Understanding Wildlife Strikes in Aviation

Wildlife strikes, while relatively rare in terms of their frequency compared to the total number of flights, represent a persistent and serious safety concern in aviation. These incidents involve an aircraft colliding with an animal, typically birds, but occasionally mammals like deer, coyotes, or even smaller creatures, during takeoff, landing, or low-altitude flight. The coyote strike United Airlines flight 1727 at O'Hare is a prime example of a mammalian strike, which, while less common than bird strikes, can be equally, if not more, damaging due to the animal's mass and density.

Data from aviation authorities like the FAA (Federal Aviation Administration) and NTSB (National Transportation Safety Board) consistently show that wildlife strikes occur worldwide, with varying degrees of severity. Most strikes result in minor or no damage to the aircraft, but a significant portion can cause substantial damage, leading to costly repairs, flight delays, and, in rare instances, emergency landings or even accidents. The risks are highest during takeoff and landing phases, as aircraft are at lower altitudes and higher speeds, making evasive maneuvers difficult.

Common Wildlife Threats and Their Impact

Birds, particularly larger species like geese, gulls, and raptors, account for the vast majority of wildlife strikes. Their ability to fly and congregate in large numbers near airports makes them a constant threat. Bird strikes can cause damage to engines, wings, fuselage, and windshields. Engine ingestion, where birds are sucked into jet engines, is particularly dangerous, as it can lead to engine failure, as famously seen in the "Miracle on the Hudson" incident.

Mammalian strikes, like the coyote strike United Airlines flight, are less frequent but can be equally impactful. Animals like deer, coyotes, and even rabbits can wander onto runways, especially at airports located near natural habitats. The impact of a large mammal can cause significant structural damage to landing gear, tires, and even the aircraft's underbelly. Unlike birds, which can be dispersed by noise or visual deterrents, mammals often require more robust physical barriers or active removal strategies.

Beyond the immediate mechanical damage, wildlife strikes can also lead to secondary issues such as hydraulic leaks, electrical system malfunctions, and even fires. The debris from a strike can also pose a hazard to other aircraft or ground vehicles. This complexity necessitates a multi-layered approach to wildlife management at airports, combining habitat modification, active dispersal techniques, and continuous monitoring to minimize risks.

O'Hare International Airport's Wildlife Management Protocols

Chicago O'Hare International Airport, like all major airports, operates under stringent wildlife management protocols designed to mitigate the risk of incidents like the coyote strike United Airlines flight. Given its vast size and proximity to natural habitats, O'Hare employs a dedicated team of wildlife biologists and specialists. Their primary goal is to make the airport environment less attractive to wildlife and to safely remove animals that do venture onto the property.

Key strategies employed at O'Hare include:

  • Habitat Modification: This involves managing vegetation, water sources, and food availability on airport grounds to deter wildlife. For example, tall grasses that provide cover for animals might be mowed, and standing water that attracts birds might be drained.
  • Fencing and Barriers: Robust fencing systems are critical to prevent larger mammals like coyotes and deer from accessing the runways and taxiways. Regular inspections ensure these barriers remain intact.
  • Active Dispersal Techniques: Wildlife control teams use a variety of methods to scare away animals, including pyrotechnics (bangers and screamers), propane cannons, distress calls, and even trained dogs.
  • Trapping and Relocation: For persistent or problematic animals, humane trapping and relocation might be employed, though this is often a last resort for species that pose a significant threat.
  • Monitoring and Reporting: Airport personnel, including air traffic controllers and pilots, are trained to report wildlife sightings immediately. This data helps in identifying high-risk areas and times, allowing for more targeted intervention.
  • Education and Training: Continuous training for airport staff on wildlife hazards and response procedures is essential to maintain a high level of preparedness.

Despite these comprehensive measures, wildlife is inherently unpredictable. The O'Hare coyote strike United Airlines flight serves as a rare but potent reminder that even the most advanced protocols cannot eliminate all risks, underscoring the need for constant vigilance and adaptation.

The Role of Aircraft Design and Safety Features

Beyond airport-level management, aircraft design itself plays a crucial role in mitigating the impact of wildlife strikes. Modern commercial aircraft, including the Boeing 737 MAX 9 involved in the coyote strike United Airlines flight, are built to withstand significant forces and are subjected to rigorous testing to ensure their resilience against various hazards, including bird and other wildlife impacts.

Key design considerations and safety features include:

  • Engine Design: Aircraft engines are designed to be "bird-proof" to a certain extent. They undergo certification tests where they must demonstrate the ability to ingest certain sizes and numbers of birds without catastrophic failure, or at least to allow for a safe shutdown. While a coyote strike on the landing gear is different from an engine ingestion, the overall philosophy of robust design applies.
  • Landing Gear Strength: The landing gear, which took the brunt of the impact in the United Airlines coyote incident, is engineered to withstand immense forces during takeoff and landing, including uneven terrain and hard landings. This inherent strength provides a degree of protection against wildlife impacts on the runway.
  • Structural Integrity: The aircraft's fuselage, wings, and control surfaces are designed with redundancies and robust materials to absorb impacts and prevent widespread structural failure.
  • Redundant Systems: Modern aircraft feature multiple, independent systems for critical functions like hydraulics, electrical power, and flight controls. If one system is compromised by a strike, others can take over, allowing the crew to maintain control and safely land the aircraft.
  • Advanced Avionics and Monitoring: Pilots have access to sophisticated instrumentation that provides real-time data on the aircraft's systems. This allows them to quickly identify anomalies, such as damage to the landing gear or unusual vibrations, enabling them to make informed decisions like declaring an emergency and returning to the airport.

These design principles, coupled with strict maintenance schedules and pre-flight inspections, form the backbone of aviation safety, ensuring that aircraft can often withstand and recover from unexpected events like the O'Hare coyote strike.

Regulatory Oversight and Incident Reporting (FAA, NTSB)

The aviation industry operates under the strict oversight of regulatory bodies like the Federal Aviation Administration (FAA) in the United States and international organizations such as the International Civil Aviation Organization (ICAO). These bodies establish and enforce safety standards, certify aircraft, and regulate airport operations. The coyote strike United Airlines flight falls squarely within their purview, triggering established protocols for reporting and investigation.

When a wildlife strike occurs, airlines and airports are required to report it to the FAA. This data is crucial for understanding trends, identifying high-risk areas, and developing more effective mitigation strategies. The National Transportation Safety Board (NTSB) may also become involved, particularly if an incident results in significant damage, injury, or raises broader safety concerns. Their role is to investigate accidents and incidents to determine probable cause and issue safety recommendations to prevent similar occurrences in the future.

Lessons from Past Incidents: Boeing 737 MAX and Bird Strikes

The aviation industry continuously learns from past incidents, whether they involve mechanical failures, human error, or environmental factors like wildlife strikes. For example, the NTSB urges quick fix on Boeing plane engines to prevent smoke from filling cabin after a bird strike. Safety experts recommend that the engines on Boeing’s troubled 737 MAX undergo specific modifications. While this particular recommendation relates to bird strikes and engine issues, it illustrates the ongoing process of identifying vulnerabilities and implementing solutions across various aircraft types, including the Boeing 737 MAX 9 involved in the United Airlines coyote incident.

Another notable example is a past incident where a commercial flight carrying 159 people had a major scare as it took off from Denver International Airport. The United Airlines flight struck an animal, which crippled one of its components, demonstrating that such events are not isolated. These incidents, while concerning, contribute to a vast database of knowledge that informs aircraft design improvements, pilot training, and airport wildlife management practices. Each reported coyote strike United Airlines flight or bird strike becomes a data point, helping to refine safety protocols and make air travel even safer.

Passenger Experience and Airline Communication
