Qatar Airways Boeing 777-300ER Cracked Windshield Incident
A Qatar Airways Boeing 777-300ER, operating flight QR-853 from Kuala Lumpur to Doha, had to make an unscheduled landing at Kempegowda International Airport in Bengaluru after the cockpit crew discovered a cracked windshield during flight.
Details of the Diversion
Pilots followed safety procedures and communicated with air traffic control to coordinate an emergency diversion to Bengaluru. The aircraft, registered as A7-BAC, landed safely with emergency services on standby.
Qatar Airways Fleet
- Qatar Airways operates one of the largest Boeing 777-300ER fleets.
- The fleet consists of 57 aircraft with an average age of 12.4 years.
- The specific aircraft involved was 17.2 years old, delivered in August 2008.
Flight and Landing Details
According to available flight data, QR-853 departed Kuala Lumpur at 8:22 PM local time on September 22. The flight proceeded as planned, reaching a cruising altitude of FL360. About 100 nautical miles northeast of Bangalore, the decision to divert was made, and the aircraft landed safely on runway 27L approximately 30 minutes later.
Previous Incidents
The same aircraft had a minor incident on September 15, 2015, when it struck runway lights during takeoff at Miami International Airport.
Importance of Windshield Integrity
A cracked windshield can lead to serious structural issues if not addressed. Aircraft cockpit windows consist of multiple thick glass layers with plastic or acrylic sheets to provide heating. These layers are designed to withstand pressure individually. Despite their robustness, pilots maintain the authority to divert if safety concerns arise.
Conclusion
Aircraft windshields may crack due to factors like stress, temperature changes, or material fatigue. Although regular maintenance and inspections are in place to detect such issues early, in-flight occurrences cannot be completely prevented.
