EASA SIB 2023-08R1
Reporting of Occurrences Involving Human Interventions Linked to Flight Deck Design, Operating Procedures, Training, or a Combination Thereof
Summary
EASA Safety Information Bulletin 2023-08R1 is a revision of the previous SIB 2023-08 and addresses the reporting of occurrences involving human interventions related to flight deck design, operating procedures, training, or combinations thereof. It applies specifically to commercial air transport operators of large aeroplanes certified under CS 25, JAR 25, or FAR 25 standards. The bulletin provides guidance on mandatory and recommended reporting of safety-relevant events detected during flight operations and simulator training to the design approval holder to support safety analysis.
What Changed
This revision clarifies previous guidance and expands the recommended minimum content for operator reports to the design approval holder. It emphasizes the need for systematic and comprehensive reporting of human intervention-related occurrences and includes additional examples of events to be reported. The update does not introduce a safety directive but strengthens reporting practices to enhance safety oversight.
Why It Matters
This SIB is important for aviation professionals because it enhances the understanding and reporting of human factors-related safety events, which are critical for identifying potential design or procedural shortcomings. Improved reporting helps design approval holders analyze and address safety risks more effectively, supporting continuous airworthiness and operational safety. Operators benefit from clearer guidance on what to report and how to support investigations.
What To Do
Commercial air transport operators of CS/JAR/FAR 25 large aeroplanes should ensure occurrences involving human interventions detected during flight operations and simulator training are reported to the design approval holder with detailed contextual and technical information. Operators should integrate this reporting into their safety management systems and actively support any follow-up investigations. No specific compliance deadlines are stated, but timely and thorough reporting is recommended.
