The forward hole is 18 mm from the forward edge of the fitting. Issues: (1) The firewall flange is 18 mm wide, and even considering that the thickness of the doubler will position the bolt hole a little farther away from the firewall web, the hole will still touch the firewall flange. And (2) drawing 6F9 shows the forward bolt going through the lower firewall doubler (and presumably through the firewall flange). I haven't found pictures that clearly show where this bolt was installed by others. Any comments? Thanks in advance Carlos CH601-HD, plans ________________________________ Message 2 _____________________________________ Time: 11:39:51 AM PST US Subject: Re: Zenith-List: firewall engine fittings (CH601-HD ) From: Jay Bannister Carlos, This is a photo of my 601XL under construction. I don't think it would be that much different from your HD. It clearly shows the forward bolt hole ( with cleco) going through the firewall flange. As I recall, because of the proximity of the bolt heads, the engine mount bolt had to be inserted and tacked into place before the forward bracket bolt was installed.
