Older regional airplanes need new safety checks for their maintenance programs

The US aviation regulator wants to update safety rules for certain regional airplanes. This means airlines operating these planes will have to change their maintenance schedules to include new or stricter checks.

Airworthiness directives are how regulators ensure older aircraft remain safe as they age. This proposed change means that the type of regional planes used for decades will now have to meet updated safety standards. It forces operators to re-evaluate their maintenance programs, which can be a significant cost and logistical challenge.
