| NTSB Identification: ANC98LA075. The docket is stored in the (offline) NTSB Imaging System. |
| Accident occurred Saturday, June 13, 1998 at ANCHORAGE, AK |
| Aircraft: Cessna 185, registration: N70195 |
| Injuries: 3 Minor |
| Event: 20001211X10213 Status: Final Report Approved On Thursday, February 15, 2001 |
| NTSB Preliminary Narrative (6120.19A) |
| On June 13, 1998, at 1250 Alaska daylight time, a Cessna 185 float equipped airplane, N70195, sustained substantial damage during an |
| emergency landing on mud flats about nine miles southeast of Anchorage, Alaska. The commercial pilot and the two passengers sustained |
| minor injuries. The flight was conducted under 14 CFR Part 91, as a personal flight. The flight departed from Lake Hood seaplane base in |
| Anchorage at 1150 as a local flight. Visual meteorological conditions prevailed at the time of the accident, and no flight plan was filed. |
| The pilot and both passengers stated to the NTSB investigator-in-charge (IIC) that while in cruise, returning to Anchorage, the engine lost power. |
| The pilot stated he attempted to land the airplane in water, but the airplane touched down in soft mud and nosed over. |
| An inspection of the airplane by the NTSB investigator-in-charge on June 13, disclosed the presence of fuel in both wing tanks and all fuel lines |
| to the engine. The cockpit fuel selector valve was found in the right tank position. The fuel tanks and airframe fuel lines were pressurized and |
| revealed no leaks. The flexible fuel lines between the fuel selector valve and the engine were cut open and internally inspected with no |
| abnormalities found. The engine driven fuel pump was removed and flow tested, revealing no discrepancies which would preclude engine |
| operation. |
| The engine was operated on the airframe by the NTSB IIC on June 10, 1998, and produced full power. |
| The owner reported to the NTSB IIC that about one year earlier, while in cruise flight, the engine quit. During the ensuing descent, the engine |
| was restarted, and then operated normally. The discrepancy could not be repeated, and no problems to account for the engine stoppage were |
| discovered. After the incident, the pilot had all fuel lines and both fuel cells replaced, and the engine overhauled. The engine overhaul was |
| completed 45 hours prior to the accident. |
| NTSB Final Narrative (6120.4) |
| The engine sustained a total loss of power while in cruise flight about 800 feet msl. During the forced landing on mud flats, the float equipped |
| airplane flipped over. Postaccident investigation revealed the presence of fuel in all lines, and no mechanical defects with the engine. The engine |
| operated normally when tested on the airframe. The fuel system was pressure tested, and then the flexible fuel lines were cut open for |
| inspection; these tests revealed no discrepancies. No anomalies which would prevent the engine from operating were found. |
| NTSB Probable Cause Narrative |
| The total loss of engine power for undetermined reasons. |
