Windshield SHATTERS After Takeoff Learjet Makes Emergency Landing

On August 5, 2026, Flightstar Corp Flight FSR816, a Bombardier Learjet 75 registered FSR816, departed New York John F. Kennedy International Airport when the crew declared a Mayday after the right windshield suddenly shattered. The aircraft was climbing through approximately 7,000 feet when the crew reported the failure. They ruled out a bird strike, requested an immediate diversion and landed safely at Westchester County Airport with seven people aboard.

Windshield failure

The aircraft had only recently departed JFK when the crew reported a loud event and discovered that the right windshield had shattered. The damaged windshield produced wind noise and buffeting and made cockpit communications more difficult, but the crew retained control of the aircraft.

The crew told ATC that there had been no bird strike. They reported seven people aboard and about 4,580 pounds of fuel remaining, then requested a diversion to Westchester County Airport.

Approach to Westchester

Controllers prioritized the Mayday and issued vectors and descent instructions toward HPN. The crew was guided for an RNAV Runway 34 approach while surrounding traffic was coordinated around the emergency aircraft.

The damaged windshield did not prevent the crew from maintaining control during the diversion. The aircraft completed the approach and landed safely at Westchester.

Cause not established

The public incident record does not identify what caused the windshield to shatter. The event is therefore described as a sudden windshield failure of undetermined cause. No manufacturing defect, impact damage or thermal-stress mechanism has been established in the record.

Managing the windshield failure

The incident record states that the right windshield failure occurred shortly after departure and produced significant noise and vibration in the cockpit. The crew retained control, notified ATC and requested priority handling for Westchester. The emergency was therefore managed as a controlled diversion rather than an uncontrolled loss of the aircraft.
