# NTSB investigations: Rockwell International S-2R: Loss of engine power (total)

NTSB aviation accident and incident investigations since 1962: the probable cause, findings, aircraft, crew, weather and docket of each, linked to the FAA registry and the FAA’s own reports.

## Latest cases

- [NTSB CEN26LA221](https://openairdocs.org/ntsb/CEN26LA221.md): Rockwell International S-2R · Gause, TX · Accident · No injuries · Class 4 · Limited · Final report · May 20, 2026 · N4990X · Substantial damage

- [NTSB CEN19LA156](https://openairdocs.org/ntsb/CEN19LA156.md): Rockwell S 2R · Oakes, ND · Accident · No injuries · Class 3 · Limited · Final report · May 25, 2019 · N4907X · Substantial damage
  > The failure of the helical cam gear of the engine assembly due to fatigue cracks in the gear teeth, which resulted in a total loss of engine power.
- [NTSB CEN14CA442](https://openairdocs.org/ntsb/CEN14CA442.md): Rockwell International S 2R · Kerkhoven, MN · Accident · No injuries · Data collection · Final report · Aug 19, 2014 · N9646A · Substantial damage
  > The pilot failure to see and avoid the guide wire during the aerial application flight.
- [NTSB CEN13LA484](https://openairdocs.org/ntsb/CEN13LA484.md): Rockwell International S-2R · Larchwood, IA · Accident · No injuries · Limited investigation · Final report · Aug 12, 2013 · N5610X · Substantial damage
  > A complete loss of engine power during an agricultural application flight for reasons that could not be determined because postaccident examinations did not reveal any anomalies that would have precluded normal operation.
- [NTSB WPR12CA172](https://openairdocs.org/ntsb/WPR12CA172.md): Rockwell International S-2R · Palouse, WA · Accident · No injuries · Data collection · Final report · Apr 17, 2012 · N4971X · Substantial damage
  > The pilot’s inadequate fuel planning, which resulted in a total loss of engine power due to fuel exhaustion. Contributing to the accident was the pilot’s distraction and subsequent failure to have the airplane refueled.
- [NTSB WPR11LA279](https://openairdocs.org/ntsb/WPR11LA279.md): Rockwell International S-2R · Brawley, CA · Accident · Serious injuries · Limited investigation · Final report · Jun 23, 2011 · N8520V · Substantial damage
  > The partial loss of engine power shortly after takeoff, which likely resulted from the failure of the piston connecting rod in cylinder number 3 due to hydraulic lock in that cylinder.
