Airbus has updated its operational documentation to clarify engine relight procedures after a LATAM A320 suffered a dual engine flame-out in severe hail during a flight two years ago. The update comes in response to the exceptional circumstances of the incident, where both engines were extinguished due to the intensity of the storm, which exceeded engine design and certification criteria. The water and ice content in the hailstorm was found to be twice the certified level for such conditions.
The incident occurred on October 26, 2022, when the aircraft was en route from Foz do Iguacu in Brazil to Asuncion, Paraguay. The crew had initially diverted to Foz do Iguacu due to adverse weather conditions. After departing from Foz do Iguacu, the flight crew attempted to avoid further weather disruptions by flying northwest, only to turn south towards Asuncion, encountering the hailstorm shortly after.
At the time of the incident, the aircraft was cruising at 24,000 feet with autopilot and autothrust engaged. Shortly after executing a left turn, the plane entered the storm, which resulted in both engines failing due to the extreme hail conditions. Fortunately, the crew managed to safely handle the emergency situation, but the incident highlighted the need for clearer procedures in such rare and extreme weather conditions.
In response, Airbus has worked to refine its engine restart procedures, aiming to provide greater clarity and ensure better preparedness in the event of similar occurrences in the future. This update is part of ongoing efforts by the manufacturer to enhance safety protocols and improve response strategies for pilots when faced with unusual and severe weather phenomena.
