## Latest cases

- [NTSB LAX96FA049](https://openairdocs.org/ntsb/LAX96FA049.md): Beech S35 · Oxnard, CA · Accident · 1 fatal · Field investigation · Final report · Nov 19, 1995 · N5795K · Destroyed
  > failure of the pilot to maintain adequate airspeed during a missed approach, after encountering an undetermined propeller malfunction, which resulted in a stall and collision with the terrain. Factors relating to the accident were: darkness, fog, and the…
- [NTSB BFO96LA015](https://openairdocs.org/ntsb/BFO96LA015.md): Piper PA-28-180 · Lebanon, VA · Accident · No injuries · Limited investigation · Final report · Oct 30, 1995 · N477SP · Destroyed
  > failure of the propeller blade due to fatigue cracking originating from corrosion damage. A related factor was the soft terrain encountered during the forced landing.
- [NTSB SEA96LA008](https://openairdocs.org/ntsb/SEA96LA008.md): Nord Stampe SV4C · Cottage Grove, OR · Accident · No injuries · Limited investigation · Final report · Oct 15, 1995 · N51SV · Substantial damage
  > A propeller blade separation due to inadequate material. The lack of a suitable area for the forced landing was a factor.
- [NTSB FTW96FA009](https://openairdocs.org/ntsb/FTW96FA009.md): Rupe RV-4 · Longmont, CO · Accident · 1 fatal · Field investigation · Final report · Oct 7, 1995 · N61TR · Destroyed
  > the installation of an unapproved metal propeller which led to a fatigue failure of a blade and loss of aircraft control.
- [NTSB ANC95IA173](https://openairdocs.org/ntsb/ANC95IA173.md): Piper PA-28-181 · Gustavus, AK · Incident · No injuries · Incident investigation · Final report · Sep 22, 1995 · N38293 · No damage
  > fatigue failure of the propeller blade due to previous foreign object damage.
- [NTSB LAX95LA314](https://openairdocs.org/ntsb/LAX95LA314.md): Piper PA-23-250 · Marana, AZ · Accident · 1 fatal · Limited investigation · Final report · Aug 30, 1995 · N7156T · Destroyed
  > the pilot's poor installation of the propeller which allowed the propeller to become loose, and the pilot's improper emergency procedure by feathering the wrong propeller.
- [NTSB ANC95IA151](https://openairdocs.org/ntsb/ANC95IA151.md): Piper PA-28-181 · Juneau, AK · Incident · No injuries · Incident investigation · Final report · Aug 26, 1995 · N2937X · Minor damage
  > failure and separation of the propeller blade due to foreign object damage and fatigue.
- [NTSB DCA95MA054](https://openairdocs.org/ntsb/DCA95MA054.md): Embraer EMB-120RT · Carrollton, GA · Accident · 8 fatal · Class 1 · Major · Final report · Aug 21, 1995 · N256AS · Destroyed
  > the in-flight fatigue fracture and separation of a propeller blade resulting in distortion of the left engine nacelle, causing excessive drag, loss of wing lift, and reduced directional control of the airplane. The fracture was caused by a fatigue crack from…
- [NTSB ANC95LA131](https://openairdocs.org/ntsb/ANC95LA131.md): Piper PA-18-160 · Port Alsworth, AK · Accident · No injuries · Limited investigation · Final report · Aug 6, 1995 · N814JM · Substantial damage
  > An in-flight separation of a propeller blade, which resulted in a severe vibration, shutdown of the engine, and a forced landing in alder bushes.
- [NTSB NYC95LA137](https://openairdocs.org/ntsb/NYC95LA137.md): Field VARI-EZE · Malone, NY · Accident · No injuries · Limited investigation · Final report · Jul 1, 1995 · CGMEZ · Substantial damage
  > failure of the propeller speed reduction unit due to an inadequate design change by the manufacturer, which resulted in a complete loss of thrust. A factor was the rough terrain.
