Yesterday morning, an Alaska Airlines Boeing 737 returned to Seattle shortly after it departed from the Pacific Northwest air hub. An unusual vibration on the side of the aircraft was cited as a factor in this decision, with footage circulating on social media also showing that some of the twinjet’s left engine cowling came loose.

Not the longest flight

According to Fox, the service in question was bound for San Diego, California. However, a quick look at tracking data from FlightRadar24.com shows that the flight only got as far south as Mount Rainier before turning back towards its departure airport. As already established, an ‘unusual vibration’ prompted the diversion.

SIMPLEFLYING VIDEO OF THE DAY

While returning to a flight’s departure airport is a fairly standard procedure under such circumstances, things took a slightly more dramatic turn upon arrival back in Seattle. Indeed, multiple passengers on the flight, which only managed to climb as high as 12,975 feet and was in the air for just 27 minutes, shared striking footage.

As seen in the tweet above, these clips showed part of the 737’s left-hand engine cowling coming loose, before eventually tearing off as the aircraft slowed down on Seattle’s 3,627-meter-long runway 16L. This concrete-paved strip was then briefly closed to allow the associated debris to be swept clear of the path of other aircraft.

Second time lucky

Despite the dramatic nature of the footage that has emerged of the incident, no harm came to anyone onboard the Alaska Airlines flight AS558. Once safely on the ground, the affected aircraft was taken out of service, with a replacement being sourced to allow the passengers to continue their journey to San Diego as planned.

The flight’s scheduled departure time yesterday was 07:25, with its arrival in southern California planned to take place just under three hours later at 10:19. Data from FlightRadar24 suggests that the replacement aircraft eventually took to the skies at 11:10, arriving just over three hours behind schedule at 13:22. Simple Flying contacted Alaska Airlines, with a spokesperson confirming in summary that:

“Alaska Airlines Flight 558 from Seattle to San Diego on Monday morning reported an unusual vibration on the left side of the aircraft soon after departure. The aircraft returned to the airport and landed safely. Part of the metal paneling that covers the engine, called the cowling, detached from the aircraft when it landed. “
