# NTSB DEN08LA014: Cessna 210, N215MD, Canon City, CO, October 17, 2007 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: October 17, 2007, 15:15 local (21:15 UTC) - Place: Canon City, CO - Coordinates: 38.42361, -105.103614 - Nearby events: https://openairdocs.org/map.md?lat=38.4236&lon=-105.1036&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report April 30, 2008 - Report: Approved by Office Director - Parties: Teledyne Continental Motors, Cessna Aircraft Company, Federal Aviation Administration - NTSB case key (mKey): 66954 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DEN08LA014 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/66954/pdf - Page: https://openairdocs.org/ntsb/DEN08LA014 ## Probable cause The failure of the engine throttle cable resulting in a lack of engine power when commanded. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(partial) - mech failure/malf, approach - vfr pattern - final approach - proper glidepath - not maintained, dual student - throttle/power control - not possible, dual student (cause) - throttle/power lever,cable - failure (cause) - Forced landing, emergency descent/landing - On ground/water encounter with terrain/water, emergency landing - terrain condition - open field - terrain condition - none suitable ## Analysis On final approach during the fourth landing the instructor noticed they had descended below the glideslope. When the student advanced the throttle to climb back onto the glideslope there was no response from the engine. The student pumped the throttle and turned on the electric fuel pump without result. The airplane landed in a dirt field, approximately 200 feet short of the runway. The nose landing gear collapsed and the airframe sustained substantial damage. Examination of the airplane revealed the throttle cable was broken, and several areas of the cable showed signs of wear. A broken throttle cable may prevent application of power when commanded. An examination of the remaining airplane systems revealed no anomalies. ## Factual narrative On October 17, 2007, approximately 1515 mountain daylight time, a Cessna 210, N215MD, was substantially damaged when it impacted terrain following a loss of engine power while on final approach to Fremont County Airport (1V6), Canon City, Colorado. Visual meteorological conditions prevailed at the time of the accident. The instructional flight was being conducted under the provisions of Title 14 Code of Federal Regulations Part 91 without a flight plan. The flight instructor and private pilot receiving instruction were not injured. The local flight originated at 1400. According to the flight instructor's statement, he and the student had completed their maneuvers and returned to the airport for a series of touch-and-go landings, in partial completion of a flight review. While on final approach for the fourth landing, the instructor noticed they had descended below the glideslope on the Visual Approach Slope Indicator (VASI). The student advanced the throttle to climb back onto the glideslope and there was no response from the engine. The student pumped the throttle and turned on the electric fuel pump without result. The airplane landed in a dirt field approximately 200 feet short of the runway. Examination of the airplane revealed the nose gear collapsed and the frame cross beam on the right side was cracked. An examination of the airplane engine by the Safety Board Investigator-in-charge and a representative from Teledyne Continental Motors revealed that the engine throttle cable rod had broken. Further examination of the throttle cable assembly, conducted by Cessna Aircraft Company under the auspices of the Federal Aviation Administration, revealed the throttle cable outer sleeve was cracked and had separated from the steel fitting. The end of the steel fitting was worn and deformed, and the swivel ball fitting at the end of the plunger was worn. The throttle cable was not a Cessna provided part. A placard on the throttle cable identified it as originating from Aircraft Components Inc. (ACI) of Benton Harbor, Michigan. ACI was a mail-order aircraft parts supplier, and ceased operations in 1990. Cessna recommends that all engine control cables be replaced at engine overhaul. A review of the maintenance records revealed the last engine overhaul was completed on November 2, 1989. The last annual inspection was competed on October 2, 2007. There was no entry in the maintenance records reflecting when the engine control cables were last replaced. ## Aircraft - Registration: [N215MD](https://openairdocs.org/deregistered/N215MD-2021-11-18), registration cancelled 2021-11-18, S/N 57210 (OpenAirDocs) - Reported make and model: Cessna 210 - Registry model: [Cessna 210](https://openairdocs.org/model/cessna-210) (registry code 2073402) (OpenAirDocs) - Registry engine: [Continental I0-470 series](https://openairdocs.org/engine/continental-i0-470-series) (registry code 17027, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 57210 - Airframe hours: 2758 - Engines: Continental IO470E 260 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Carroll G.
