A factor associated with the accident is the reduced visibility created by the falling snow. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - On ground/water encounter with terrain/water, landing - roll - terrain condition - snow covered - terrain condition - ditch - terrain condition - soft - proper alignment - not maintained, pilot in command (cause) - weather condition - snow (contributing factor) - Nose gear collapsed, landing - flare/touchdown - landing gear,nose gear - overload ## Analysis The pilot reported he was landing on a snow covered runway in falling snow. He said the airplane touched down on the extreme left edge of the runway, and soon went off the left edge and into the adjacent snow. The airplane was pulled to the left, and the pilot was unable to return the airplane to the runway. The airplane went partially into a ditch, and sheared off the nose gear and damaged the left wing. ## Factual narrative On December 27, 1995, about 1200 Alaska standard time, a wheel equipped Cessna 337G airplane, N990LB, sustained substantial damage while landing at Stevens Village Airstrip, Stevens Village, Alaska. The airplane is owned and operated by the Lutheran Association of Missionaries. The commercial certificated pilot and the one passenger aboard were not injured. Visual meteorological conditions existed in the vicinity of the accident site, and a VFR flight was filed. The business flight departed Fairbanks, Alaska, about 1100. The pilot reported to an NTSB investigator on December 28 that he is a Lutheran Minister and was on a business flight to Stevens Village. He said the sky was obscured, and visibility was approximately one and one-half mile in falling snow. He said that he had some ice on the airplane's wings and windshield, and while landing at Stevens Village, he touched down on the extreme left edge of runway 25. The airplane's left main landing gear subsequently went off the left edge of the runway, and encountered deeper snow, which pulled the airplane further to the left. The pilot was unable to return the airplane to the runway, and the airplane went into a ditch, striking the left wing on the ground. The nose gear was also sheared off, and the belly cargo pod was torn from the fuselage. The pilot said there were no preimpact mechanical anomalies with the airplane. ## Aircraft - Registration: N990LB (not matched to a registry record) - Reported make and model: CESSNA 337G - Category: Airplane - Serial number: 33701672 - Airframe hours: 2776 - Engines: CONTINENTAL IO-360-G 210 horsepower reciprocating - Damage: Substantial damage - Flight: Business, Part 91 - Registered owner: Lutheran Missionaries - Airworthiness certificate: Standard, Normal - Last inspection: Annual, October 18, 1995, 30 hours before - Departed: FAI, FAIRBANKS, AK - Destination: SVS - Flight plan: VFR - Airport: SVS, Stevens Village, runway 25, 2,000 × 60 ft, gravel ## Flight crew As NTSB recorded them.
