Narrative:

Event occurred at F45 (north county general aviation airport). I was giving instruction to a student pilot with approximately 6 hours total time; all dual. We were making a normal approach to landing on runway 13. We had broadcast on CTAF while on crosswind; downwind; base and final. As we were approximately 35 ft over the approach end of the runway; a small experimental took off from runway 26R. Had both aircraft not maneuvered to avoid; there would have been a collision. After landing; the pilot of the experimental aircraft approached me on the ramp. He was very apologetic and aware of his mistake. He stated that he did not have a radio in his airplane and he thought he had looked; but obviously he had missed seeing us. He was adamant that he would not let this mistake happen again. Contributing factors: 1) the sun was very bright in the eyes of the pilots in the C172; making it difficult to see the experimental aircraft. 2) the experimental aircraft did not have an operating 2-WAY radio; and did not clear all sectors prior to takeoff. 3) F45 is a non-twred field despite a heavy training and corporate use traffic load.

Title: A C172 EXPERIENCED AN NMAC WITH AN EXPERIMENTAL AT UNCTLED FIELD F45.

Narrative: EVENT OCCURRED AT F45 (NORTH COUNTY GENERAL AVIATION ARPT). I WAS GIVING INSTRUCTION TO A STUDENT PLT WITH APPROX 6 HRS TOTAL TIME; ALL DUAL. WE WERE MAKING A NORMAL APCH TO LNDG ON RWY 13. WE HAD BROADCAST ON CTAF WHILE ON XWIND; DOWNWIND; BASE AND FINAL. AS WE WERE APPROX 35 FT OVER THE APCH END OF THE RWY; A SMALL EXPERIMENTAL TOOK OFF FROM RWY 26R. HAD BOTH ACFT NOT MANEUVERED TO AVOID; THERE WOULD HAVE BEEN A COLLISION. AFTER LNDG; THE PLT OF THE EXPERIMENTAL ACFT APPROACHED ME ON THE RAMP. HE WAS VERY APOLOGETIC AND AWARE OF HIS MISTAKE. HE STATED THAT HE DID NOT HAVE A RADIO IN HIS AIRPLANE AND HE THOUGHT HE HAD LOOKED; BUT OBVIOUSLY HE HAD MISSED SEEING US. HE WAS ADAMANT THAT HE WOULD NOT LET THIS MISTAKE HAPPEN AGAIN. CONTRIBUTING FACTORS: 1) THE SUN WAS VERY BRIGHT IN THE EYES OF THE PLTS IN THE C172; MAKING IT DIFFICULT TO SEE THE EXPERIMENTAL ACFT. 2) THE EXPERIMENTAL ACFT DID NOT HAVE AN OPERATING 2-WAY RADIO; AND DID NOT CLR ALL SECTORS PRIOR TO TAKEOFF. 3) F45 IS A NON-TWRED FIELD DESPITE A HVY TRAINING AND CORPORATE USE TFC LOAD.
