EASA SIB 2016-09: Minimum Cockpit Occupancy

What to do

Operators should conduct safety and security risk assessments considering psychological screening, crew stability, support programs, and management systems. If two authorized persons are required in the cockpit, operators must clearly define roles, establish safety procedures, provide appropriate training, and document procedures in the Operations Manual. National Authorities should ensure operators incorporate this guidance under their oversight. No specific compliance deadlines are stated.

Summary

EASA Safety Information Bulletin No. 2016-09 is a guidance document addressing minimum cockpit occupancy for commercial air transport operators of large aeroplanes equipped with secure flight crew compartment doors. It provides recommendations on managing the risk of a flight crew member being locked out of the cockpit by another crew member. The bulletin applies to operators under Commission Regulation (EU) No 965/2012 and focuses on ensuring at least one qualified pilot remains at the controls at all times.

What changed

This bulletin replaces EASA SIB 2015-04 and revises its content based on stakeholder feedback. It introduces detailed guidance for operators to perform risk assessments regarding a flight crew member being alone in the cockpit and outlines mitigating measures, including defining the role of an authorized person other than the operating pilot in the flight crew compartment. It also recommends procedures and training to manage safety and security risks associated with cockpit occupancy.

Why it matters

The guidance helps operators mitigate risks related to cockpit security and crew member isolation, which have been highlighted by recent accidents. It ensures that operators maintain safe and secure cockpit environments, reducing the likelihood of deliberate lockouts and enhancing overall flight safety. Compliance with these recommendations supports regulatory oversight and operational best practices.
