The Transportation Safety Board (TSB) suggests the failure of a primary flight instrument could be a key factor into a plane crash that killed two Air Tindi pilots outside of Whati on Jan. 30. The King Air 200 aircraft is equipped with two attitude indicators — flight instruments that provide pitch and roll information. According to Jeremy Warkentin, technical investigator for the TSB, one attitude indicator wasn't functioning when the flight took off, but the crew flew anyway. He said the pilots, Will Hayworth and ZachMcKillop, had started their descent when the second attitude indicator suddenly failed. For that type of plane, Warkentin said the normal rate of descent is 1,000 to 2,000 feet a minute.
