Narrative:

On jan/xx/96 a flight from fmn to lar was attempted with 1 passenger and 1 pilot. The aircraft was fully serviced, WX checked VFR, and a thorough preflight performed by the pilot. Fuel quantity was checked both visually and on the gauges by the pilot and a lineman. The fuel tanks holding 88 gallons of usable fuel would be more than required and needed. The flight track varied from planned due to WX and the ETA was extended. WX information was also updated. WX prevented flight within 30 NM of lar and also from accepting an IFR clearance due to icing. Many possible alternate fields were not available due to snow covered runways and unforecast poor WX. Hdn was selected as the best and next alternate. On final approach, at 200 to 300 ft AGL, a power loss occurred. Emergency procedures were completed with no positive results. Touchdown was on the extended centerline of runway 28, 150 yards from the approach end. The aircraft remained intact and undamaged except for the nose gear and bent propeller blades. No injuries were incurred. A post flight inspection by both the pilot and passenger (an aircraft mechanic) revealed there was still fuel remaining in both tanks. Later inspections throughout the day revealed less and less fuel. Upon removal of the aircraft from the snow, blue fuel stains were noticed. Total flight time was 3.5 hours. The cause of the engine failure is under investigation. Problems encountered in flight were unforecast WX, poor NAVAID reception, and difficulty/delays with FSS's and center. The NTSB has ruled this an incident. At this time, feb/xx/96, the aircraft is still on the ramp at hdn. WX (heavy snow) has prevented further inspection. Callback conversation with reporter revealed the following information: reporter states that it was about 2 weeks before mechanics were able to drain the tanks and determine that there was at least half of the fuel remaining. There is still no real determination of the actual problem since the engine checked out ok. It is suspected that there was ice crystal blockage of the intake port. This aircraft has a robertson STOL kit with high lift capability. The confign of nose low attitude with 40 degrees of flap would allow for such blockage, according to the company experts with whom reporter has conferred. Aircraft is a C206.

Title: CHARTER FLT HAS ENG QUIT ON APCH. OFF ARPT LNDG.

Narrative: ON JAN/XX/96 A FLT FROM FMN TO LAR WAS ATTEMPTED WITH 1 PAX AND 1 PLT. THE ACFT WAS FULLY SERVICED, WX CHKED VFR, AND A THOROUGH PREFLT PERFORMED BY THE PLT. FUEL QUANTITY WAS CHKED BOTH VISUALLY AND ON THE GAUGES BY THE PLT AND A LINEMAN. THE FUEL TANKS HOLDING 88 GALLONS OF USABLE FUEL WOULD BE MORE THAN REQUIRED AND NEEDED. THE FLT TRACK VARIED FROM PLANNED DUE TO WX AND THE ETA WAS EXTENDED. WX INFO WAS ALSO UPDATED. WX PREVENTED FLT WITHIN 30 NM OF LAR AND ALSO FROM ACCEPTING AN IFR CLRNC DUE TO ICING. MANY POSSIBLE ALTERNATE FIELDS WERE NOT AVAILABLE DUE TO SNOW COVERED RWYS AND UNFORECAST POOR WX. HDN WAS SELECTED AS THE BEST AND NEXT ALTERNATE. ON FINAL APCH, AT 200 TO 300 FT AGL, A PWR LOSS OCCURRED. EMER PROCS WERE COMPLETED WITH NO POSITIVE RESULTS. TOUCHDOWN WAS ON THE EXTENDED CTRLINE OF RWY 28, 150 YARDS FROM THE APCH END. THE ACFT REMAINED INTACT AND UNDAMAGED EXCEPT FOR THE NOSE GEAR AND BENT PROP BLADES. NO INJURIES WERE INCURRED. A POST FLT INSPECTION BY BOTH THE PLT AND PAX (AN ACFT MECH) REVEALED THERE WAS STILL FUEL REMAINING IN BOTH TANKS. LATER INSPECTIONS THROUGHOUT THE DAY REVEALED LESS AND LESS FUEL. UPON REMOVAL OF THE ACFT FROM THE SNOW, BLUE FUEL STAINS WERE NOTICED. TOTAL FLT TIME WAS 3.5 HRS. THE CAUSE OF THE ENG FAILURE IS UNDER INVESTIGATION. PROBS ENCOUNTERED IN FLT WERE UNFORECAST WX, POOR NAVAID RECEPTION, AND DIFFICULTY/DELAYS WITH FSS'S AND CTR. THE NTSB HAS RULED THIS AN INCIDENT. AT THIS TIME, FEB/XX/96, THE ACFT IS STILL ON THE RAMP AT HDN. WX (HVY SNOW) HAS PREVENTED FURTHER INSPECTION. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES THAT IT WAS ABOUT 2 WKS BEFORE MECHS WERE ABLE TO DRAIN THE TANKS AND DETERMINE THAT THERE WAS AT LEAST HALF OF THE FUEL REMAINING. THERE IS STILL NO REAL DETERMINATION OF THE ACTUAL PROB SINCE THE ENG CHKED OUT OK. IT IS SUSPECTED THAT THERE WAS ICE CRYSTAL BLOCKAGE OF THE INTAKE PORT. THIS ACFT HAS A ROBERTSON STOL KIT WITH HIGH LIFT CAPABILITY. THE CONFIGN OF NOSE LOW ATTITUDE WITH 40 DEGS OF FLAP WOULD ALLOW FOR SUCH BLOCKAGE, ACCORDING TO THE COMPANY EXPERTS WITH WHOM RPTR HAS CONFERRED. ACFT IS A C206.
