Boeing MD-11 cargo planes must get new wiring inspections after a mid-air engine failure
What happened
The US aviation regulator is ordering new inspections for certain Boeing MD-11 and MD-11F cargo planes. This is because one of these planes had an engine thrust reverser deploy by itself during a flight at low altitude.
Why it matters
A thrust reverser deploying in flight can cause a plane to lose control. This new rule means operators of these specific Boeing cargo planes must regularly check the wiring that controls these systems. It aims to prevent a rare but dangerous mechanical failure from happening again.
The signal
Watch for reports of these inspections finding widespread wiring issues, or if similar uncommanded deployments occur on other aircraft types.
