NTSB: Bird Strike Caused Alaska Cargo A330 Engine Failure Over Cincinnati

The National Transportation Safety Board (NTSB) has released a preliminary report confirming that a bird strike caused the left-engine failure and subsequent cockpit smoke alert on an Alaska Airlines cargo flight in January. The incident involved an Airbus A330-343 and necessitated an emergency return to Cincinnati/Northern Kentucky International Airport (CVG) shortly after takeoff.

The event underscores the persistent and significant threat that wildlife, particularly birds, poses to aviation operations, especially during the critical takeoff and landing phases. According to the Federal Aviation Administration (FAA), over 13,000 bird strikes are reported annually in the United States alone, highlighting the frequency of such occurrences. This incident serves as a case study in both the potential for severe damage from wildlife encounters and the effectiveness of crew training in managing complex in-flight emergencies.

Incident Details from NTSB Report

According to the NTSB's preliminary report, DCA26LA106, the incident occurred on January 28, 2026, at approximately 3:05 p.m. Eastern Standard Time. The aircraft, registration N5827K, was operating as Alaska Airlines Flight 2616, a domestic cargo flight for Amazon.com Services LLC. The flight was conducted under Instrument Flight Rules (IFR) as a Title 14 Code of Federal Regulations Part 121 operation.

The two-person flight crew reported that during the initial climb out of CVG, at an altitude between 900 and 1,000 feet, they heard a loud bang followed by a jolt. Immediately after, the aircraft's Electronic Centralized Aircraft Monitor (ECAM) displayed an "ENG 1 FAIL" warning, indicating a failure of the left engine. The crew initiated the appropriate emergency checklist procedures to secure the engine.

Shortly after addressing the engine failure, the flight crew observed smoke in the cockpit and received a secondary ECAM alert for "MD (main deck) SMOKE." In response to the dual emergency, the crew declared an emergency with air traffic control and initiated an immediate return to CVG. The aircraft landed safely without further incident, and neither of the two pilots was injured. A post-landing inspection revealed what the NTSB classified as "substantial" damage to the aircraft. Investigators recovered the remains of eight Canada geese from the runway area, confirming the cause of the engine event.

The Broader Context of Wildlife Strikes

Bird and other wildlife strikes represent a significant financial and safety challenge for the global aviation industry. Research from the UK's Central Science Laboratory estimates that these incidents cost airlines approximately US$1.2 billion annually worldwide through aircraft damage and operational delays. The FAA has also noted a concerning trend, reporting a 14% increase in wildlife strikes in the U.S. between 2023 and 2024.

The vast majority of these events, around 90%, occur at low altitudes in the vicinity of airports during takeoff or landing. This is the phase of flight where aircraft and dense bird populations are most likely to share the same airspace. Bird ingestion into a jet engine is a primary hazard, capable of causing extensive damage to fan blades, which can lead to a loss of thrust or, in severe cases, a catastrophic and uncontained engine failure.

Airports worldwide implement comprehensive Wildlife Hazard Management programs to mitigate these risks. These programs often involve habitat modification to make the airport environment less attractive to wildlife, as well as active dispersal techniques using pyrotechnics, trained falcons, or other methods. However, as the Alaska Airlines incident demonstrates, these measures can reduce but not entirely eliminate the risk of a strike.

Next Steps in the Investigation

The information released by the NTSB is preliminary and subject to change as the investigation continues. The agency's investigators will now conduct a more detailed examination of the damaged engine, the aircraft's flight data recorder, and the cockpit voice recorder. Further analysis will focus on the performance of the engine following the bird ingestion and the crew's response to the emergency.

A final report, which typically takes 12 to 24 months to complete, will provide a detailed analysis of the incident, a determination of the probable cause, and may include safety recommendations aimed at preventing similar occurrences in the future. These recommendations could be directed at aircraft manufacturers, airlines, or regulatory bodies like the FAA.

Why This Matters

This incident is a critical reminder of the unavoidable operational risks present in daily aviation. It highlights the vulnerability of even modern, wide-body aircraft to wildlife strikes and reinforces the importance of rigorous crew training in handling multiple, cascading in-flight emergencies. For airport operators and safety regulators, it emphasizes the ongoing need to evolve and enhance wildlife management strategies to protect aircraft during their most vulnerable phases of flight.
