| Bob,
Did you log that in the "things to look out for" list?

I mention this because we just found a disintegrated fuel flow impeller (a wee tiny thing to start with) that was blocking the fuel line on a TSIO-550. The owner says the fuel flow was “indicating” even when the engine would barely run, so apparently there was enough impeller in the sensor to at least give a reading, but most of it was down-stream in the fuel system. (the engine did not run well at all…) Bob From: Lancair Mailing List [mailto:lml@lancaironline.net] On Behalf Of Alan Crawford

Subject: [LML] Fuel Pressure Problems Just started having a change in fuel pressure at cruise. I have a Legacy ... 550N ... been cruising 40 to 60 degrees lean of peak with no problem, with fuel pressure above 8.2 psi. Depending on altitude 2500 rpm - 2300 rpm ... 11.5 to 11.8 gph ... The last few flights I can not get 40 degrees lean of peak at any altitude without the fuel pressure dropping below 8.0 psi ... even if I turn on the fuel pump to low = 9, 500 - 11,500 - 12,500 ???? any ideas on what is going on???? Takeoff fuel pressure is 28.0 psi .... Life is NOT a journey to the grave with the intention of arriving safely
in a pretty and well preserved body, BUT rather to skid in broadside,
thoroughly used up, totally worn out, and proclaiming,
"WOW, WHAT A RIDE!!!" |
