The SOP for landing requests that the flight crew perform a full stop landing after thrust reversers selection. However, in-service flight data analysis revealed that the equivalent of one go-around per month is performed after selection of thrust reversers.
This article describes an event where the flight crew performed a go-around after they had selected thrust reversers on an A320 aircraft. The reverser on one engine remained deployed until the end of the flight.
The article explains how adherence to SOPs will prevent recurrence of this kind of event and describes the product enhancements that Airbus developed as additional safety barriers.
