Boeing MD-11 cargo planes must be inspected for engine detachment after an accident
What happened
The US aviation regulator is ordering inspections for all Boeing MD-11 and MD-11F airplanes. This means operators cannot fly these planes until they are checked for engine pylon issues and any necessary repairs are made.
Why it matters
An engine falling off a plane during takeoff is a serious problem. This rule means that every MD-11 cargo plane must be grounded and inspected. It forces operators to address a specific, dangerous defect before any more flights.
The signal
Watch for how many planes are found with defects and how long it takes for the global fleet of MD-11s to complete these inspections and return to service.
