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 CEN14FA035](https://openairdocs.org/ntsb/CEN14FA035.md): Beech C90 · Springdale, AR · Accident · 2 fatal · Field investigation · Final report · Nov 1, 2013 · N269JG · Destroyed
  > A total loss of power to both engines due to fuel exhaustion. Also causal were the pilot’s reliance on the fuel totalizer rather than the fuel quantity gauges to determine the fuel on board and his improper fuel planning.
- [NTSB WPR14CA013](https://openairdocs.org/ntsb/WPR14CA013.md): Piper PA 28-180 · Cody, WY · Accident · Serious injuries · Data collection · Final report · Oct 11, 2013 · N31BA · Substantial damage
  > A loss of engine power during climb to cruise for reasons that could not be determined due to no postaccident examination.
- [NTSB ERA13LA429](https://openairdocs.org/ntsb/ERA13LA429.md): De Havilland DH 82A · Rhinebeck, NY · Accident · No injuries · Limited investigation · Final report · Sep 22, 2013 · N9410 · Substantial damage

- [NTSB ERA13FA256](https://openairdocs.org/ntsb/ERA13FA256.md): Piper PA-32R-300 · Macon, GA · Accident · 2 fatal · Field investigation · Final report · May 27, 2013 · N4489F · Destroyed
  > A total loss of engine power due to oil starvation for reasons that could not be determined due to extensive postcrash fire and heat damage to the engine components.
- [NTSB ERA13LA254](https://openairdocs.org/ntsb/ERA13LA254.md): Fleming Eldridge E Sonex · Naples, FL · Accident · Serious injuries · Limited investigation · Final report · May 26, 2013 · N634SX · Substantial damage

- [NTSB CEN13LA164](https://openairdocs.org/ntsb/CEN13LA164.md): Bellanca 17-30A · Morris, IL · Accident · No injuries · Limited investigation · Final report · Feb 16, 2013 · N93747 · Substantial damage
  > The pilot's improper fuel management, which resulted in a loss of engine power due to fuel exhaustion.
- [NTSB WPR13CA107](https://openairdocs.org/ntsb/WPR13CA107.md): Robinson R22 · Kona, HI · Accident · No injuries · Data collection · Final report · Jan 30, 2013 · N333PJ · Substantial damage
  > The pilot’s failure to maintain adequate main rotor rpm during a practice autorotation and the flight instructor's delayed action, which resulted in a hard landing.
- [NTSB WPR13LA099](https://openairdocs.org/ntsb/WPR13LA099.md): Goetz Helicycle · Mesa, AZ · Accident · No injuries · Limited investigation · Final report · Jan 22, 2013 · N143PG · Substantial damage
  > The pilot's failure to properly install and secure the wire connecting the electronic speed controller unit to the fuel controller actuator motor, which resulted in the wire’s disconnection in flight and the resultant partial loss of engine power.
- [NTSB ERA13LA116](https://openairdocs.org/ntsb/ERA13LA116.md): Robinson Helicopter R22 Beta · Ellington, CT · Accident · Minor injuries · Limited investigation · Final report · Jan 17, 2013 · N26NE · Substantial damage
