Runway Excursions Examining the Dash 8's Landing Challenges - Landing Gear Challenges - Exploring the Dash 8's Vulnerability
The Dash 8 aircraft, operated by Ethiopian Airlines, has faced a concerning series of landing gear challenges leading to runway excursions.
In one incident, the left-hand landing gear of a Dash 8 Q400 collapsed during landing, causing the plane to veer off the runway.
Similar issues were reported with the Dash 8400 model, where the landing gear failed upon touchdown, resulting in substantial aircraft damage.
These incidents highlight the vulnerability of the Dash 8's landing gear system and the need for thorough investigation and potential design improvements to ensure the safety of passengers and crew.
While no injuries were reported, the recurring nature of these problems is worrying and warrants close scrutiny by aviation authorities and the manufacturer.
The Dash 8's landing gear system is designed with a complex hydraulic and mechanical mechanism, making it vulnerable to technical failures during landing.
The Dash 8 Q400 and Dash 8-400 models have experienced several incidents where the landing gear has collapsed or malfunctioned, leading to runway excursions, prop strikes, and substantial aircraft damage.
Flat tires on the Dash 8 are suspected to be a contributing factor in some of these landing gear incidents, potentially causing loss of control during the landing process.
The Dash 8's landing gear challenges have been a recurring issue, with similar incidents reported in the past, such as the Bombardier Dash 8 landing gear problem in May 2019 and the Dash 8 landing gear emergency landing challenge video uploaded to YouTube in December
The Dash 8's landing gear system requires precise operation and careful attention from pilots, as any malfunctions or issues during landing can lead to potentially dangerous situations, as evidenced by the incidents that have occurred.
The Dash 8's landing gear vulnerabilities highlight the need for ongoing research and engineering improvements to enhance the reliability and safety of this aircraft's landing systems, particularly in adverse weather conditions or challenging runway environments.

Runway Excursions Examining the Dash 8's Landing Challenges - Runway Excursions Uncovered - A Look at Recent Incidents
Runway excursions continue to be a significant safety concern in the aviation industry, with recent incidents highlighting the importance of addressing contributing factors such as unstable approaches, poor runway conditions, and pilot errors.
According to the International Civil Aviation Organization (ICAO), runway excursions involve a range of factors, including unstable approaches, poor runway conditions, and pilot errors, highlighting the complex nature of this issue.
A review of 141 runway excursion accidents involving commercial jet aircraft between 1998 and 2007 found that 120 accidents occurred during landing, resulting in 550 fatalities, underscoring the severity of these incidents.
The International Air Transport Association (IATA) reported that approximately 23% of accidents in its global accident database from 2005 to the first half of 2019 involved runway excursions, indicating the persistent challenge this phenomenon poses to the aviation industry.
The direct cost of runway excursion events in 2019 was estimated to be more than US$4 billion, demonstrating the significant financial impact these incidents can have on airlines and aviation stakeholders.
A study of accident data from 2013 to 2022 showed that there were 125 runway excursion (RE) accidents, with 98 occurring on passenger flights and 27 on cargo flights, highlighting the widespread nature of this problem across different aviation sectors.
In FY 2022, there were 7 RE accidents, resulting in a rate of 22 per million sectors, which is below the five-year (2018-2022) RE accident average rate of 27 per million sectors, suggesting potential improvements in runway excursion prevention efforts.
The Runway Excursion Risk Reduction (RERR) Toolkit found that there were almost 30 excursions per year for commercial aircraft, accounting for over 25% of all accidents, emphasizing the need for continued focus on this critical safety issue.
Runway Excursions Examining the Dash 8's Landing Challenges - Directional Control Dilemmas - A Contributing Factor to Consider
Loss of pilot directional control during landing is a common contributing factor to runway excursions.
Reports indicate it is one of the top risk factors, along with issues like rejected takeoffs, go-arounds not conducted, and landing gear malfunctions.
These factors can lead to dangerous runway excursions, which can result in accidents and incidents.
To mitigate the risk, operators should have clear policies on stabilized approaches and landings, and pilots should be aware of the challenges posed by contaminated runways.
Addressing directional control dilemmas is crucial in enhancing the safety of runway operations.
Studies have shown that loss of pilot directional control during landing is one of the top risk factors contributing to runway excursions, second only to rejected takeoff before V1.
Pilot disorientation and incorrect rudder inputs have been identified as common causes of directional control issues, particularly on slippery or contaminated runways.
The Dash 8's complex landing gear system, with its hydraulic and mechanical components, has been found to be more vulnerable to technical failures that can lead to loss of directional control during landing.
Flat tires on the Dash 8 have been suspected as a contributing factor in some landing gear incidents, potentially causing unexpected reactions and loss of control.
Dash 8 operators have reported similar landing gear challenges, such as the Dash 8-400 model experiencing landing gear failures upon touchdown, suggesting a systemic issue with the aircraft's design.
Adverse weather conditions, including crosswinds and reduced runway surface friction, can significantly exacerbate directional control problems, increasing the risk of runway excursions for the Dash
Investigators have found that the combination of multiple risk factors, such as an unstable approach and a landing gear malfunction, can create a synergistic effect, dramatically raising the likelihood of a runway excursion.
Aviation authorities and the Dash 8 manufacturer have been urged to closely examine the aircraft's landing gear design and provide clear guidance to operators on mitigating directional control challenges during Dash 8 landings.
Runway Excursions Examining the Dash 8's Landing Challenges - Short and Long Runways - No Environment Is Risk-Free
Runway excursions can occur on both short and long runways, as no environment is completely risk-free.
Studies have shown that factors like unstabilized approaches, pilot deviations from procedures, and external distractions can contribute to runway excursion incidents, even in varying runway length scenarios.
Researchers have proposed new frameworks to maximize risk-free throughput on runways, addressing the growing demand for takeoff and landing slots during peak travel periods.
Statistically, shorter runways have a higher risk of runway excursions, with overruns being more common on shorter runways and veer-offs more prevalent on longer runways.
Runway conditions, such as surface contamination, can significantly impact braking action and increase the likelihood of runway excursions, regardless of runway length.
The Dash 8 aircraft's high-wing design and relatively low ground clearance can make it more susceptible to runway excursions during cross-wind landings compared to lower-wing aircraft.
Pilots often struggle with the Dash 8's sensitive rudder controls, leading to increased workload and potential for directional control issues during landing on both short and long runways.
The Dash 8's landing gear design, with its complex hydraulic and mechanical components, has been identified as a contributing factor in several runway excursion incidents, highlighting the need for design improvements.
Dash 8 operators have reported a higher incidence of flat tires during landing, which can further exacerbate the aircraft's vulnerability to directional control problems and runway excursions.
Unstabilized approaches, a common factor in runway excursions, are more challenging to manage on short runways, where the margin for error is smaller compared to longer runways.
Runway surface conditions, such as rubber deposits or contamination, can reduce the effectiveness of braking systems, posing a greater threat to aircraft with higher landing speeds on longer runways.
Runway overruns on short runways can result in more severe consequences, as the aircraft is more likely to come to a stop off the runway surface, potentially causing greater damage and safety risks.
