  - wrong runway - selected, pilot in command (contributing factor)
  - weather condition - high density altitude (contributing factor)
  - proper climb rate - not possible, pilot in command (cause)
  - terrain condition - rising (contributing factor)
  - stall/mush - inadvertent, pilot in command (cause)
