United Express Jet Returns After Cockpit Windshield Shatters
A United Express regional jet made an emergency landing in Houston after its cockpit windshield shattered, sending glass into the flight deck.
A United Express regional flight with 72 people aboard made an emergency return to Houston on Sunday after its cockpit windshield shattered shortly after takeoff. The Embraer E175, operated by Mesa Airlines as flight UA6309 from Houston to El Paso, landed safely back at George Bush Intercontinental Airport approximately 35 minutes after departure.
No injuries were reported, and there was no depressurization of the aircraft. The Houston Fire Department responded to the distress call and later cleared the plane as safe. Passengers were transferred to a replacement aircraft, which subsequently landed in El Paso at 3:14 p.m.
Emergency Response and Investigation
The incident occurred shortly after the jet departed Houston around 12:20 p.m. The pilots stopped their climb at about 13,000 feet and slowed the aircraft after reporting glass falling into the cockpit. In a radio transmission, a crew member stated, "We just had our glass break. We’ll declare an emergency, sir."
The Federal Aviation Administration confirmed it will investigate the failure. The agency noted that airplane windshields are composed of multiple layers of tempered glass and other materials. A Mesa Airlines spokesperson said the first officer's windshield shattered and that returning to the airport is standard procedure in such cases, even without depressurization.
Potential Causes and Historical Precedents
While the cause remains unknown and under investigation, past incidents provide context for such failures. Investigators have previously identified issues like improper installation, the use of incorrectly sized bolts, or electrical faults in the anti-ice heating systems as potential causes.
Notable historical incidents involving cockpit windshield failure include:
| Incident | Year | Aircraft | Key Detail |
|---|---|---|---|
| Sichuan Airlines Flight 8633 | 2018 | Airbus A319 | Cockpit windshield shattered at 32,000 feet; manufacturing defect cited. |
| Frontier Airlines Incident | 2015 | Airbus A319 | Crew observed arcing and sparks before cracks spread across the glass. |
| Private Jet near Fiji | 2013 | Cessna 750 Citation X | Windshield failed while flying at 45,000 feet. |
| British Airways Flight 5390 | 1990 | BAC One-Eleven | Captain partially sucked out after incorrect bolts caused a windshield blowout at 17,300 feet. |
In the 1990 British Airways case, a maintenance error where technicians used bolts that were both too thin and too short led to a catastrophic failure under cabin pressure. The captain survived severe injuries.
Aftermath and Industry Procedures
The involved aircraft, tail number N87360, remained at the Houston airport awaiting inspection and maintenance. Findings from the FAA investigation, which may also involve the National Transportation Safety Board, are expected to take weeks or months. Given the limited scope of this mishap, the process could be relatively swift. The safe outcome shows the effectiveness of crew training and standard emergency protocols for such technical failures.
