PROBS AND REQUESTED ASSISTANCE. THE RPTR SAID HE IMMEDIATELY ISSUED A DSCNT CLRNC TO THE PLT. THE PLT SAID HE COULDN'T DSND BECAUSE HE WASN'T ABLE TO FOCUS ON WHAT HE WAS DOING. THE CTLR CALLED THE SUPVR AND ASKED HIM TO FIND SOMEONE FAMILIAR WITH C414 ACFT. HE SAID HE KEPT THE PLT CONSCIOUS BY TALKING TO HIM AND ASKING QUESTIONS. THE SUPVR LOCATED A CTLR QUALIFIED AND TYPE RATED IN TWIN CESSNAS TO ASSIST. THE PLT CTLR INSTRUCTED THE PLT TO DISENGAGE HIS AUTOPLT WHICH WOULD START THE ACFT DOWN. AT AROUND 16000 FT THE PLT STARTED TO REGAIN FULL CONSCIOUSNESS. IT WAS LATER LEARNED THAT A CIRCUIT BREAKER HAD CAUSED THE OXYGEN PROB. THE ACFT LANDED SAFELY 25 NM NE OF PGA ARPT. THE PLT WAS FLYING ALONE WITH NO PAX.
