What was found
EICAS MESSAGE, RIGHT ENGINE FUEL FILTER DISPLAYED DURING CLIMBOUT. FUEL FILTER DIFFERENTIAL PRESSURE SWITCH WAS REPLACED. THE SWITCH WAS TESTED IN THE SHOP, AND FOUND TO BE SLIGHTLY OUT OF CALIBRATION, BUT NOT ENOUGH TO CAUSE THE EVENT. AS A RESULT OF SHOP FINDINGS, THE MOST LIKELY CAUSE OF THIS EVENT IS A LOOSE CONNECTOR AT THE SWITCH (FIXED DURING SWITCH REPLACEMENT).
