# NTSB CHI99LA021: Jordan Acey Deucy P70, N597HJ, Ava, MO, October 30, 1998 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: October 30, 1998, 11:30 local (17:30 UTC) - Place: Ava, MO - Coordinates: 36.950378, -92.660591 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=36.9504&lon=-92.6606&mi=10 - Phase of flight: [Initial climb](https://openairdocs.org/ntsb-phases/350) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report February 16, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 45185 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI99LA021 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/45185/pdf - Page: https://openairdocs.org/ntsb/CHI99LA021 ## Probable cause the pilot's attempted operation of the airplane with known deficiencies, and his not obtaining control of the airplane in flight. A factor was asymmetrical ailerons. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, takeoff - initial climb - flt control syst,aileron control - asymmetrical (contributing factor) - operation with known deficiencies in equipment - attempted, pilot in command (cause) - aircraft control - not obtained, pilot in command (cause) - In flight collision with terrain/water, descent - uncontrolled ## Analysis The pilot purchased the amateur built airplane already constructed. On his first flight he reported a lack of aileron control at slow speed. He attempted to obtain the services of another pilot to fly the airplane and evaluate it. The other pilot made a high speed taxi test and then refused to fly the airplane. The owner/pilot then attempted a flight, lost control on liftoff and impacted the terrain. An inspection of the airplane after the accident revealed asymmetric deflection of the ailerons. The right aileron deflected 6' in either direction, while the left aileron deflected 3' in each direction. ## Factual narrative On October 30, 1998, at 1130 central standard time, an amateur built Acey Deucy P70, N597HJ, sustained substantial damage following loss of control during initial climb on takeoff from runway 31 (3,634' X 50' dry/asphalt) near Ava, Missouri. The pilot reported minor injuries. He said that this was his second flight in the airplane and that on liftoff he experienced a loss of roll authority. The personal 14 CFR art 91 flight was operating in visual meteorological conditions. No flight plan was on file. The flight was originating at the time of the accident with the intended destination of a private strip near Gainesville, Missouri. The pilot indicated that he purchased the amateur built airplane already constructed and with about 200 hours time in service. He indicated that he had conducted one previous flight in the airplane. He reported during that flight roll authority was poor at low speed; however, improved as the airspeed built up. He said he had asked another pilot to fly the airplane and check it out for him. He said that the other pilot tried the airplane in a high speed taxi test and refused to fly it. He then attempted to fly the airplane himself. On takeoff he lost control at initial liftoff. The airplane turned right and impacted the terrain. An inspection of the airplane subsequent to the accident revealed that the right aileron deflected 6" in each direction and the left aileron deflected 3" in each direction. ## Aircraft - Registration: [N597HJ](https://openairdocs.org/deregistered/N597HJ-2001-04-09), registration cancelled 2001-04-09, S/N AD-215 (OpenAirDocs) - Reported make and model: Jordan ACEY DEUCY P70 (ACEY DEUCY) - Registry model: [Jordan Henry J ACEY DEUCY P70](https://openairdocs.org/model/jordan-henry-j-acey-deucy-p70) (registry code 05650G9) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: AD-215 - Airframe hours: 205 - Engines: Lycoming O-290-G 130 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: William R.
