Older regional planes must now follow stricter safety rules
What happened
The US aviation agency is making maintenance rules stricter for certain regional airplanes. Operators of these planes must update their maintenance plans to meet new safety limits.
Why it matters
Airlines that fly ATR42-500 planes now face higher maintenance costs. This ensures these older planes continue to meet current safety standards, but it means more work for their operators.
The signal
Watch for any reports of these specific plane models being grounded due to non-compliance, or increased operational costs for airlines that fly them.
