[11] In May 2018, ground tests continued, and all major components were being fabricated, including the nose, fuselage, wings and the tail cone.

[15] By October 2019, the first flight was pushed back by GE Catalyst testing delays, with Textron expecting its first turboprop in 2020.

[16] By July 2021, the turboprop engine was to have its maiden flight in a King Air 350 testbed aircraft in the coming months.

[17] A Catalyst engine was installed on a Denali airframe to make its first flight before year-end and to achieve aircraft certification in 2023.

[22] As of May 6, 2024, the Beechcraft Denali has reached key milestones, with Textron confirming the start of its flight test phase following FAA Type Inspection Authorization.

[15] To lower the number of holes and fasteners needed, large parts like the wing spar and main doors are monolithically machined from a single aluminum billet, or chemically milled like the titanium firewall.
