## Latest cases

- [NTSB DFW05CA189](https://openairdocs.org/ntsb/DFW05CA189.md): Rockwell International S-2R · Hamlin, TX · Accident · No injuries · Data collection · Final report · Jul 23, 2005 · N4946X · Substantial damage
  > The failure of the propeller blade seal resulting in an oil leak. Contributing factors were the limited forward visibility and lack of suitable terrain for the precautionary landing.
- [NTSB DFW05CA158](https://openairdocs.org/ntsb/DFW05CA158.md): Rose Parakeet A-1 · Boyd, TX · Accident · Minor injuries · Data collection · Final report · Jun 10, 2005 · NC18252 · Substantial damage
  > The in-flight separation of the outboard section of the propeller for unknown reasons. A contributing factor was the lack of suitable terrain for the forced landing.
- [NTSB FTW04LA013](https://openairdocs.org/ntsb/FTW04LA013.md): Prill RV-6 · Snyder, TX · Accident · Minor injuries · Limited investigation · Final report · Oct 17, 2003 · N3XS · Substantial damage
  > The failure of the propeller blade for undetermined reason. A contributing factor was the lack of suitable terrain.
- [NTSB FTW03LA171](https://openairdocs.org/ntsb/FTW03LA171.md): Boyle Black Eagle BE360 · Celina, TX · Accident · Minor injuries · Limited investigation · Final report · May 23, 2003 · N72BJ · Substantial damage
  > The loss of propeller pitch effectiveness for undetermined reasons. A contributing factor was the lack of suitable terrain for the forced landing.
- [NTSB FTW01LA005](https://openairdocs.org/ntsb/FTW01LA005.md): Holt Thorpe T-18C · Imperial, TX · Accident · 2 fatal · Limited investigation · Final report · Oct 4, 2000 · N85LH · Destroyed
