A recent report has detailed the shocking reason why a 2023 Alaska Airlines flight skidded across the runway and produced sparks when it landed at a California airport.
The National Transportation Safety Board revealed in its final analysis that the terrifying landing was a result of ‘incorrect service/maintenance.’
The lack of maintenance to an essential part of the aircraft’s main landing gear had not taken place for nearly 800 flights — leading to a crack and eventual failure upon landing.
Passengers aboard Alaska Airlines Flight 1288 on a Boeing 737 filmed the terrifying moments the plane landed at John Wayne-Orange County Airport in Santa Ana on August 20, 2023.
Passengers on the flight had departed from Seattle, Washington, and landed in California around 11:15 pm during Tropical Storm Hillary.
Video footage of the landing revealed sparks flying in the air. The captain said the touchdown had a ‘film jolt feeling’ and confessed the plane was ‘pulling reasonably hard to the left,’ according to the NTSB report.
‘At Alaska Airlines, safety is our top priority. We appreciate the NTSB’s diligence in this investigation, and we are thankful to our crew members who safely operated this flight,’ Alaska Airlines said in a statement to DailyMail.com on the recent report.
The report revealed that the cause of the unusual landing was the failure of an aft trunnion pin, an important part of the aircraft’s main landing gear.

Passengers on board the flight were evacuated after sparks flew while the plane skidded down the runway
The pin connects the part of the plane that absorbs a landing with its wing. During the Alaska Airlines flight, the trunnion pin failed, resulting in the plane skidding down the runway and sparks on the tarmac.
The NTSB’s investigation found that the pin’s fracture was present for over 797 landing cycles before the jarring landing on August 20.
The crack likely developed in 2018 from excessive grinding due to heat exposure during a maintenance overhaul, according to the report.
‘However, results of this examination and previous NTSB investigations demonstrate that even relatively mild heat exposure from grinding and/or machining during overhaul can lead to cracking, which can lead to fatigue crack growth and failed landing gear components, as occurred in this accident,’ the report stated.
The NTSB noted that the crack wouldn’t have been visible before it fractured during the flight.
The report added that cracks can occur due to mild heat exposure from grinding, which can often go undetected.
The crack had reached a depth of 0.144 inches, which was large enough to cause a fracture in the trunnion pin, resulting in the collapse of the aircraft’s left main landing gear.
The crack likely occurred in 2018 from excessive grinding due to heat exposure, but had gone unnoticed until 2023
The pilot still landed the plane, and all 112 passengers were evacuated safely with no reported injuries or fatalities
Despite the rough landing, the pilot managed to land the plane and all 112 passengers safely evacuated with no deaths or reported injuries.
The flight was also met with rain, wind, and turbulence from Tropical Storm Hilary, which reached category four hurricane status as it ravaged the west coast of Mexico.
Hilary was downgraded to a tropical storm for parts of Southern California. It marked the first tropical storm warning in the region since Hurricane Nora in 1997, according to hurricane data from the National Oceanic and Atmospheric Administration.
The crew on Flight 1288 still could see the runway and noted that the landing gear indicator lights were green before the pilot descended.
As the plane hit the runway, passengers noticed the sparks, with one telling ABC News she was ‘panicking.’
‘I stood up and saw that my left side of the plane was tilted up and the right side plane was tilted down,’ another passenger told the outlet at the time.
The Orange County Fire Department responded to help evacuate passengers from the tarmac during the storm.
