Thanks guys. I have forwarded to the Lancair Mail List since this is certainly of general interest to all. There has been an active dialog on lightning, among other subjects. If you have any questions about Lancairs or their operations, you can get a bunch of informed answers here. All Lancairs are composite, with varying amounts of carbon fiber and fiberglass.
Please send pointers to any reports as they become available -- Good luck with the research!!

The panel shown in the video was indeed carbon fiber composite, but did not have the typical copper mesh lightning strike protection present on today’s airliners. I’m not sure specifically about the parameters of the test and composition of the panel, but am cc’ing George & Ken in case they have some more information that is ready to share.

Subject: Re: Backup gyros and lightning strike Walt, thanks for that interesting footage. Do you happen to know if that was a carbon skin? Since carbon has "some" conductivity I'm wondering if it fares a little better. On Jul 26, 2013, at 8:21 AM, Engelund, Walter C.

Perhaps I should've waited until we had the problem solved before offering a visual of what happens to composite skin in a lightning struck event… |
