## Latest cases

- [NTSB DEN07FA003](https://openairdocs.org/ntsb/DEN07FA003.md): Extra Flugzeugbau EA 300/L · Tucumcari, NM · Accident · 1 fatal · Field investigation · Final report · Oct 4, 2006 · N300BB · Substantial damage
  > The pilot's failure to maintain aircraft control during aerobatic flight, resulting in an inadvertent accelerated stall. Contributing factors include the low altitude for recovery from the loop and the high density altitude.
- [NTSB LAX06LA262](https://openairdocs.org/ntsb/LAX06LA262.md): Extra Flugzeugbau EA-300 · Mojave, CA · Accident · Serious injuries · Limited investigation · Final report · Aug 16, 2006 · N12DW · Substantial damage
  > the pilot's failure to maintain an adequate airspeed while performing low-level aerobatics that resulted in an inadvertent accelerated stall and in-flight collision with terrain.
- [NTSB ANC06LA026](https://openairdocs.org/ntsb/ANC06LA026.md): Extra Flugzeugbau 300S · Greenfield, CA · Accident · 1 fatal · Limited investigation · Final report · Mar 21, 2006 · N124X · Substantial damage
  > The pilot's failure to maintain adequate airspeed during the base leg to final approach phase of a VFR landing pattern, which resulted in an inadvertent stall and an uncontrolled descent. A factor contributing to the accident was the inadvertent stall/mush.
- [NTSB NYC04LA006](https://openairdocs.org/ntsb/NYC04LA006.md): Extra Flugzeugbau EA-300L · Queen Anne, MD · Accident · 1 fatal · Limited investigation · Final report · Oct 12, 2003 · N18NL · Destroyed
  > The pilot's performance of aerobatic maneuvers with positive and negative Gs, which resulted in a G induced loss of control, and uncontrolled impact with the ground.
- [NTSB NYC04LA004](https://openairdocs.org/ntsb/NYC04LA004.md): Pfeifler Edge-540 · Warrenton, VA · Accident · 1 fatal · Limited investigation · Final report · Oct 7, 2003 · N540SH · Destroyed
  > The pilot's failure to maintain aircraft control while performing aerobatic maneuvers.
- [NTSB NYC03FA088](https://openairdocs.org/ntsb/NYC03FA088.md): Aviat Pitts S-2B · Newport, PA · Accident · 2 fatal · Field investigation · Final report · Apr 24, 2003 · N6085U · Substantial damage
  > The pilot's improper decision to perform aerobatics at a low altitude, which inhibited his ability to recover from an encountered flat spin. A factor related to the accident was the aft center of gravity, which was beyond the operational limit for the…
- [NTSB LAX03LA081](https://openairdocs.org/ntsb/LAX03LA081.md): Pitts S-2B · Long Beach, CA · Accident · Serious injuries · Limited investigation · Final report · Feb 1, 2003 · N300PS · Substantial damage
  > The pilot's excessive pull up, which resulted in a failure to obtain/maintain flying speed and a subsequent stall/mush.
- [NTSB NYC01FA212](https://openairdocs.org/ntsb/NYC01FA212.md): Pitts S-2B · Shirley, NY · Accident · 1 fatal · Field investigation · Final report · Aug 21, 2001 · N225SD · Substantial damage
  > The pilot under instruction's failure to maintain adequate airspeed, and the flight instructor's inadequate remedial action during a simulated engine-out approach, which resulted in an inadvertent stall, and subsequent ground impact.
- [NTSB MIA01FA041](https://openairdocs.org/ntsb/MIA01FA041.md): Christen Industries Pitts S-2B · Weston, FL · Accident · 2 fatal · Field investigation · Final report · Dec 14, 2000 · N260DB · Substantial damage
  > An inflight loss of control by both pilots while maneuvering, which resulted in an inverted flat spin, an uncontrolled descent, and an impact with terrain/water. A factor contributing to the accident was the failure of both pilots to ensure that the…
- [NTSB ATL96LA025](https://openairdocs.org/ntsb/ATL96LA025.md): Moravan Zlin Z50 LA · Springfield, TN · Accident · 1 fatal · Limited investigation · Final report · Dec 20, 1995 · N6660B · Destroyed
  > the pilot's failure to maintain control of the aircraft.
- [NTSB FTW95LA384](https://openairdocs.org/ntsb/FTW95LA384.md): Johnson Rebel 300 · Keenesburg, CO · Accident · 1 fatal · Limited investigation · Final report · Sep 9, 1995 · N36DJ · Destroyed
  > Inadvertent stall during approach. A factor was the pilot's lack of total experience in make and model.
- [NTSB BFO93LA045](https://openairdocs.org/ntsb/BFO93LA045.md): Pitts S-2B · Hillsboro, MD · Accident · Serious injuries · Limited investigation · Final report · Mar 7, 1993 · N12QW · Destroyed
  > Failure of the pilot to maintain airspeed, while performing aerobatic maneuvers, which resulted in an inadvertent flat spin and an uncontrolled descent into terrain.
