Enugu Air Accident Exposes Wider Aviation Safety Gaps

The Enugu Air accident at Benin Airport has raised wider safety concerns involving runway conditions, weather and airport infrastructure.

Enugu Air was involved in the accident on July 23 when its Embraer ERJ 170-100LR, registered as 5N-ENR, was involved in an occurrence at Benin Airport.

The Nigerian Safety Investigation Bureau (NSIB) released its preliminary report on August 21.

Under Annex 13 to the Convention on International Civil Aviation, accident investigations aim to prevent future accidents and incidents rather than establish blame or liability.

The NSIB investigation should therefore not be treated as an attempt to blame Enugu Air or its crew. Its main purpose is to establish what happened, identify weakened safety barriers and determine how similar events can be prevented.

The preliminary findings point to several factors, including weather conditions, runway conditions, landing performance, an unserviceable autobrake system, runway selection, airport infrastructure and access to operational information.

The flight from Lagos was reportedly normal. The aircraft was certified, while the crew held the required licences and qualifications. Nothing in the preliminary findings immediately suggested a basic problem with pilot training or aircraft airworthiness.

That finding is important because it would be premature to describe the Enugu Air accident simply as a case of pilot incompetence or an unairworthy aircraft.

The seriousness of the accident, however, remains clear. The aircraft struck approach-lighting equipment, overran the runway, collided with fixed concrete structures and lost its landing-gear assemblies. The absence of fatalities does not make the occurrence less serious.

The report also draws attention to the aircraft’s touchdown point and the runway distance available after landing. Touching down further along a runway can reduce the stopping distance available, especially when other risks such as a wet runway, tailwind and manual braking are present.

Weather conditions also played an important role. The NSIB found that conditions at Benin were deteriorating, with rain and reduced visibility around the airport. The crew had also received information about the changing weather.

Benin Tower reportedly advised the crew that the approach to Runway 23 appeared more favourable than Runway 05. Despite this information, the crew continued with the RNAV approach to Runway 05.

Another factor was the aircraft’s autobrake system, which was not serviceable. The crew knew about the condition and planned to rely on manual braking. Manual braking remains an accepted way of stopping an aircraft, so the faulty autobrake system alone did not necessarily make the landing unsafe.

However, the accident shows the danger that can emerge when several manageable risks occur at the same time.

The safety concerns extend beyond the aircraft and its crew. They include the quality of weather information, runway conditions, tower visibility and the physical environment around the runway.

The NSIB preliminary report has made safety recommendations to the NCAA, FAAN and NiMet. The key issue now is whether those recommendations will lead to measurable action.

The NCAA should require clear corrective measures, deadlines and evidence that the recommendations have been implemented.

FAAN should also carry out a nationwide review of abandoned, redundant and potentially dangerous structures around airports, especially areas beyond runway ends.

NAMA should examine tower visibility at airports where controllers rely heavily on direct visual observation. NiMet, meanwhile, should review the reliability and backup capacity of operational weather-information systems.

The aviation industry should also take a broader look at how runway conditions are reported and communicated.

The main lesson from the Enugu Air accident is that aviation safety depends on several barriers working together. When a number of those barriers become weaker at the same time, the margin for error can become very small.

The July 23 incident should therefore serve as a warning to the wider aviation sector, not just the airline or its crew.

The fact that no lives were lost provides an opportunity to learn from the incident and strengthen safety measures before another aircraft faces similar conditions.

The real test now is whether the findings will result in practical changes that make Benin and other Nigerian airports safer.

Do you think the NSIB recommendations should lead to a nationwide review of safety standards at Nigerian airports?
