Some jet engines will need new inspections and parts to prevent stalls

The US aviation regulator is proposing new rules for certain CFM International LEAP-1A engines. These rules would require airlines to perform new calculations and inspections, and replace specific parts, to prevent engine stalls.

Engine stalls during takeoff or in the air are rare but dangerous. This proposed rule means airlines will have to spend money on new maintenance and parts for a specific type of engine. It aims to prevent a known issue from becoming a widespread problem.
