# NTSB SEA96LA218: Cessna 170, N2496D, Enterprise, OR, September 22, 1996 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: September 22, 1996, 11:25 local (18:25 UTC) - Place: Enterprise, OR - Coordinates: 45.720783, -117.220077 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=45.7208&lon=-117.2201&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report February 28, 1997 - Report: Approved by Office Director - NTSB case key (mKey): 42467 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA96LA218 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/42467/pdf - Page: https://openairdocs.org/ntsb/SEA96LA218 ## Probable cause the pilot's misjudgment of speed and distance during the approach/landing, his failure to attain a proper touchdown point during the landing, and his failure to go around (while there was sufficient runway remaining). The short runway was a related factor. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Nose over, landing - airport facilities,runway/landing area condition - short runway/landing area (contributing factor) - distance/speed - misjudged, pilot in command (cause) - proper touchdown point - not attained, pilot in command (cause) - go-around - not performed, pilot in command (cause) - brakes(normal) - excessive, pilot in command ## Analysis The pilot initiated a landing on a 1050 foot runway. He said the brakes locked near the end of the landing roll, and the airplane flipped over. A state policeman documented that the airplane first touched down about half way down the runway and that the wheels were locked during the entire landing roll. ## Factual narrative On September 22, 1996, about 1125 Pacific daylight time, a Cessna 170, N2496D, was substantially damaged during landing at an airstrip in Hells Canyon near Enterprise, Oregon. The flight was a 14 CFR Part 91 flight. Visual meteorological conditions prevailed at the time and no flight plan had been filed. The commercially rated pilot, who was the only occupant, was uninjured. The pilot was landing at Pittsburg Landing along the Snake river. The turf runway at the strip is 1050 feet long. The pilot stated that, due to the wind, he was landing on runway 30 that slopes slightly downhill. He said everything was normal until the brakes locked up near the end of the landing roll. A state policeman who arrived at the scene about 15 minutes after the accident stated that the first sign of touchdown was about half way down the runway and "there was no indication that the tail wheel ever touched the ground and the main gear wheels were skidding at all times where they were in contact with the ground." The officer also noted that when he arrived, the wind was blowing in a direction that would have been a tailwind for the aircraft. He also checked the main gear wheels and found that they turned freely. ## Aircraft - Registration: [N2496D](https://openairdocs.org/deregistered/N2496D-2018-03-12), registration cancelled 2018-03-12, S/N 20648, built 1952 (OpenAirDocs) - Reported make and model: Cessna 170 - Registry model: [Cessna 170B](https://openairdocs.org/model/cessna-170b) (registry code 2072306) (OpenAirDocs) - Registry engine: [Continental C145 series](https://openairdocs.org/engine/continental-c145-series) (registry code 17012, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 20648 - Airframe hours: 4100 - Engines: Continental C-145-2 145 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Prestige Motors Aircraft Sales - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 11, 1996, 45 hours before - Departed: 25U, IMNAHA, OR - Airport: Pittsburg, runway 30, 1,050 × 75 ft, grass/turf ## 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.
