[2] Learjet 85 had a 9.75 m pressure fuselage shell, which was created in an out-of-autoclave process in Querétaro, Mexico. The wing, composed of a composite shell over steel frames, was made in Belfast. Final assembly was by Learjet in Wichita.
[3] In Jan 2008, Bombardier announced that German-Swiss Grob Aerospace AG would design and construct three Learjet 85 prototypes. By Aug 2008, Grob was insolvent. On 18 Sept 2008, Bombardier announced that it was dropping Grob as Learjet 85 prototype maker.
