# NTSB CHI00LA119: Brice Rotorway Exec 162F, N627RM, Kimberling, MO, April 22, 2000 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: April 22, 2000, 12:14 local (17:14 UTC) - Place: Kimberling, MO - Coordinates: 36.640571, -93.419471 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=36.6406&lon=-93.4195&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report July 2, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 49043 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI00LA119 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/49043/pdf - Page: https://openairdocs.org/ntsb/CHI00LA119 ## Probable cause aircraft control not being maintained by the pilot. Factors to the accident were the encountered dynamic rollover and the uneven terrain. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, hover - terrain condition - rough/uneven (contributing factor) - aircraft control - not maintained, pilot in command (cause) - dynamic rollover - encountered, pilot in command (contributing factor) - Roll over, standing ## Analysis The pilot reported, 'After normal preflight, I lifted off into a hover an air taxied approx 120' towards runway. I sat the helicopter down to turn on my avionics switch. I must not have lowered collective fully, as when I removed my hand from the cyclic, & the wind shifted (which is common at this airport) slightly to right front quarter, it displaced the rotor blades causing a dynamic rollover to the left.' The pilot stated, 'I was concentrating on my slope landing and thinking of my subsequent slope departure so thoroughly I that I did not positively notice rotor rpm dropping as I should have before taking my hand off the cyclic.' The pilot reported that the accident could have been prevented by, 'Lowering collective fully before removing hand from cyclic'. ## Factual narrative On April 22, 2000, at 1214 central daylight time, a Brice Rotorway Exec 162F, N627RM, owned/built/piloted by a airline transport pilot, sustained substantial damage when the helicopter rolled-over following a loss of control at the Kimberling Airways Airport, Kimberling City, Missouri. Visual meteorological conditions prevailed at the time of the accident. The personal flight was operating under the provisions of 14 CFR Part 91 and was not on a flight plan. The pilot, the sole occupant, reported no injuries. The local flight was originating at the time of the accident. According to the pilot's written statement, "After normal preflight, I lifted off into a hover an air taxied approx 120' towards runway. I sat the helicopter down to turn on my avionics switch. I must not have lowered collective fully, as when I removed my hand from the cyclic, & the wind shifted (which is common at this airport) slightly to right front quarter, it displaced the rotor blades causing a dynamic rollover to the left." The pilot stated, "I was concentrating on my slope landing and thinking of my subsequent slope departure so thoroughly I that I did not positively notice rotor rpm dropping as I should have before taking my hand off the cyclic." The pilot reported that the accident could have been prevented by, "Lowering collective fully before removing hand from cyclic". ## Aircraft - Registration: [N627RM](https://openairdocs.org/deregistered/N627RM-2006-05-18), registration cancelled 2006-05-18, S/N 6203, built 1999 (OpenAirDocs) - Reported make and model: Brice ROTORWAY EXEC 162F (ROTORWAY E) - Registry model: [Brice Ronald R EXEC 162F](https://openairdocs.org/model/brice-ronald-r-exec-162f) (registry code 05606UF) (OpenAirDocs) - Registry engine: [Amateur-built UNKNOWN ENG](https://openairdocs.org/engine/amateur-built-unknown-eng) (registry code 99999) (OpenAirDocs) - Category: Helicopter, amateur-built - Serial number: 6203 - Airframe hours: 61 - Engines: Rotorway 162F 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Roanald Ray Brice - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Annual, December 7, 1999, 11 hours before - Departed: MO64 - Airport: M064, Kimberling Airways ## 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.
