The NTSB has released the final report for the Nov. 18, 2022, in-flight breakup of a Cessna 208B Grand Caravan EX single-engine turboprop during flight testing for a new supplemental type certificate program near Snohomish, Washington. All four occupants of the Caravan were killed.

This flight test was part of a series to test a Raisbeck Engineering drag-reduction system (DRS) on the Caravan EX, to expand the applicability of the DRS to another modification on the airplane, the AeroAcoustics Aircraft Systems Aircraft Payload Extender (APE III), although the DRS was not installed on the accident aircraft.
