Narrative:

Treasure cay airport (myat) is a non twred airport and has no txwys. As I prepared for departure, I determined the wind favored runway 14, so I had to back-taxi the length of the runway. On 122.8, the CTAF, I announced 'treasure cay traffic, chieftain is about to back-taxi. Is anyone inbound to treasure cay?' receiving no response, I looked both ways for traffic and then proceeded onto the runway for my back-taxi. The sun was low in the sky and made it difficult to see toward the approach end of runway 14. As I entered the runway, I announced on CTAF 'treasure traffic chieftain back-taxiing for departure on runway 14.' when I completed my turn onto the runway, I saw something move near the approach end of runway 14 (the far end of the runway from my position), and a passenger shouted 'there's one landing!' I immediately turned around and expedited off of the runway while announcing on CTAF 'chieftain clearing the runway at treasure, aircraft landing are you on frequency?' after I cleared the runway the other plane landed and I again asked if he was on frequency. He responded by saying 'yes I am and I answered each of your calls, didn't you hear me?' I told him no and that I suspected his transmitter had not been working. I then departed uneventfully. I had checked my equipment after start-up and it was functional. Nothing had happened but if I had looked harder before taking the runway or if he had checked his transmitter we could have avoided scaring the passenger. At least we saw and avoided before it got bad.

Narrative: TREASURE CAY ARPT (MYAT) IS A NON TWRED ARPT AND HAS NO TXWYS. AS I PREPARED FOR DEP, I DETERMINED THE WIND FAVORED RWY 14, SO I HAD TO BACK-TAXI THE LENGTH OF THE RWY. ON 122.8, THE CTAF, I ANNOUNCED 'TREASURE CAY TFC, CHIEFTAIN IS ABOUT TO BACK-TAXI. IS ANYONE INBOUND TO TREASURE CAY?' RECEIVING NO RESPONSE, I LOOKED BOTH WAYS FOR TFC AND THEN PROCEEDED ONTO THE RWY FOR MY BACK-TAXI. THE SUN WAS LOW IN THE SKY AND MADE IT DIFFICULT TO SEE TOWARD THE APCH END OF RWY 14. AS I ENTERED THE RWY, I ANNOUNCED ON CTAF 'TREASURE TFC CHIEFTAIN BACK-TAXIING FOR DEP ON RWY 14.' WHEN I COMPLETED MY TURN ONTO THE RWY, I SAW SOMETHING MOVE NEAR THE APCH END OF RWY 14 (THE FAR END OF THE RWY FROM MY POS), AND A PAX SHOUTED 'THERE'S ONE LNDG!' I IMMEDIATELY TURNED AROUND AND EXPEDITED OFF OF THE RWY WHILE ANNOUNCING ON CTAF 'CHIEFTAIN CLRING THE RWY AT TREASURE, ACFT LNDG ARE YOU ON FREQ?' AFTER I CLRED THE RWY THE OTHER PLANE LANDED AND I AGAIN ASKED IF HE WAS ON FREQ. HE RESPONDED BY SAYING 'YES I AM AND I ANSWERED EACH OF YOUR CALLS, DIDN'T YOU HEAR ME?' I TOLD HIM NO AND THAT I SUSPECTED HIS XMITTER HAD NOT BEEN WORKING. I THEN DEPARTED UNEVENTFULLY. I HAD CHKED MY EQUIP AFTER START-UP AND IT WAS FUNCTIONAL. NOTHING HAD HAPPENED BUT IF I HAD LOOKED HARDER BEFORE TAKING THE RWY OR IF HE HAD CHKED HIS XMITTER WE COULD HAVE AVOIDED SCARING THE PAX. AT LEAST WE SAW AND AVOIDED BEFORE IT GOT BAD.
