A JUMP MASTER IN C172 INTERFERES WITH THE PLT AND INCREASES THE ANGLE OF BANK TO MAKE A DELAYING 360 DEG TURN PRIOR TO THE FINAL JUMP RUN.

Narrative

I WAS ACTING AS JUMP MASTER FOR AN OPENING ACT AT AN EVENT. WE DEPARTED IN THE C172 WITH ITS R-HAND DOOR REMOVED FOR SKYDIVING. THE PIC'S PROCS DURING THE TKOF; TFC PATTERN DEP; AND THE SUBSEQUENT WIND INDICATOR DROP ALL SEEMED TO BE NORMAL FOR A JUMP PLT'S OP (BANK ANGLES OF 30 DEGS L AND R). I DIRECTED THE PIC TO MOVE CLOSER TO SPOT CLOSER DOWNWIND OF OUR FINAL 'JUMP RUN' WHICH HE ACCOMPLISHED WITH NO CONCERN ON MY PART. THE PIC STARTED THE 'FINAL JUMP RUN' AND I COULD SEE THAT WE WERE GOING TO BE APPROX 1 MIN EARLY FOR THE SHOW ANNOUNCER AND START OF AIR SHOW; SO I ASKED THE PIC FOR A 360 DEG TURN AND HE GAVE ME APPROX A 15 DEG BANK TO THE R. I ASKED HIM TO INCREASE THE RATE OF TURN. HE DID NOTHING; HE SAID NOTHING; SO I PUT MY L HAND ON THE OUTBOARD PORTION OF L CTL AND INCREASED THE BANK ANGLE TO APPROX 30-40 DEGS OF BANK UNTIL I ROLLED THE ACFT OUT ON THE 'FINAL JUMP RUN' HDG. DURING THAT PERIOD OF TIME; THE PIC GAVE ME NO EXPRESSION OF CONCERN -- EITHER AURAL OR TACTILE! WE JUMPED AND I GAVE IT NO FURTHER THOUGHT. LATER; THE PIC CALLED THE OPERATOR; WHO CONFRONTED ME WITH THEIR CONCERNS OVER MY EXCEEDING THE 15 DEG BANK PER THE 'DOOR REMOVED LIMITATIONS.' CONTRIBUTING FACTORS: OPERATOR HAD VERBALLY COMMITTED TO C206 ACFT SEVERAL MONTHS PRIOR TO AIRSHOW THEN 2 WKS PRIOR TO SHOW HE CALLS AND SAYS THAT HE CAN ONLY GET A C182. THE DAY BEFORE THE SHOW (PRESS SHOW) THE OPERATOR ONLY HAS A C172 BUT PROMISES A C182 FOR THE NEXT DAY. THE DAY OF THE AIRSHOW AND THE SIT THE OPERATOR ONLY HAD A C172. SO BY NOW MY PATIENCE WITH THESE FOLKS IS AT MINIMUM POINT -- WHICH LED TO THE NEXT FACTOR: COM WITH THE PIC WITH EMPHASIS ON SPECIAL EVENT NEEDS.
