## Latest cases

- [NTSB CEN25LA067](https://openairdocs.org/ntsb/CEN25LA067.md): Robinson Helicopter R44 · Galveston, TX · Accident · No injuries · Class 4 · Limited · Final report · Dec 31, 2024 · N441HQ · Substantial damage
  > The pilot’s failure to maintain terrain clearance during the takeoff from the helipad in high and gusting wind conditions, that resulted in the right skid extension embedding in the artificial turf, and a subsequent dynamic rollover sequence.
- [NTSB ERA16LA301](https://openairdocs.org/ntsb/ERA16LA301.md): Means Rober C Rotorway Exec · Iron Station, NC · Accident · Minor injuries · Limited investigation · Final report · Aug 26, 2016 · N48KM · Substantial damage
  > The pilot’s failure to maintain adequate clearance from the ground while hovering, which resulted in separation of the forward section of the right skid tube with counterweight attached, a sudden center of gravity (CG) shift outside the normal operating…
- [NTSB CEN14LA269](https://openairdocs.org/ntsb/CEN14LA269.md): Schweizer 269C · Temple, TX · Accident · No injuries · Limited investigation · Final report · May 31, 2014 · N902CP · Substantial damage
