EASA AD BR-E2025-07-03R1
SUPERSEDED BY ANAC BRAZIL AD 2025-10-01
Summary
Brazilian Emergency Airworthiness Directive E2025-07-03R1 is issued by the Agência Nacional de Aviação Civil (ANAC) and applies to Embraer ERJ190-300 and ERJ190-400 aircraft equipped with Engine Feed Check Valve Part Number L85E38-003. This directive mandates inspections and functional tests of the engine feed check valves to address potential valve failures that could lead to engine flameout or fuel starvation during flight.
What Changed
This directive cancels and supersedes EAD No. E2025-07-03/39-1586 dated 29 July 2025. It revises the periodicity of the crossfeed function test for improved timing accuracy and updates the maximum allowable duration for continued testing on aircraft with between 11,900 and 14,000 flight hours.
Why It Matters
The directive addresses a critical safety issue involving accelerated wear and potential failure of the engine feed check valves, which can cause fuel flow obstruction and engine flameout. Compliance is essential for operators and maintenance organizations to ensure flight safety and avoid in-flight engine shutdowns due to fuel system malfunctions.
What To Do
Operators must perform inspections or functional tests of the left-hand and right-hand engine feed check valves according to the aircraft's flight hours as specified, with immediate action required for aircraft exceeding 14,000 flight hours before the next flight. Repetitive inspections are mandated every 10,000 flight hours, and damaged valves must be replaced following the referenced service bulletins. Compliance deadlines vary based on flight hour thresholds as detailed in the directive.
