Boeing still needs FAA approval for more 777-9 flight tests: CEO

Boeing acknowledges that the Federal Aviation Administration (FAA) requires a redesigned engine seal before proceeding with further flight testing of the 777-9 aircraft. The company states it currently lacks the necessary approvals to complete significant portions of the jet’s flight test program, despite aiming to commence deliveries in early 2027. Boeing maintains its commitment to beginning delivery operations next year for the long-delayed widebody jet. This delay is directly linked to the FAA's pending approval regarding the updated engine seal design. Consequently, additional flight tests are contingent upon receiving this crucial certification from the regulatory body.
