What to do
Design Approval Holders of type certificates with flight recording systems installed before the latest amendments should review and update their equipment Instructions for Continued Airworthiness to provide sufficient maintenance guidance and data conversion information. Aircraft operators should incorporate these requirements into their maintenance programs, regularly inspect recording quality, and report any malfunctions or deficiencies to the competent authorities and type certificate holders. No explicit compliance deadline is stated, but timely action is recommended to ensure ongoing serviceability and regulatory compliance.
Summary
EASA Safety Information Bulletin 2009-28R2 is an airworthiness bulletin addressing the serviceability of required flight recording systems installed on aircraft certified under CS-25, CS-29, CS-27, and CS-23 standards. It targets Supplemental Type Certificate holders, maintenance organizations, and operators to ensure flight data recorders, cockpit voice recorders, and lightweight flight recording systems maintain proper functionality and data quality. The bulletin also informs National Aviation Authorities and Safety Investigation Authorities about issues related to dormant failures and data conversion challenges.
What changed
This revision updates the previous SIB 2009-28R1 by incorporating regulatory changes related to data link recording and Instructions for Continued Airworthiness (ICA) for flight recorders introduced in CS-25 Amendment 26, CS-29 Amendment 9, and CS-27 Amendment 10. It expands recommendations to include lightweight flight recording systems and clarifies maintenance and operational check requirements to align with ICAO Annex 6 and EUROCAE standards. The bulletin also emphasizes the inclusion of flight recorder decoding documentation in the ICA to aid operators in data conversion.
Why it matters
This bulletin highlights the critical importance of maintaining the serviceability and data quality of flight recording systems to support effective safety investigations and regulatory compliance. Operators and maintenance organizations must ensure that flight recorders do not suffer from dormant failures and that recorded data meets required standards for intelligibility and accuracy. Proper documentation and maintenance instructions from type certificate holders are essential to enable timely and accurate analysis of flight data, which directly impacts flight safety and regulatory adherence.
