Allegiant A319 Suffers Engine Failure During Go-Around at Mesa

The engine failed at the most demanding point of the approach

Allegiant Air Flight G4-175 was approaching Mesa Phoenix Gateway Airport when the crew initiated a go-around in gusty conditions. During the maneuver, the right engine suffered a severe failure at very low altitude. Reports described loud bangs and visible flames, followed by the crew regaining climb performance and continuing the emergency response. The A319 later landed safely after the engine problem had left the aircraft with one functioning engine.

The failure occurred during a go-around

The aircraft was already close to the runway when the crew initiated the missed approach. The event therefore combined low altitude, changing thrust requirements and gusty wind with a sudden loss of power from one engine. Contemporary reporting described the failure as catastrophic and noted severe internal engine damage.

The aircraft recovered enough performance to climb away

Despite the engine failure, the A319 climbed away and reached a safer altitude before the crew completed the return. The later landing showed that the remaining engine and the crew's handling were sufficient to complete the flight without a crash.

The public record does not justify a more specific mechanical cause

Contemporary sources identify the event as an engine failure and report severe internal damage, but the publicly available records does not establish a final component-level causal finding. The available record therefore does not convert early descriptions of engine damage into a definitive maintenance conclusion.

The contemporary incident record identifies the event as: “engine failure on go around”
