## Latest cases

- [NTSB WPR18LA145](https://openairdocs.org/ntsb/WPR18LA145.md): Sportavia Putzer RF5B Sperber · Lookout Pass, MT · Accident · Minor injuries · Limited investigation · Final report · May 22, 2018 · N66GL · Substantial damage
  > The pilot’s improper decision to continue flight toward rising terrain after the engine overheated, which necessitated a precautionary landing when the motorglider could not maintain altitude in downdrafts.
- [NTSB WPR17LA064](https://openairdocs.org/ntsb/WPR17LA064.md): Beech A36TC · Stevensville, MT · Accident · Minor injuries · Limited investigation · Final report · Feb 23, 2017 · N3803J · Substantial damage
  > The pilot's decision to conduct a takeoff with a tailwind on an upsloping runway in an overweight airplane, which resulted in the airplane having insufficient energy to climb out of ground effect.
- [NTSB WPR14LA220](https://openairdocs.org/ntsb/WPR14LA220.md): Aero Commander Callair A 9B · Gardiner, MT · Accident · Serious injuries · Limited investigation · Final report · Jun 2, 2014 · N7292V · Substantial damage
  > The pilot’s inadequate preflight planning and his subsequent takeoff with the airplane over its allowable gross weight in high density altitude conditions, which degraded the airplane’s climb performance and led to a subsequent forced landing.
- [NTSB WPR13CA325](https://openairdocs.org/ntsb/WPR13CA325.md): Boeing E75 · Bozeman, MT · Accident · No injuries · Data collection · Final report · Jul 14, 2013 · N5176N · Substantial damage
