Boeing 787 Dreamliner Fleet Faces New Repetitive Inspection Requirement
The Boeing 787 Dreamliner fleet is facing a new regulatory requirement for repetitive inspections due to structural issues related to early manufacturing methods. The Federal Aviation Administration (FAA) has issued Airworthiness Directive 2026-17-02, which makes it mandatory for operators to conduct ultrasonic and detailed visual inspections of primary wing splice joints on certain aircraft.
The issue stems from excessive shim gaps and high pull-up forces during wing assembly in early production years. If left unmonitored, these stresses can seed fatigue cracks in wing structures, potentially compromising their ability to carry limit loads. Boeing identified the outdated shim measurement process in 2019 and revised factory assembly protocols.
The directive targets 17 US-registered aircraft and between 77 and 94 airframes globally, with early-production 787-8s making up most affected airframes. The requirements bulletin encompasses 49 787-8s, 27 787-9s, and one 787-10 worldwide.
