On 9 September 2017, an ATR 72-500 crew temporarily lost control of their aircraft when it stalled whilst climbing in light to moderate icing conditions after violation of applicable guidance. Recovery was then delayed because the correct stall recovery procedure was not followed. A MAYDAY declaration due to a perception of continuing control problems' was followed by a comprehensively unstabilised ILS approach to Madrid. The Investigation concluded that the stall and its sequel were attributable to deficient flight management and inappropriate use of automation. The operator involved was recommended to implement corrective actions to improve the competence of its crews.
