Boeing 737 MAX fuel tanks may have the wrong nuts, requiring inspections
What happened
The US aviation regulator proposes a new rule for certain Boeing 737 MAX airplanes. It requires airlines to inspect fuel tanks for incorrectly installed parts.
Why it matters
This is a small, specific safety fix. It means airlines will have to ground some planes for inspections, which costs money and time. The issue is about basic manufacturing quality control, not a design flaw.
The signal
Watch for how many planes are affected and if this leads to any flight cancellations or delays.
