# NTSB ANC97LA048: Piper PA-31-T3, N218CS, Stebbins, AK, April 7, 1997 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: April 7, 1997, 15:06 local (23:06 UTC) - Place: Stebbins, AK - Coordinates: 63.469478, -162.27919 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=63.4695&lon=-162.2792&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 7 uninjured - Status: Completed, report May 4, 1998 - Report: Approved by Office Director - NTSB office: Alaska Regional Office - NTSB case key (mKey): 2982 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ANC97LA048 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/2982/pdf - Page: https://openairdocs.org/ntsb/ANC97LA048 ## Probable cause The pilot's decision to continue VFR into IMC. Factors associated with the accident are fog/obscuration, and the pilot's failure to initiate a go-around earlier in the approach. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with terrain/water, landing - weather condition - fog (contributing factor) - weather condition - obscuration (contributing factor) - vfr flight into imc - continued, pilot in command (cause) - go-around - delayed, pilot in command (contributing factor) ## Analysis The pilot was landing at a remote village site. Reported weather was approximately 3/8 of a mile at the time of the accident. The pilot estimated the in-flight visibility as 1.5 miles, and said although much of the runway was shrouded in fog and mist, he could see the approach end of runway 05. While on a base leg to runway 05, he said he was in too close to the runway, and elected to do a tight 'S' turn to gain additional spacing. As he turned to final, he reduced engine power to idle. He subsequently realized he was too low and too slow, heard the stall warning horn, and quickly added full power. The airplane rolled to the right, and struck the runway with the right wing. ## Factual narrative On April 7, 1997, about 1506 Alaska daylight time, a wheel equipped Piper PA-31 airplane, N218CS, owned and operated by Cape Smythe Air Service, received substantial damage while landing at the Stebbins Airport, Stebbins, Alaska. None of the six passengers aboard, or the airline transport certificated pilot, reported any injuries. The 14 CFR Part 135 scheduled commuter flight, Flight 365, departed Nome, Alaska, about 1419, en route to Stebbins. A visual flight rules flight plan was in effect. The reported weather at Stebbins was characterized as instrument meteorological conditions at the time of the accident. According to witness reports, fog obscured the gravel and snow covered airstrip. The airplane was observed at a low altitude, close to the threshold of runway 05. It banked hard to the left, and right, and then collided with terrain near the runway threshold. The airplane continued down the runway a short distance, then veered off the left side of the runway and struck a snow berm. At the time of the accident, a weather observer at Stebbins estimated the visibility to be 3/8 of a mile. During a telephone conversation with the NTSB investigator-in-charge on April 17, the pilot related as he approached Stebbins, he was given a weather observation from a weather observer at Stebbins that indicated the prevailing visibility was about 1/4 mile in fog and mist. He said that was later amended to 3/8 of a mile. About seven miles from Stebbins, he said he was able to see a portion of the runway, the approach end of runway 05. The reminder of the runway and village was shrouded in fog. As he continued his approach to Stebbins, and entered a left base for runway 05, he said he realized he was in too close to the runway, performed a tight "S" turn to gain a little distance from the runway, reduced power on the turbine engines to idle, and turned final approach. During final approach, he said he was too low and too slow. He heard the stall warning horn, and quickly added full power to go-around. The airplane rolled hard to the right at the application of power, and the right wing hit the ground. In his written report to the NTSB, under the section titled: "Recommendation (how could this accident been prevented)", the pilot wrote: "Should have made a decision sooner, to go-around and get lined up with the runway." The pilot also estimated the visibility in the vicinity of the airport as 1.5 miles. ## Aircraft - Registration: [N218CS](https://openairdocs.org/deregistered/N218CS-1999-02-17), registration cancelled 1999-02-17, S/N 31T-8275016 (OpenAirDocs) - Reported make and model: Piper PA-31-T3 - Registry model: [Piper PA-31T3](https://openairdocs.org/model/piper-pa-31t3) (registry code 7103128) (OpenAirDocs) - Category: Airplane - Serial number: 31T-8275016 - Airframe hours: 9160 - Engines: P&W PT6A-11 500 horsepower turbo prop - Damage: Substantial damage - Flight: Part 135 - Registered owner: Cape Smythe Air Service - Airworthiness certificate: Standard, Normal - Last inspection: AAIP, March 12, 1997, 95 hours before - Departed: OME, NOME, AK - Destination: WBB - Flight plan: VFR - Airport: WBB, Stebbins, runway 5, 3,000 × 60 ft, gravel ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
