Older ATR airplanes need new wiring to fix a speed sensor problem

The US aviation regulator proposes a new rule for certain ATR-GIE Avions de Transport Régional airplanes. These planes need new wiring and relays to fix a problem with their speed monitoring system.

This is a routine safety fix for a specific type of aircraft. It means that the planes will be safer to fly, as a known issue with their speed monitoring will be addressed. Airlines operating these models will need to schedule maintenance to install the required parts.
