  > The flight crew’s failure to maintain the proper airspeed on final approach, which resulted in an inadvertent aerodynamic stall and impact with trees, and terrain. Contributing to the accident was the flight crew’s fatigue due to the overnight flight schedule.
- [NTSB DCA17IA148](https://openairdocs.org/ntsb/DCA17IA148.md): Airbus A320-211 · San Francisco, CA · Incident · No injuries · Class 1 · Incident · Final report · Jul 8, 2017 · C-FKCK · No damage
  > The flight crew's misidentification of taxiway C as the intended landing runway, which resulted from the crewmembers' lack of awareness of the parallel runway closure due to their ineffective review of notice to airmen (NOTAM) information before the flight…
- [NTSB CEN15FA190](https://openairdocs.org/ntsb/CEN15FA190.md): Cessna 414A · Bloomington, IL · Accident · 7 fatal · Field investigation · Final report · Apr 7, 2015 · N789UP · Substantial damage
  > The pilot's failure to maintain control of the airplane during the instrument approach in night instrument meteorological conditions, which resulted in the airplane exceeding its critical angle of attack and an aerodynamic stall/spin. Contributing to the…
- [NTSB DCA13MA120](https://openairdocs.org/ntsb/DCA13MA120.md): Boeing 777-200ER · San Francisco, CA · Accident · 3 fatal · Class 1 · Major · Final report · Jul 6, 2013 · HL7742 · Destroyed
  > The flight crew's mismanagement of the airplane's descent during the visual approach, the pilot flying's unintended deactivation of automatic airspeed control, the flight crew's inadequate monitoring of airspeed, and the flight crew's delayed execution of a…
- [NTSB ERA12FA572](https://openairdocs.org/ntsb/ERA12FA572.md): Cessna 172S · Land O'Lakes, FL · Accident · 1 fatal · Field investigation · Final report · Sep 22, 2012 · N21750 · Substantial damage
