BEFORE NEXT FLIGHT!  If your IV or any other Lancair model has a hydraulic 
system filter (p/n B-4F-60) installed, before your next flight disassemble 
the filter (use 3/4" wrenches) and discard the sintered metal filter element 
and the spring.

HI , is this the one that is very close to the return side of the emergency 
handpump?

Martin, the parts in (both sides) of the emergency hand pump lines should be 
check valves. It's important that they not be removed. The filter in question 
is an "aftermarket" item sold in the Lancair Catalogue, and not included in 
any kits as original equipment as far as I can tell. It looks a bit like one 
of the kit-provided check valves, but is a bit bigger in diameter. Although 
this filter could be installed anywhere in the system, most knowledgeable 
builders would install it somewhere in the main hydraulic pump return line. 
Send me a direct post and I'll send you a digital picture if you'd like.
