Airlines must fix a specific engine part on some GE jet engines
What happened
The US aviation regulator is ordering airlines to inspect and repair certain General Electric jet engines. This is because a specific internal part, called a support air duct, has been failing during engine disassembly.
Why it matters
This is a routine safety directive. It means airlines will have to ground planes with these engines for inspection and repair, which costs money and time. The goal is to prevent engine failures during flight, which could be catastrophic.
The signal
Watch for any reports of these specific engine parts failing in flight, which would indicate the fix was not sufficient.
