Egt was perfect, actually never passed 600 on start and was at about 450 at idle. I figure it is just because it is so cold out. I did all my run ups and everything was perfect. I took off and climbed out, at about 7000' I noticed my fuel pressure start to drop. No drop in rpm and no change in egt.. I was running about 40-50 at 100% then down to like 30 at 90% and like 22-25 at 80%.When I pull it to idle it drops to about 13-14. I am trying to figure out if this is ok/normal or possibly related to the temp. I figure the low idle is because of the cold temp, but i am far from a 29 expert. The Turbine runs smooth, cool, starts fast and the slam test goes from idle to 100% in 8 sec. Any ideas what is going on. Should I adjust the idle up and if so is it just a stop nut on the throttle arm or is there more to it. Any clue what might be up with the fuel pressure issue and do those numbers seem to be about normal. Thanks in advance.

What does it idle at when you fly it other times? Max fuel pressure is .79. So thats good. I have not seen a minimum fuel pressure listed. As long as the EGT is normal,(less than 700) & Fuel pressure is above "0", throttle response is normal, it should be good to go. Does the fule pressure respond properly when you push up the throttle? Have you checked the Isolation valve operation lately? (1st flight of the day.) Not that it is your problem, but when the high pressure system goes in the toilet, you want to make sure the isolation vavle works!! Have you changed the filter lately? I don't think clogging is the problem, but if you did change it, there maybe a little air in the system?? Guessing now. Bleed the low pressure lines. If there was much air it wouldn't start. In flight, turn off the low pressure pump and see what the pressure does. Have you drained the fuel sump? ----- Original Message ----- From: "Brian Colombo" Sent: Tuesday, March 21, 2006 4:49 PM Subject: L29-List: low idle and fuel pressure issues. > --> L29-List message posted by: "Brian Colombo" > > Ok first off I jumped into my 29 for the first flight since the end of > last fall a few days back, this is the first time I have flown it in cold > weather(25 deg) When I first fired it up I notice it only came up to about > 31% and not the 35-39% it should be at idle.

Yes the fuel will run out. Chances are you will need to bleed the fuel lines after you do that. So the motor may not start due to air. ----- Original Message ----- From: "Brian Colombo" Sent: Tuesday, March 21, 2006 5:36 PM Subject: Re: L29-List: low idle and fuel pressure issues. > --> L29-List message posted by: "Brian Colombo" > > gary, I am doing that tonight.

Idle control valve is going to manage idle, that is adjusted via a knurled knob on the fuel controller. Once you engage the throttle then the HP system is goverened by the Barometric Control Unit. Fuel pressure is measured just beyond the HP fuel pump, so you should never see a change in fuel pressure do to anything that the HP fuel system would do. The decrease in indicated pressure may be due to the effects of cold on the transducer itself or the viscosity of the fuel itself. Bill is right on though, make sure your ISO valve is working and understand the emergency procedures for operating the throttle with the ISO valve engaged. Not bad aye Bill, didnt even look in the manual :) Ernie On 3/21/06, Bill wrote: > --> L29-List message posted by: "Bill" > > Yes, close the fire cock.

Normal idle during the summer months was about 36% I never get near the Max fuel pressure but the min is .12 it is right around there at idle. I checked the isolation switch first flight and i got a slight rise in rpm but not any egt. again it was very cold today and i only switch it on for a few sec(maybe to fast to see a egt change) As i throttle up the fuel pressure goes up, but when I got to about 7000' it was dropping some. always within range 12-79 I have not checked the filter recently but only about 5 hrs on the plane since last annual in aug. EGT was always within limits even a bit low. I will drain the sump tonight and check the filter. I did not do it last time. any tricks to doing it? thanks Brian ----- Original Message ----- From: "Bill" Sent: Tuesday, March 21, 2006 5:41 PM Subject: Re: L29-List: low idle and fuel pressure issues. > --> L29-List message posted by: "Bill" > > What was the idle when you returned to the airport? > > What does it idle at when you fly it other times? > > Max fuel pressure is .79.

At 100% you should be at max 79. maybe not event that high, since that is a max. but certainly up in the 40 to 60 range I would think. Bill's more of an expert than me.

At idle, you won't see much EGT rise with Iso on. Set about 80% and then turn it on and let it stabilize. If RPM goes up, EGT will follow. Move the throttle slow in each direction a small amount to make sure power follows. Draining the sump, stuff paper towels in your arm pits if you don't have the right tool. Drain a half gallon at least. The Czechs drain 6 liters. If you change or inspect the filter, and if you don't have the tool to bleed the fuel lines, let me know. We can tell you how to do it the cheap way. Does your fuel have prist? Just a precaution. The Russians don't use Prist so I wouldn't worry if you don't. Besides, it burns the fuel to fast to ice up! I'm Doubtful that anything is wrong. ________________________________ Message 17 ____________________________________ Time: 04:23:35 PM PST US From: "Brian Colombo" Subject: Re: L29-List: low idle and fuel pressure issues. --> L29-List message posted by: "Brian Colombo" Gary, I do not have a tool to bleed the air.

You can bleed the system using some soft clear tubing, and a panneling nail. Take off the protective cap from the bleed valve which is located at the high point of the BCU. Slip the tubing over (make sure you have about 2 ft so you can route it out of the fuselage and into a can or bottle) then slip the nail through the tubing and down into the bleed va;ve. It works just like a shrader valve. Turn on the LP pump, and puch the nail to depress the bleed valve, fuel should come out, stop when its a clear flow with no bubbles.

I just wanted to make sure I did not have a flame out. I only pulled the throttle back to about 45% during my decent until I entered the pattern then I bumped it up to about 65% I did not pull it back to idle until I was low and slow over the numbers. ----- Original Message ----- From: "Bill" Sent: Tuesday, March 21, 2006 6:25 PM Subject: L29-List: . > --> L29-List message posted by: "Bill" > > What is the RPM at flight idle? > > ________________________________ Message 25 ____________________________________ Time: 06:41:29 PM PST US From: SD737@aol.com Subject: Re: L29-List: .L29 accident --> L29-List message posted by: SD737@aol.com Dallas L-29 runway accident Runway over run?.
