JUMP PLT MAKES DSNDING SPIRAL APCH TO LAND AT UNCTLED ARPT.

Narrative

AFTER DROPPING A LOAD OF JUMPERS; I MADE AN OVERHEAD APCH TO RWY 1. STARTING AT APPROX 4000 FT AGL OVERHEAD THE ARPT; I REDUCED THE PWR TO IDLE; ANNOUNCED ON THE UNICOM FREQ MY INTENTION TO MAKE AN OVERHEAD APCH; AND SCANNED FOR TFC. I CONTINUED TO SCAN FOR TFC AND MONITOR THE RADIO; AND MANEUVERED THE AIRPLANE IN A L SPIRAL TO ARRIVE AT THE FOLLOWING POINT TO BEGIN MY FINAL LNDG APCH. ALT: 800 FT AGL; AIRSPD: 80 MPH (NOT KTS) INDICATED; POS: OVER THE APCH END OF THE RWY; HDG: RWY HDG (APPROX 010). PWR: IDLE. ONCE I ARRIVED AT THIS POINT; I MADE A CONTINUOUS L TURN; BANKING UP TO 30 TO 45 DEGS AS NECESSARY; AND LANDED ON THE RWY. I SAW NO TFC AS I DSNDED IN MY SPIRAL; AND THERE WAS NO TFC IN TFC PATTERN. FLYING FOR SKYDIVERS GREATLY INCREASE THE LIKELIHOOD OF ENG FAILURE BECAUSE OF FREQUENT FULL-PWR CLBS FOLLOWED BY RAPID; REDUCED-PWR DSCNTS. EVEN THOUGH I DO WHAT I CAN TO MINIMIZE STRESS ON THE AIRFRAME AND ENG; I FEEL I AM SAFER IF I CAN PRACTICE EMER PROCS; INCLUDING PWR-OFF APCHS AND LNDGS. I TRY TO MAKE AT LEAST 1 SUCH APCH AND LNDG SUCCESSFULLY EACH DAY I DROP JUMPERS. THE ARPT MGR AT GARNETT ASKED ME THAT DAY NOT TO PRACTICE SUCH LNDGS. I POINTED OUT THAT I HAD FLOWN A LEGAL PATTERN; THAT I HAD TAKEN PRECAUTIONS TO FLY THE MANEUVER SAFELY; THAT THERE WAS NO TFC CONFLICT; AND THAT SAFETY REQUIRED ME TO PRACTICE. FURTHER; I HAD BEEN MAKING OVERHEAD APCHS AT LEAST ONCE EACH DAY I FLEW (NEARLY EVERY WEEKEND FOR SEVERAL YRS) WITHOUT HIS OBJECTION. CLRLY; I DID NOT FLY THE TFC PATTERN DEPICTED IN THE FIGURE 4-54(1) OF THE AIRMAN'S INFO MANUAL. PERHAPS THERE NEEDS TO BE AN EXPLICIT STATEMENT IN FAR 91.127(B)(1) WHICH WILL ALLOW NON-STANDARD PATTERNS FOR TRAINING. (AS AN ADDITIONAL THOUGHT: FAR 91.127(B)(1) MAKES IT ILLEGAL AT MOST ARPTS TO FLY THE R-HAND PATTERN REQUIRED BY MOST CRITICAL ENG FAILURES IN MULTI-ENG ACFT).
