Then if you still loss power turn on ISO and see if it increases and stays up. If that is the case, You may need a barametric controller. I have been there done that.

After about a week on the ramp in upstate ny a faa guy looked it over and said the damage had to be repaired before it could be flown. the damaged spot is about the size of a quarter and if you laid a flat edge over it, it would appear to be about 1/16th or a little less. of an inch deep.

I have seen several in the country with similiar chaffing. If talking it through with the inspector does not work then I would call in a DAR cost you a few bucks but usually will cut through the ignorance. Send me a photo when able. N777ZE@COMCAST.NET If you are going to Lancaster TX I will be there and I can see the photos there.

I took a flat edge to it and a caliper and it only measured 32 thousandth at its deepest point. He did not ground me , he saw it sitting on the ramp and put a tag on it saying these things needed to be fixed prior to flight, Well I guess that would be grounding it. Nothing was left out. I can send you a pic of the spot. Any idea how think the metal on the leading edge of that wing is? If I know that maybe I can argue that 32 thousandths will not make any difference in strength. thanks for the info.

Tell him the guy is being un reasonable. Tell him to walk down any row of airplanes and show him all the hail damage. Did he give you any paper work grounding you? Or is this your inspection to obtain your first airworthiness? In any case call and complain. If what you say is fact, and you haven't left anything out, make the call. > > -----Original Message----- > From: mig21driver@charter.net > To: l29-list@matronics.com, l29-list@matronics.com > Subject: Re: L29-List: wing leading edge damage > > --> L29-List message posted by: > > > > call the FAA guy back out....and show him the (other) wing......tell him you fixed it....worked for me! > > From: "Brian Colombo" > > Date: 2005/05/05 Thu PM 09:09:39 CDT > > To: > > Subject: L29-List: wing leading edge damage > > > > --> L29-List message posted by: "Brian Colombo" > > > > ok on my newly acquired l-29 the leading edge of one of the wings was rubbing on the trailer someplace.

If isolation valve did not solve problem suspect fuel flow problem. How many hours are on the airplane?
