Based on the information currently available following the accident of flight 4U9525, and pending the outcome of the technical investigation, EASA has made a temporary recommendation to operators to re-assess the safety and security risks associated with flight crew members leaving the flight crew compartment due to operational or physiological needs during non-critical phases of flight.
Based on this assessment, operators are recommended to implement procedures requiring at least two persons authorised in accordance with CAT.GEN.MPA.135 to be in the flight crew compartment at all times, or other equivalent mitigating measures to address risks identified by the operator’s revised assessment.
Any additional risks stemming from the introduction of such procedures or measures should be assessed and mitigated, EASA said.
