Hi Ira,

In France, the only two accidents we had with Europas were due to fuel filter blocage. The two aircraft were destroyed and one pilot was killed. The many cases where the engine was restarted after switching to the back up filter are not reported in the statistics. I believe the Europa supplied filters may be acceptable for a 100 HP normally aspirated engine, but the 914, due to the high fuel flow through the filters (around 100 liters per hour) must be regarded as a 500 HP not a 115 HP engine.

Can you point me in the direction of documentation of the "high number"
of accidents or incidents involving fuel filters?

Hi Remi

Thanks for the info about the french accidents.

It seems what's needed is a simple test of pressure drop across
the filter in a 914 aircraft with the flow rate that interested you
for that engine (I only have a 912s).

Of course, one also has to control the contaminants in the fuel as
any filter will clog eventually
