# NTSB ATL01LA100: Rockwell S2R, N8438V, Bentonia, MS, August 29, 2001 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: August 29, 2001, 15:00 local (20:00 UTC) - Place: Bentonia, MS - Coordinates: 32.639198, -90.36959 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=32.6392&lon=-90.3696&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report June 3, 2002 - Report: Approved by Office Director - Parties: Jackson FSDO - NTSB case key (mKey): 53241 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ATL01LA100 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/53241/pdf - Page: https://openairdocs.org/ntsb/ATL01LA100 ## Probable cause The loss of engine power due to the loss of throttle cable continunity. The throttle cable linkage was worn beyond servicable limits. A factor was uneven terrain at the emergency landing site. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, maneuvering - aerial application - throttle/power lever,linkage - worn (cause) - Forced landing, descent - emergency - In flight collision with terrain/water, emergency landing - terrain condition - rough/uneven (contributing factor) ## Analysis The pilot had sprayed two fields and was enroute to a third field when the engine lost power. After efforts by the pilot to restore full power failed, the pilot selected a nearby field and executed an emergency descent for an emergency landing. During touchdown and landing roll, the airplane collided with an embankment. The examination of the airplane at the accident site, revealed that the throttle linkage to the carburetor was not connected. The examination disclosed that the cable assembly was worn beyond servicable limits. The maintenance history of the cable assembly was not determined. ## Factual narrative On August 29, 2001, at 1500 central daylight time, a Rockwell S2R, N8438V, collided with the ground during an attempted forced landing near Bentonia, Mississippi. The agricultural flight was operated by Nash Agricultural services under the provisions of 14 CFR Part 137 with no flight plan filed. Visual weather conditions prevailed at the time of the accident. The airplane sustained substantial damage, and the commercial pilot was not injured. The flight departed a private airstrip in Bentonia, Mississippi, at 1405. According to the operator, the pilot had sprayed two fields and was enroute to a third field when the engine lost power. After efforts by the pilot to restore full power failed, the pilot selected a nearby field and executed an emergency descent for an emergency landing. During touchdown and landing roll, the airplane collided with an embankment. The pilot reported that he noticed the uneven terrain on final approach to land in the field. The examination of the airplane at the accident site, revealed that the throttle linkage to the carburetor was not connected. The examination disclosed that the cable assembly was worn beyond servicable limits. The maintenance history of the cable assembly was not determined. ## Aircraft - Registration: [N8438V](https://openairdocs.org/deregistered/N8438V-2014-11-20), registration cancelled 2014-11-20, S/N 2198R, built 1976 (OpenAirDocs) - Reported make and model: Rockwell S2R - Registry model: [Rockwell International S-2R](https://openairdocs.org/model/rockwell-international-s-2r) (registry code 7630202) (OpenAirDocs) - Registry engine: [Pratt & Whitney R1340 series](https://openairdocs.org/engine/pratt-whitney-r1340-series) (registry code 52016, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 2198R - Airframe hours: 9426 - Engines: P&W R-1340 600 horsepower reciprocating - Damage: Substantial damage - Flight: Aerial application, Part 137 - Registered owner: Nash Ag Service Inc., - Airworthiness certificate: Special, Restricted (Special) - Departed: PVT, Bentonia, MS ## 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.
