The Unseen: Dark of Night Is No Time to Improvise

NTSB investigation reveals spatial disorientation, but the full story offers deeper insights into a tragic accident.

Key Takeaways:

  • A fatal night takeoff crash of a Cherokee 140 at Canyonlands Regional Airport was attributed to the pilot's spatial disorientation and loss of visual reference in the dark.
  • Contributing factors included the pilot's decision not to use pilot-controlled runway lights and initiating an immediate, excessively steep turn after takeoff without sufficient altitude.
  • Operating at a high density altitude and near gross weight, the aircraft lost critical altitude during the steep turn, leading to an impact with rising terrain.

Moab, utah lies nestled in a bend in the Colorado River, a green dot in a Martian landscape of ochre plains and low rocky outcrops that resemble the protruding vertebrae of buried monsters.

Sixteen miles northwest of Moab is Canyonlands Regional Airport (KCYN). Its runway, 100 feet wide and 7,360 feet long, is oriented 03/21. All of the airport’s buildings are at its north end, alongside the highway that leads to Moab.
