NTSB releases report on Chamberlain, South Dakota plane crash | #itsecurity | #infosec | #education | #technology | #infosec

The National Transportation Safety Board released the official docket of information relating to the November 2019 Chamberlain plane crash that killed nine people and seriously injured three people who were flying to Idaho.

Members of a prominent eastern Idaho family were returning home from an annual South Dakota hunting trip when their Pilatus PC-12 crashed minutes after takeoff from the Chamberlain airport on Nov. 30. Passengers’ ages ranged from 7 to 81, and the three survivors were transported to South Dakota hospitals.

In the aircraft performance and simulation study, conducted on Sept. 17, 2021, the team found that the pilot of the Pilatus PC-12 made several operational errors from his attempts to remove snow and ice from the aircraft, an overweighed aircraft to the conditions during takeoff that led to the crash — the deadliest in South Dakota since 1968.

Previous reporting by the Argus found that evidence from the preliminary NTSB report “indicates the airplane was out of control the moment it took off.”

Among the victims were Jim Hansen Sr. and his sons, Kirk and Jim Hansen Jr., and six other family members. 

The crash also killed Kirk Hansen’s children, Stockton and Logan; his sons-in-law, Kyle Taylor and Tyson Dennert; and Jim Hansen’s son, Jake, and grandson, Houston.

Here’s what we learned from the multiple-page report:

Ice and weather conditions were a major factor

Ice on the wings and other parts of the plane were a major factor in the crash, according to the report.

In a photo of the plane before the crash, someone can be seen clearing snow and ice from the left wing.

But the pilot was deicing the plane while snow was falling and “he did not completely remove snow and ice accumulations from the vertical and horizontal stabilizers.”

Ten minutes before takeoff, there were visible icicles on the horizontal stab bullet fairing, according to the report. There was also more snow falling than there had been an hour before. 

Video from the crash also shows a snowed-over runway. 

A transcript from the in-aircraft communication catches someone asking if the runway was in good condition and someone responding that the runway was not entirely clear.
