# NTSB DEN99TA099: Cessna A185F, N4211C, Farmington, NM, June 10, 1999 - Type: NTSB accident investigation - Classification: Accident · No injuries · Final report - Date: June 10, 1999, 14:14 local (20:14 UTC) - Place: Farmington, NM - Coordinates: 36.749233, -108.179534 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=36.7492&lon=-108.1795&mi=10 - Phase of flight: [Initial climb](https://openairdocs.org/ntsb-phases/350) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report April 25, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 46491 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DEN99TA099 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/46491/pdf - Page: https://openairdocs.org/ntsb/DEN99TA099 ## Probable cause The pilot's inadequate visual lookout and failure to see and avoid a ground obstruction. Factors were the throttle linkage becoming disconnected due to an inadequate annual inspection by maintenance personnel, and a dirt berm. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(partial) - nonmechanical, takeoff - initial climb - throttle/power lever,linkage - disconnected (contributing factor) - maintenance,annual inspection - inadequate, other maintenance personnel (contributing factor) - Forced landing, descent - emergency - terrain condition - open field - In flight collision with terrain/water, takeoff - roll/run - terrain condition - berm (contributing factor) - landing gear,main gear strut - sheared - visual lookout - inadequate, pilot in command (cause) - Forced landing, descent - emergency - airport facilities,runway/landing area condition - runway - Dragged wing,rotor,pod,float or tail/skid, landing - roll ## Analysis Shortly after takeoff, engine power dropped to idle. The pilot made a forced landing in a field 3 miles north of the airport. A mechanic from the airport examined the engine and discovered the throttle cable had become disconnected from the throttle linkage due to looseness of the nut and bolt. While the mechanic made the necessary repairs, the pilot examined the field and determined he had sufficient clearance for take off. After repairs were made, the pilot attempted to take off. As the airplane lifted off, the left main landing gear struck a mound of dirt. The impact sheared the mounting bolt and the left main landing gear fell off the airplane. The pilot flew back to the airport and landed with the airplane coming to rest on its left wing tip. ## Factual narrative On June 10, 1999, at 1414 mountain daylight time, a Cessna A185F, N4211C, owned and operated by the State of Colorado's Division of Wildlife, was substantially damaged during takeoff near Farmington, New Mexico. The airline transport certificated pilot, the sole occupant aboard, was not injured. Visual meteorological conditions prevailed, and no flight plan had been filed for the public use flight being conducted under Title 14 CFR Part 91. The flight was originating at the time of the accident. According to the pilot, he took off from Four Corners Regional Airport, Farmington, New Mexico, en route to Creede, Colorado. Shortly after departure, at an altitude of 600 feet agl, engine power dropped to idle. The pilot made a forced landing in a field 3 miles north of the airport. The time was approximately 1315. A mechanic from the airport examined the engine and discovered the throttle cable had become disconnected from the throttle linkage due to looseness of the nut and bolt. While the mechanic made the necessary repairs, the pilot examined the field and determined he had sufficient clearance for take off. After repairs were made, the pilot attempted to take off. As the airplane lifted off, the left main landing gear struck a mound of dirt. The impact sheared the mounting bolt and the left main landing gear fell off the airplane. The pilot flew to Four Corners Regional Airport, made a low pass, then landed on runway 11 at 1420. The airplane skidded to a halt, coming to rest on its left wing tip. ## Aircraft - Registration: [N4211C](https://openairdocs.org/aircraft/N4211C), registered now, S/N 18503823, built 1979 (OpenAirDocs) - Reported make and model: Cessna A185F - Registry model: [Cessna A185F](https://openairdocs.org/model/cessna-a185f) (registry code 2072821) (OpenAirDocs) - Registry engine: [Continental IO-520-D](https://openairdocs.org/engine/continental-io-520-d) (registry code 17236, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18503823 - Airframe hours: 5389 - Engines: Continental IO-520-040B 300 horsepower reciprocating - Damage: Substantial damage - Flight: Public aircraft, Part 91 - Registered owner: Colorado Division Of Wildlife - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 2, 1999, 27 hours before - Departed: FMN, FARMINGTON, NM - Destination: Q39, CREEDE, CO - Flight plan: Company VFR - Airport: FMN, Four Corners Regional, runway 11, 2,783 × 100 ft, dirt ## 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.
