# NTSB FTW01LA082: Champion 7KCAB, N9017L, Ragley, LA, March 17, 2001 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Limited investigation · Final report - Date: March 17, 2001, 08:45 local (14:45 UTC) - Place: Ragley, LA - Coordinates: 30.509109, -93.230018 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=30.5091&lon=-93.2300&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 1 serious - Status: Completed, report July 30, 2001 - Report: Approved by Office Director - Parties: FAA - NTSB case key (mKey): 51966 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=FTW01LA082 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/51966/pdf - Page: https://openairdocs.org/ntsb/FTW01LA082 ## Probable cause the loose clamp (Nicopress fitting) on the elevator control cable due to inadequate quality control during the cable's manufacturing, which allowed the cable to disconnect and restricted the pilot's control of the airplane during landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Airframe/component/system failure/malfunction, maneuvering - flt control syst,elevator control cable/rod - loose part/bolt/nut/clamp/etc (cause) - inadequate quality control, other person (cause) - flt control syst,elevator control cable/rod - disconnected (cause) - Forced landing, emergency descent/landing - Hard landing, emergency descent/landing - aircraft control - restricted, pilot in command (cause) ## Analysis According to the pilot, after about 15 minutes of flight, the airplane was in a turn and descending slightly, when "the stick suddenly snapped back with no pressure on it." The nose immediately "ducked down" and the pilot "pulled" the trim back to raise the nose while leveling the wings. After leveling off, the pilot started back to his airstrip. On short final, he noticed that he did not have enough time and distance to achieve a steady descent with only trim tabs to control the pitch. After a "go-around", the pilot attempted to set up for a shallow approach. About 75 to 100 feet above the ground on final, the pilot felt "turbulence" and the airplane began descending quickly. The airplane then impacted the ground "pretty hard" breaking the left landing gear, skidding about 40 feet, and coming to rest in an upright position. Examination of the airplane after the accident revealed that the elevator control cable was found liberated from its "Nicopress" fitting. The elevator cable had been replaced with a new cable by the pilot, under the supervision of a A&P mechanic on February 8, 2001. According to the pilot, the new elevator cable was fabricated for him by an aircraft maintenance facility. The airplane was given an annual inspection on March 6, 2001 by the same A&P mechanic who assisted with the elevator cable installation. The last time the airplane flew prior to the accident was on March 8, 2001, when the pilot flew the airplane for about 35 minutes with no anomalies. ## Factual narrative On March 17, 2001, approximately 0845 central standard time, a Champion 7KCAB airplane, N9017L, registered to and operated by the pilot, was substantially damaged during a forced landing following an elevator flight control malfunction while maneuvering in the vicinity of Ragley, Louisiana. The commercial pilot, who was the sole occupant, sustained serious injuries. Visual meteorological conditions prevailed and a flight plan was not filed for the 14 Code of Federal Regulations Part 91 personal flight. The flight originated at 0830 from a private grass airstrip located in Ragley. The pilot reported that he was flying locally, near his home looking at some fields and reforested pine trees. After about 15 minutes of flight, he was in a turn and descending slightly, when "the stick suddenly snapped back with no pressure on it." The nose immediately "ducked down" and the pilot "pulled" the trim back to raise the nose while leveling the wings. After leveling off, the pilot started back to his airstrip. On short final, he noticed that he did not have enough time and distance to achieve a steady descent with only trim tabs to control the pitch. After a "go-around", the pilot attempted to set up for a shallow descent approach. At about 75 to 100 feet above the ground on final, the pilot felt "turbulence" and the airplane began descending quickly. The airplane then impacted the ground "pretty hard" breaking the left main landing gear, skidding about 40 feet, and coming to rest in an upright position. The fuselage sustained structural damage during the impact. Family members of the pilot and an FAA inspector examined the airplane after the accident. The elevator control cable was found liberated from its "Nicopress" fitting. The elevator cable had been replaced with a new cable by the pilot, under the supervision of a A&P mechanic on February 8, 2001. According to the pilot, the new elevator cable was fabricated for him by an aircraft maintenance facility. The airplane was given an annual inspection on March 6, 2001, by the same A&P mechanic who assisted with the elevator cable installation. The last time the airplane flew prior to the accident was on March 8, 2001, when the pilot flew the airplane for about 35 minutes with no anomalies. He stated that the airplane "performed great." ## Aircraft - Registration: [N9017L](https://openairdocs.org/deregistered/N9017L-2018-02-23), registration cancelled 2018-02-23, S/N 246-70, built 1970 (OpenAirDocs) - Reported make and model: Champion 7KCAB - Registry model: [Champion 7KCAB](https://openairdocs.org/model/champion-7kcab) (registry code 21101P3) (OpenAirDocs) - Registry engine: [Lycoming IO-320 series](https://openairdocs.org/engine/lycoming-io-320-series) (registry code 41509, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 246-70 - Airframe hours: 2983 - Engines: Lycoming IO-320-E2A 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, March 1, 2001, 1 hours before - Departed: 7LA3, Ragley, LA - Destination: 7LA3 ## Flight crew As NTSB recorded them.
