C152 INSTRUCTOR AND STUDENT ENCOUNTER SKYDIVERS WHILE ENTERING THE TFC PATTERN AT 1O3.

Narrative

AS WE APCHED THE ARPT; I SAW IT BEFORE MY STUDENT. I WAS ASKING HIM QUESTIONS; PROMPTING HIM TO FIND THE ARPT BY HIMSELF. WHEN HE FINALLY DID REALIZE OUR PROX TO THE ARPT; I TOLD HIM; 'WE'D BETTER MAKE A RADIO CALL; YOU SEE WE'RE ONLY ABOUT 5 MI FROM THE ARPT; LET'S START DSNDING TOO.' HE MADE OUR FIRST RADIO CALL AT THAT POINT; ABOUT 5 MI OUT. 'LODI TFC; CESSNA XXXX IS 5 MI SE 4500 FT DSNDING; REQUEST ARPT ADVISORY; LODI.' NO ONE RESPONDED; SO WE CONTINUED TOWARD THE ARPT; AND BEGAN A STEEPER-THAN-NORMAL DSCNT SO WE COULD OVERFLY THE AIRFIELD 1000 FT ABOVE TFC PATTERN ALT; IN ORDER TO VIEW THE WINDSOCK. AS WE APCHED THE ARPT (APPROX 1 MI); I NOTICED A DHC6 TWIN OTTER VERY CLOSE TO OUR AIRPLANE; AT OUR 3 O'CLOCK POS FLYING TOWARD US. I TOOK THE CTLS FROM MY STUDENT; AND PUSHED THE NOSE DOWN TO QUICKLY DSND OUT OF THE FLT PATH OF THE AIRPLANE. I IMMEDIATELY MADE A RADIO CALL 'CESSNA XXXX WE HAVE THE TWIN OTTER IN SIGHT; ABOUT 1 MI S OF THE ARPT; DO YOU SEE US?' NO RESPONSE CAME; AND WE CONTINUED FOR ANOTHER 20 SECONDS OR SO; AT WHICH TIME WE WERE OVER THE ARPT AND WE SAW A PARACHUTE AT OUR 2 O'CLOCK POS ONLY A FEW HUNDRED YARDS AWAY. I IMMEDIATELY LOOKED ABOVE US AND ALL AROUND US FOR OTHER PARACHUTES; BUT DID NOT SEE ANY. A VOICE CAME OVER THE RADIO (THE FIRST WE HAD HEARD ON THE FREQ) AND SAID 'THE C150 OVER LODI; YOU JUST FLEW THROUGH AN ACTIVE DROP ZONE!' I SAID 'YEAH; WE JUST REALIZED THAT; I'M REALLY SORRY; WE'RE GONNA GET OUT OF HERE!' THE REPLY CAME 'IT SHOULD BE CLR ABOUT 1 MI E OF THE ARPT.' INSTEAD; WE CONTINUED TO OUR NEXT ARPT OF INTENDED LNDG; WHICH WAS NEARBY.
