STUDENT PLT OF SMA BECAME HESITANT TO LAND DUE TO TURB IN THE TFC PATTERN. HE FLEW SEVERAL TIMES AROUND THE PATTERN BEFORE A FLT INSTRUCTOR TALKED HIM THROUGH A LNDG. THE TWR CTLR DECLARED AN EMER IN ORDER TO SEPARATE OTHER TFC FROM THE STUDENT'S INTENDED FLT PATH.

Narrative

A STUDENT FROM MY FBO CAME TO ME AND SAID HE NEEDED MORE SOLO TIME TO COMPLETE THE REQUIRED 5 HRS OF SOLO SPELLED OUT BY OUR PART 141 PVT PLT CURRICULUM. I WAS NOT HIS USUAL INSTRUCTOR; BUT I HAD FLOWN WITH HIM BEFORE. I ENDORSED HIS LOGBOOK FOR 90 DAY CURRENCY REQUIREMENTS WHICH HAD LAPSED. I CHKED THE WX AND EVERYTHING SEEMED TO BE WITHIN HIS SIGNOFF LIMITS OF 10 KTS WIND AND 6 KTS XWIND. WINDS WRE 330 DEGS AT 7 KTS AND HE WOULD BE USING RWY 36. RWY 32/14 AND RWY 4/22 WERE CLOSED. THE STUDENT HAD 3 HRS PREVIOUS EXPERIENCE SOLO AND HAD COMPLETED HIS SOLO XCOUNTRY. STUDENT TOOK OFF RWY 36 AROUND XA45 AND AROUND XB00 I RECEIVED A CALL FROM THE TWR TELLING ME THAT THE STUDENT WAS HAVING PROBS IN THE PATTERN AND HAD MADE 3 UNSUCCESSFUL ATTEMPTS AT LNDG. IT WAS REQUESTED THAT I COME UP TO THE TWR. ANOTHER INSTRUCTOR AND I WENT UP TO THE TWR TO GET A BETTER VIEW OF WHAT WAS HAPPENING. THE STUDENT WAS FLYING 1100 FT PATTERNS AT A 1500 FT TPA ARPT. THE STUDENT MADE 1 MORE ATTEMPT AT LNDG AND WAS UNSUCCESSFUL. AT THAT POINT THE TWR CTLRS DECLARED AN EMER AND ROLLED THE FIRE RESCUE TRUCKS OUT TO THE RWY. THE STUDENT WAS ABLE TO LAND THE AIRPLANE AFTER THE FIFTH ATTEMPT AND NO HARM WAS DONE TO THE PLT OR AIRPLANE. AFTER THE STUDENT PARKED THE ACFT HE WAS VISIBLY SHAKEN AND EXPLAINED THAT HE HAD NEVER FLOWN IN SUCH 'BUMPY' WX. THE STUDENT WORKED 8-5 EVERYDAY AND HAD VERY FEW HRS OF MIDDAY FLYING. AFTER THE INCIDENT; I WENT BACK INTO THE AIR TO SEE HOW BUMPY IT WAS. THERE WAS LIGHT CHOP EXPERIENCED THROUGHOUT THE PATTERN AND THE WINDS WERE SLIGHTLY GUSTY. NOTHING MY STUDENTS IN THE PAST HAVE HAD PROBS WITH. CONCLUSION: I SHOULD HAVE GONE UP WITH THE STUDENT FIRST TO SEE IF HE COULD HANDLE THE TURBULENT CONDITIONS.
