# NTSB CHI05LA129: Cessna 210B, N9623X, Friendship, WI, May 30, 2005 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: May 29, 2005, 22:00 local (May 30, 2005, 03:00 UTC) - Place: Friendship, WI - Coordinates: 43.968612, -89.802223 - Nearby events: https://openairdocs.org/map.md?lat=43.9686&lon=-89.8022&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report March 28, 2006 - Report: Approved by Office Director - Parties: Federal Aviation Administration - Milwaukee FSDO - NTSB case key (mKey): 61784 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI05LA129 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/61784/pdf - Page: https://openairdocs.org/ntsb/CHI05LA129 ## Probable cause The loss of engine power for an undetermined reason. Contributing factors to the accident were the trees and the dark night light condition. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, go-around (vfr) - reason for occurrence undetermined (cause) - Forced landing, emergency descent/landing - In flight collision with object, emergency descent/landing - light condition - dark night (contributing factor) - object - tree(s) (contributing factor) - In flight collision with terrain/water, descent - uncontrolled - terrain condition - ground ## Analysis The airplane impacted trees and terrain during a forced landing at night following a loss of engine power. The pilot reported that when the airplane crossed the approach end of the runway he initiated a go-around because the airplane was a "little high." The pilot stated that he "visually confirmed mixture and prop controls were full forward, smoothly applied full throttle, and pitched for [a] level flight attitude." The pilot reported that engine power momentarily increased but was "quickly followed by abnormal noises and [a] loss of power." The pilot stated that the airplane was "too far down the runway" to land on the remaining pavement and an off-airport forced landing was performed. The airplane came to rest along the extended runway centerline in a forested area, approximately 1,007 feet from the departure end of the runway. After the accident, 14 gallons of fuel were recovered from the left fuel tank and 8 gallons were recovered from the right fuel tank. The engine did not experience any hesitation, stumbling, or interruption in engine operation during an engine test run. The engine demonstrated the ability to produce rated horsepower. ## Factual narrative On May 29, 2005, at 2200 central daylight time, a Cessna 210B, N9623X, owned and piloted by a commercial pilot, was substantially damaged during a forced landing near Adams County Airport, Friendship, Wisconsin. The pilot was attempting a go-around from runway 33 (3,400 feet by 60 feet, asphalt) when the aircraft experienced a loss of engine power. Night visual meteorological conditions prevailed at the time of the accident. The personal flight was operating under the provisions of 14 Code of Federal Regulations (CFR) Part 91 without a flight plan. The pilot and his passenger were not injured. The flight originated from Warren County Regional Airport, Bowling Green, Kentucky, at 1800. The pilot reported that when the airplane crossed the approach end of runway 33 he initiated a go-around because the airplane was a "little high." The pilot stated that he "visually confirmed mixture and prop controls were full forward, smoothly applied full throttle, and pitched for [a] level flight attitude." The pilot reported that engine power momentarily increased but was "quickly followed by abnormal noises and [a] loss of power." The pilot stated that the airplane was "too far down the runway" to land on the remaining pavement and an off-airport forced landing was performed. The airplane came to rest along the extended runway centerline in a forested area, approximately 1,000 feet from the departure end of the runway. After the accident, a salvage company drained the airplane's fuel system to facilitate movement of the wreckage. The salvage company reported that 14 gallons of fuel were drained from the left fuel tank and 8 gallons were drained from the right fuel tank. The engine, a Teledyne Continental Motors IO-470-S, was sent to the manufacturer for an operational test run under the supervision of the NTSB investigator-in-charge. The engine was installed in a test cell and outfitted with a test club propeller. The engine started on the first attempt and idled without excessive fluctuations in engine RPM. The engine speed was increased incrementally to 2,625 RPM over a period of 30 minutes. The engine ran at each incremental power setting for a period of 5 minutes without anomaly. The engine throttle was cycled several times between idle and maximum power settings in quick succession. The engine did not experience any hesitation, stumbling, or interruption in engine operation during the engine test run. The engine demonstrated the ability to produce rated horsepower. ## Aircraft - Registration: [N9623X](https://openairdocs.org/deregistered/N9623X-2011-01-07), registration cancelled 2011-01-07, S/N 21057923, built 1962 (OpenAirDocs) - Reported make and model: Cessna 210B - Registry model: [Cessna 210B](https://openairdocs.org/model/cessna-210b) (registry code 2073410) (OpenAirDocs) - Registry engine: [Continental I0-470 series](https://openairdocs.org/engine/continental-i0-470-series) (registry code 17027, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 21057923 - Airframe hours: 3378.26 - Engines: Teledyne Continental IO-470-S 260 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 1, 2004, 140.05 hours before - Departed: BWG, Bowling Green, KY - Destination: 63C, Friendship, WI - Airport: 63C, Adams County Airport, runway 33, 3,400 × 60 ft, asphalt ## Flight crew As NTSB recorded them.
