Question · Q3 2025
Ronald Jay Epstein inquired about the specific factors driving the recent reevaluation and delay of the 777X program, particularly concerning the certification process and TIA approvals.
Answer
President and CEO Dave Calhoun explained that the delay is solely due to challenges in completing certification work, specifically obtaining TIA (Type Inspection Authorization) approvals, not new issues with the airplane or engines. He admitted underestimating the effort required for TIA approvals and FAA data review, describing the slowdown as a collective learning experience for Boeing and the FAA with the new process.
