What to do
Maintenance personnel should carefully verify the orientation of the engine air filter during inspections and replacements, using the 3 mm inspection hole to confirm correct installation. Operators are advised to develop a dedicated work card to guide proper filter installation until a design modification is implemented. There is no mandatory compliance deadline, but heightened attention is recommended immediately.
Summary
EASA Safety Information Bulletin 2010-34 is an informational bulletin concerning CEAPR (Robin) DR400 series aircraft manufactured between 1980 and 1988 equipped with engine air filter part number 56-23-02-000. It addresses an accident involving a DR400/160 where the engine air filter was incorrectly installed, leading to engine performance issues. The bulletin highlights the risk of improper air filter installation causing significant engine RPM loss.
What changed
This bulletin informs operators and maintenance personnel about the potential hazard of installing the engine air filter upside down, which can block the air intake and reduce engine power. It also notes that the filter design has changed, making correct installation harder to verify visually. The Type Certificate Holder is working on a design modification to prevent incorrect installation.
Why it matters
This information is critical for aviation professionals to prevent engine power loss and potential accidents caused by incorrect air filter installation. Maintenance teams must be vigilant during scheduled checks to ensure the filter is installed correctly, especially since the current filter's black rubber bottom is less visible. Proper installation directly impacts flight safety and engine reliability.
