It mandates detailed internal and external inspections of the forward pressure bulkhead to identify any damage caused by reported nonconformances such as excessive gaps and pull-up. The directive aims to prevent fatigue cracks that could compromise the structural integrity of these aircraft.
What Changed
This new airworthiness directive introduces mandatory inspections of the forward pressure bulkhead on specified Boeing 787 models. It requires operators to perform detailed inspections and apply on-condition corrective actions if damage is found. The directive also corrects a typographical error regarding the ATA code and clarifies optional steps in the inspection process.
Why It Matters
This directive is critical for aviation professionals as it addresses a potential structural safety risk that could lead to undetected fatigue cracks in the forward pressure bulkhead. Compliance ensures the continued airworthiness and safety of affected Boeing 787 aircraft, helping operators and maintenance teams prevent structural failures. It also clarifies inspection procedures and reporting requirements, aiding in regulatory compliance and operational planning.
What To Do
Operators of Boeing 787-8, 787-9, and 787-10 airplanes must conduct detailed internal and external inspections of the forward pressure bulkhead by January 13, 2026.
