Embraer's airplane operations manual was inconsistent with its standard operating procedures manual in relation to speed mode selection. This increased the risk of flight crews departing with the manual speed mode unintentionally selected.
Embraer's E190 airplane operations manual (AOM) has been updated to align with the E190 standard operating procedures manual (SOPM).
Embraer advised that it proposes to align the contents of the airplane operations manual and its standard operating procedures manual in the first half of 2025. This will likely involve removal of the reference to the initial selection of manual mode in the Before start procedure.
Embraer advised that it will harmonise the contents of the airplane operations manual and its standard operating procedures manual in the first half of 2025. The ATSB welcomes this proposed safety action that will likely address the safety issue. The safety issue will continue to be monitored pending completion of the safety action.
Embraer has revised the Embraer E190 airplane operations manual (AOM) to remove 'SPEED knob to MANUAL' action in the BEFORE START procedure. The procedure now reads, 'At pilot's discretion set the SPEED Knob to FMS or MANUAL'. The AOM now aligns with the Embraer E190 standard operating procedures manual (SOPM).
The ATSB welcomes the safety action and acknowledges the changes made to the manufacturer's airplane operation manual (AOM). The ATSB is satisfied that these actions adequately address the safety issue.
