Doing it was very difficult after the plane was finished and it isn't near as good a job of sealing up the edges. Definitely do it while you have access to the back side.

Cox" When selecting firewall insulation material, it might be assumed that the manufacturer (amateur builder) looked at flame propagation time or just dismissed the guideline published for certificated aircraft in the AC. (Which is often a great "jumping off" point in decision making). Firewall insulation, upholstery covers, carpeting and headliner are often grouped with other "thermal attenuation" and "sound attenuation" products. Some products can do both - they are not always the same. Fire Suppression and flame spread were not listed other than in the description. Often the adhesive used invalidates the purpose for the product in the first place. The ability to remove it and locate corrosion years later should not be dismissed without reasonable consideration. Too often in our quest for completion we totally dismiss "fire annunciation" and "fire suppression" objective of safe building. I had a friend who recently crashed in Virginia, only to extract himself after his canopy burned away adequately. He was in serious condition afterwards. Below is the NTSB report of Boriak's accident. I read in an aerobatics newsletter that he was inverted after the accident and couldn't get out until the canopy melted.

I see variations from the bottom of the green arc to middle of the green arc. There has never been any indication from the engine of lack of fuel. The indications seem to be independent of power. The boost pump will sometimes bring the indication to mid green when it is at the bottom of the green arc on engine driven pump alone. The variations seem to occur randomly. I have an O-320-D1A with about 130 hours on it since new.

What was the altitude when you noticed the low fuel pressure, and how long had it been since you climbed to that altitude? I've seen some reports that suggest that some of the commonly used fuel pressure senders are not very well vented, and it can take some time after you climb for the pressure on the ambient side of its diaphragm to actually decrease to the local ambient pressure. This causes the pressure to read lower than the actual pressure. -- Kevin Horton RV-8 (Finishing Kit) Ottawa, Canada http://www.kilohotel.com/rv8 ________________________________ Message 10 ____________________________________ Time: 06:21:13 PM PST US From: "Kyle Boatright" Subject: Re: RV-List: Thomasville, GA Fly-In Oct. 12, 13, 14 I agree wholeheartedly with Jerry.
