United Airlines is replacing engines on two Boeing 737NGs after finding parts from AOG Technics, a supplier alleged to have falsified certification documents.
Boeing-recommended 777 structural inspections backed by inaccurate maintenance instructions may force affected operators to act quickly to undo any damage.
Maintenance info used by regulators to mandate 777 structural inspections includes errors that may create more risks for affected aircraft than it addresses.
Boeing needs more time to validate the risks of mechanics inadvertently leaving nacelle access doors unlatched and develop ways to prevent that from happening.
The aircraft-maker has finished its proposed redesign of older 737 nacelles, but it must analyze maintenance-related errors to help mitigate their risk.
