# NTSB SEA93LA177: Cessna T210L, N2125S, Cheyenne, WY, August 18, 1993 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Limited investigation · Final report - Date: August 17, 1993, 19:27 local (Aug 18, 1993, 01:27 UTC) - Place: Cheyenne, WY - Coordinates: 41.139034, -104.789222 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=41.1390&lon=-104.7892&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 2 serious - Status: Completed, report August 1, 1994 - Report: Approved by Office Director - NTSB case key (mKey): 41750 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA93LA177 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/41750/pdf - Page: https://openairdocs.org/ntsb/SEA93LA177 ## Probable cause AN UNDETERMINED LOSS OF ENGINE POWER. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, approach - vfr pattern - final approach - reason for occurrence undetermined (cause) - Forced landing, descent - emergency - On ground/water encounter with terrain/water, landing - roll - terrain condition - ditch ## Analysis WHILE ON FINAL APPROACH FOR LANDING, THE ENGINE SUDDENLY LOST POWER. THE FLIGHT WAS UNABLE TO REACH THE RUNWAY, THEREFORE, THE PILOT OPTED TO MAKE A TURN AND LAND IN AN OPEN FIELD. DURING THE LANDING ROLL, THE AIRPLANE COLLIDED WITH A DITCH AND THE AIRPORT BOUNDARY FENCE. DURING A POST CRASH INSPECTION OF THE ENGINE, THERE WAS NO EVIDENCE FOUND TO INDICATE A MECHANICAL FAILURE OR MALFUNCTION. ## Factual narrative On August 17, 1993, at 1927 hours mountain daylight time, a Cessna T210L, N2125S, experienced a loss of engine power while on final approach to the Cheyenne Airport, Cheyenne, Wyoming. The flight was unable to make it to the runway and a forced landing was made to a field. During the landing roll, the airplane collided with a ditch and airport boundary fence. Visual meteorological conditions prevailed at the time and a visual flight rules flight plan was filed. The airplane was substantially damaged and the certificated airline transport pilot and pilot rated passenger were seriously injured. The flight had originated from Denver, Colorado, on August 17, 1993, at approximately 1845, as a pleasure flight. During a telephone interview and subsequent written statement, the pilot reported that when approximately five miles south of the airport, he completed the before landing checklist. The check consisted of switching the fuel selector to the right fuel tank, extending the landing gear, and adjusting the engine controls. The flight then entered the downwind leg for runway 12. Everything was normal until turning to final approach, when the engine quit. The pilot was unable to restart the engine and an emergency forced landing was made to a field. In the pilot's written statement, he reported that during the preflight check, water was present when drained from the right wing tank. The pilot stated that the fuel was drained sufficiently to ensure that no more water was present. The pilot also drained fuel from the two sump drains located under the fuselage and the engine compartment drain. The pilot did not mention the detection of water in any other area. During an engine inspection, it was found that the engine rotated easily with normal range compression developed in each cylinder. Rocker arm, valve train and accessory gear continuity was established. All spark plugs displayed normal operating signatures, and both magnetos sparked in firing sequence when rotated. Fuel was removed from the right header tank and the gascolator in the fuselage to check for contaminants. There were no noted contaminants found. ## Aircraft - Registration: [N2125S](https://openairdocs.org/deregistered/N2125S-2013-07-15), registration cancelled 2013-07-15, S/N 21061087, built 1975 (OpenAirDocs) - Reported make and model: CESSNA T210L - Registry model: [Cessna T210L](https://openairdocs.org/model/cessna-t210l) (registry code 2073449) (OpenAirDocs) - Registry engine: [Continental TSIO-520 series](https://openairdocs.org/engine/continental-tsio-520-series) (registry code 17040, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 21061087 - Airframe hours: 4097 - Engines: CONTINENTAL TSIO-520-H4A 310 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Wings Of Denver - Registered owner: Precision Aircraft - Airworthiness certificate: Standard, Normal - Last inspection: Annual, July 22, 1993, 19 hours before - Departed: APA, DENVER, CO - Flight plan: VFR ## Flight crew As NTSB recorded them.

Lost power on approach. Landed open field. Hit a ditch and fence. No engine problems found. From the NTSB's public API. 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
