The aircraft involved in the collision in southwestern South Korea, operated by Jeju Air, was a Boeing 737-800, an aircraft type that sees extensive global deployment.
Of the roughly 28,000 commercial aircraft currently operating worldwide, according to aviation data firm Cirium, approximately 15 percent, or 4,400 units, are Boeing 737-800s. This model is part of Boeing's Next-Generation 737 series, which preceded the newer 737 Max – an aircraft that faced worldwide grounding following two deadly accidents over five years ago.
Cirium data shows nearly 200 carriers utilize the 737-800, with five South Korean airlines among them: Jeju Air, T'way Air, Jin Air, Eastar Jet and Korean Air. The aircraft enjoys widespread use across Asia, Europe and North America, with Boeing having delivered approximately 5,000 units since its 1998 introduction.
"This particular aircraft model demonstrates exceptional safety characteristics and maintains an impressive safety record," noted Najmedin Meshkati, an engineering professor at the University of Southern California specializing in Boeing 737 series safety research.
The global 737-800 fleet ranges from 5 to over 27 years in age. Commercial aircraft, when properly maintained, can remain operational for 20 to 30 years or beyond. According to Flightradar24, a flight tracking platform, the incident aircraft was 15 years old. Initially operated by Europe's Ryanair, the aircraft transferred to Jeju Air in 2017 through a lease agreement with SMBC Aviation Capital, Cirium reports.
Authorities have launched an investigation into the incident's cause, including examining whether avian interference contributed to landing gear complications.
Boeing issued a statement Sunday confirming their communication with Jeju Air and readiness to provide assistance.
Aviation frequently encounters bird strikes, which occasionally result in windshield damage. Various airports employ falconry and other bird deterrent strategies. Muan International Airport, the incident location, implements bird dispersal techniques including distress call broadcasts and culling measures, according to Korean Office of Civil Aviation documentation.
Meshkati emphasized that while the 737-800's landing gear features robust design and proven reliability, inadequate maintenance could compromise deployment functionality. "Maintenance deficiencies frequently contribute significantly to aviation incidents," he explained.
However, Meshkati and fellow aviation specialists advise against premature conclusions regarding such events. Incident investigations typically reveal multiple contributing factors, often requiring years of thorough analysis to fully understand.
