Aftermath: First There Is a Mountain

Gemini Sparkle

Key Takeaways:

  • An experienced pilot crashed his Cessna 182 into mountainous terrain after mistakenly programming his GPS for a seaplane base instead of the intended airport.
  • This small navigational error directed the aircraft onto a path intersecting high terrain, which the pilot attempted to avoid by climbing sharply, but ultimately led to the crash.
  • The accident highlights the critical danger of "clerical errors" in digital navigation, as two GPS units provided no redundancy when both reflected the same incorrect destination.
  • The article emphasizes the importance of independent situational awareness, advocating for visual navigation and cross-referencing ("pilotage") to verify digital information and prevent such fatal mistakes.

The 77-year-old, 8,000 hour pilot-owner of a Cessna 182, accompanied by his wife, flew from Anchorage to Juneau, Alaska, on a July afternoon. The couple was in the process of moving to Hoonah, about 31 nm west-southwest of Juneau; the ostensible purpose of this trip was to position the 182 there before the start of winter. The pilot’s wife intended to return to Anchorage, but the 505 nm IFR trip took longer than expected, and her Alaska Airlines flight was taxiing out when they arrived. She rebooked for the following morning, and the couple then flew over to Hoonah for the night.

Her flight back to Anchorage was to depart at 7:28 a.m. At 6:43 a.m., the local controller at Juneau received a call from the pilot, reporting 10 miles southwest for landing. The controller told him to report four miles out. A moment later, a faint ELT signal was picked up in the tower and also at the Juneau Flight Service Station.
