  > The pilot's failure to maintain directional control during the landing roll in gusting wind conditions.
- [NTSB ANC17FA012](https://openairdocs.org/ntsb/ANC17FA012.md): Piper PA 11 · Aniak, AK · Accident · 2 fatal · Field investigation · Final report · Dec 16, 2016 · N5028H · Substantial damage
  > The pilot's intentional flight of the airplane into terrain in an act of suicide.
- [NTSB GAA16CA495](https://openairdocs.org/ntsb/GAA16CA495.md): Piper PA 11 · Grand Isle, VT · Accident · No injuries · Data collection · Final report · Sep 19, 2016 · N4681M · Substantial damage
  > The pilot's failure to maintain adequate airspeed and his exceedance of the airplane’s critical angle-of-attack during a simulated engine failure and forced landing with a tailwind, which resulted in an aerodynamic stall.
- [NTSB CEN16FA370](https://openairdocs.org/ntsb/CEN16FA370.md): Piper PA 11 · Arcanum, OH · Accident · 2 fatal · Field investigation · Final report · Sep 14, 2016 · N4910M · Substantial damage
  > The student pilot's reckless flying attitude and use of multiple psychoactive drugs, which likely impaired his ability to maintain clearance from terrain while maneuvering at low altitude.
- [NTSB CEN16LA310](https://openairdocs.org/ntsb/CEN16LA310.md): Piper PA-11 · Indianola, IA · Accident · 2 fatal · Limited investigation · Final report · Aug 5, 2016 · N4707M · Destroyed
  > The pilot's inadequate preflight planning, which resulted in the airplane being operated above its maximum gross weight, degraded its climb performance, and led to an aerodynamic stall during the initial climb.
- [NTSB ERA14LA261](https://openairdocs.org/ntsb/ERA14LA261.md): Piper PA-11 · Cooperstown, NY · Accident · No injuries · Limited investigation · Final report · May 26, 2014 · N4550M · Substantial damage
  > The pilot’s delayed use of carburetor heat during the approach to landing, which resulted in the formation of carburetor ice, a partial loss of engine power, and the airplane’s subsequent inability to sustain flight.
- [NTSB ANC11CA078](https://openairdocs.org/ntsb/ANC11CA078.md): Piper PA-11 · Chenga Bay, AK · Accident · No injuries · Data collection · Final report · Aug 11, 2011 · N78635 · Substantial damage
  > The pilot's improper decision to land on an unsuitable landing surface which resulted in a nose over.
- [NTSB ANC10FA076](https://openairdocs.org/ntsb/ANC10FA076.md): Piper PA-11 · Willow, AK · Accident · 2 fatal · Field investigation · Final report · Aug 25, 2010 · N78831 · Substantial damage
  > The pilot’s failure to maintain adequate airspeed, which resulted in an aerodynamic stall/spin and impact with the ground.
- [NTSB ERA09LA503](https://openairdocs.org/ntsb/ERA09LA503.md): Piper PA-11 · Quincy, FL · Accident · 1 fatal · Limited investigation · Final report · Sep 7, 2009 · N4778M · Substantial damage
  > The pilot’s improper use of flight controls following a partial loss of engine power for undetermined reasons. Contributing to the accident was the pilot’s impairment from the use of an over-the-counter sedating antihistamine.
- [NTSB LAX08CA275](https://openairdocs.org/ntsb/LAX08CA275.md): Piper PA-11 · Sheridan, WY · Accident · No injuries · Data collection · Final report · Aug 21, 2008 · N1106T · Substantial damage
  > The pilot's inadequate compensation for the existing gusty wind conditions and likely windshear encounter and his failure to maintain an adequate airspeed that resulted in a stall/mush.
