Dassault Falcon jets must check their navigation antennas after incorrect installations

The US aviation regulator is requiring inspections and potential reinstallation of navigation antennas on certain Dassault Falcon 2000EX airplanes. This means these planes now have an operational limit for certain low-visibility landings until the antenna is checked.

A small part installed incorrectly can have big consequences, especially in aviation. This rule means pilots cannot rely on automated landing systems in bad weather until a specific antenna is verified. It's a reminder that even routine maintenance can introduce critical safety issues.
