EASA SIB BEA-2017-02: Embraer EMB-135, EMB-145, ERJ-170 and ERJ-190 Aeroplanes - Software ePerfManager or other not certified software

What to do

Operators and pilots should continue to use the approved Airplane Flight Manual (AFM) for performance calculations and avoid relying solely on ePerfManager or other uncertified software. They should be aware of the identified software issue and apply the manufacturer's recommended updates cautiously, understanding these are not certified. Compliance with RBHA 91 regulations is emphasized, and no mandatory deadlines are specified.

Summary

The Embraer EMB-135, EMB-145, ERJ-170 and ERJ-190 Aeroplanes - Software ePerfManager or other not certified software Special Airworthiness Bulletin provides information regarding the use of ePerfManager software or other non-certified software on Electronic Portable Devices for these Embraer aircraft models. It highlights risks associated with using uncertified software instead of the approved Airplane Flight Manual (AFM). The bulletin is informational and non-mandatory, addressing potential data import issues affecting performance calculations.

What changed

This Special Airworthiness Bulletin identifies a specific issue in ePerfManager software versions 5.2.0 and earlier, where importing airport databases with runway intersections and obstacle distances can result in incorrect runway data and flawed performance calculations. It informs operators that although a fix is available in version 5.2.1, this software remains uncertified. The bulletin does not mandate changes but advises caution and adherence to approved manuals.

Why it matters

This bulletin matters because using uncertified software like ePerfManager for performance calculations can lead to inaccurate data, potentially compromising flight safety and regulatory compliance. Operators and pilots relying on such software risk violating Brazilian aviation regulations that require adherence to approved manuals and safe operating practices. Awareness helps maintain operational integrity and avoid careless or reckless operation violations.
