  > The pilot's failure to maintain control during a vertical, out of ground effect takeoff which resulted in a hard emergency landing. Factors were; the exceeded hover performance of the helicopter, the high density altitude, and the lack of suitable terrain for…
- [NTSB NYC98LA025](https://openairdocs.org/ntsb/NYC98LA025.md): Hughes 269B · Cleveland, OH · Accident · No injuries · Limited investigation · Final report · Oct 31, 1997 · N2273W · Substantial damage
  > the pilot's failure to recover from settling-with-power. Factors relating to the accident were: the pilot's downwind approach and low airspeed.
- [NTSB ATL95LA175](https://openairdocs.org/ntsb/ATL95LA175.md): Schweizer 269C · Hoover, AL · Accident · Serious injuries · Limited investigation · Final report · Sep 27, 1995 · N267RW · Substantial damage
  > The pilot's failure to maintain directional control when he positioned the helicopter in a hover so as to induce a loss of tail rotor effectiveness.
- [NTSB SEA93IA073](https://openairdocs.org/ntsb/SEA93IA073.md): Hughes 269B · Mcminnville, OR · Incident · No injuries · Incident investigation · Final report · Mar 5, 1993 · N9474F · Minor damage
  > An inflight loss of control, and inadequate remedial action. Factors include a tailwind, and gusts.
- [NTSB LAX93LA063](https://openairdocs.org/ntsb/LAX93LA063.md): Hughes 269B · Kahului, HI · Accident · No injuries · Limited investigation · Final report · Dec 7, 1992 · N9566F · Destroyed
  > Failure of the pilot to maintain adequate rotor RPM during downwind flight and adequate altitude to recover the loss of main rotor RPM before settling into the water. Contributing to the accident was the pilot's lack of rotorcraft flight experience.
- [NTSB CHI88FA190](https://openairdocs.org/ntsb/CHI88FA190.md): Mcdonnell Douglas 269B · Braceville, IL · Accident · 2 fatal · Field investigation · Final report · Aug 2, 1988 · N9522F · Destroyed
  > Conducting maneuvering flight the PIC failed to monitor the helicopter systems and allowed the main rotor RPM to decay to the point where it would not produce enough lift to sustain flight.
- [NTSB LAX87LA190](https://openairdocs.org/ntsb/LAX87LA190.md): Hughes 269B · Rubidoux, CA · Accident · Minor injuries · Limited investigation · Final report · Apr 26, 1987 · N101DN · Destroyed
  > A Hughes 269B went out of control and collided with the ground during a t/o to a hover. The pilot had purchased the aircraft recently and was learning to fly it. He was scheduled for his first flight lesson on the day of the accident. The CFI reported that he…
