What to do
Operators of EMBRAER ERJ 170-100 and 170-200 models should update the AMS software per EMBRAER Service Bulletin 170-21-0073 and monitor the bleed system as described in Service Newsletter SNL 170-36-0015. Operators of ERJ 190-100 and 190-200 models, excluding the 190-100 ECJ, must follow Service Bulletin 190-21-0068 and monitor per Service Newsletter SNL 190-36-0016. ERJ 190-100 ECJ operators should comply with Service Bulletin 190LIN-21-0033 and the same monitoring newsletter. EMBRAER is advised to continue fleet monitoring to validate certification assumptions. No specific compliance deadlines are stated.
Summary
Special Airworthiness Bulletin BEA 2024-06R1 informs the civil aviation community about a new software update for the Air Management System (AMS) affecting EMBRAER ERJ 170-100, 170-200, 190-100, and 190-200 airplane models. The bulletin addresses a potential dual bleed failure scenario linked to previous AMS software versions prior to Black Label 17.0. It provides guidance to prevent this issue through software updates and monitoring procedures.
What changed
BEA 2024-06R1 introduces a new AMS controller software with Part Number Y1001399-017 to resolve dual bleed system failure events caused by the fan modulating air valve performance reduction. The update requires operators to install the new software and reidentify the AMS controller board following specific EMBRAER Service Bulletins. This bulletin is informative and does not mandate compliance through an Airworthiness Directive.
Why it matters
This bulletin is important for operators and maintenance teams because it highlights a risk of dual bleed system failure that could affect aircraft safety and operational reliability. Implementing the recommended software update and monitoring procedures helps prevent in-flight bleed system shutdowns, ensuring continued airworthiness and minimizing unscheduled maintenance. Compliance with these recommendations supports fleet safety and regulatory expectations without imposing mandatory directives.
