Thanks Marv, I checked out the site, http://www.lightningtech.com/
and found this under the FAQ on aviation:
> A growing new class of kit-built composite aircraft also raises some
> concerns. Because owner-assembled, kit-built aircraft are considered
> by the FAA to be "experimental", they are not subject to lightning
> protection regulations. Many kit-built planes are made of fiberglass
> or graphite-reinforced composites. At Lightning Technologie's
> laboratory, we routinely test protected fiberglass and composite
> panels with simulated lightning currents. The results of these tests
> show that lightning can damage inadequately protected composites.
> Pilots of unprotected fiberglass or composite aircraft should not
> fly anywhere near a lightning storm or in other types of clouds,
> because non-thunderstorm clouds may contain sufficient electric
> charge to produce lightning. NASA has a Small Business Innovation
> Research project for the development of cost-effective lightning
> protection for kit-built aircraft. Conducted by Stoddard-Hamilton
> Aircraft, Inc. and Lightning Technologies, Inc., the program
> designed and tested lightning protection against severe in-flight
> strikes for Stoddard Hamilton's fiberglass composite Glasair III LP,
> a small high-performance, kit-built aircraft.
I could buy the $99 book, attend the $1575 4-day course on aircraft,
or the $1575 4-day course on avionics. But how many lancair builders
have done that? Perhaps I'll wait for the Osh seminar... ;)
Anyone care to describe specific lightning protection systems or
building techniques used in their own kitplane construction?
thanks,
Rae McLellan
