A radar equipment malfunction identified by the Federal Aviation Administration on September 20 caused flight delays at both Newark Liberty International Airport and LaGuardia Airport. The technical issue, reported early in the morning, prompted immediate safety checks and required the rerouting of aircraft until the system could be verified as operational.
Airlines operating out of the two airports responded by adjusting schedules and holding planes on the ground while the FAA conducted inspections of the radar hardware. The malfunction affected the ability to track aircraft in the terminal airspace, a critical component for maintaining safe separation and efficient flow of traffic. As a result, several departures were postponed, and arriving flights were held in holding patterns until clearance could be safely issued.
The FAA coordinated with airport operations and airline dispatch teams to implement contingency procedures. These procedures included increased reliance on secondary surveillance systems and manual position reporting by pilots, measures designed to maintain safety while the primary radar system was offline. Technicians worked throughout the day to diagnose the fault and restore full functionality.
Both Newark and LaGuardia resumed normal operations after the radar equipment was repaired and revalidated. The incident underscored the dependence of busy metropolitan airports on reliable radar infrastructure and highlighted the protocols in place to manage unexpected equipment failures without compromising passenger safety.
Airlines advised travelers to monitor flight status updates and to expect possible further adjustments as the airports completed post‑incident reviews. The FAA indicated that a thorough investigation would follow to determine the root cause of the glitch and to prevent similar occurrences in the future.
