Re: Fuel tank grounding

[Peter S. Lert <peterlert@montrose.net>]

A lot of European aircraft (including some jets, etc.) have a little
piece of aircraft cable bonded on to one of the landing gear forks such
that it brushes the ground.  Obviously, this is a "sacrificial" bit that
needs to be replaced now and then, although swaging a piece of very hard
material (e.g. a piece of Stellite arc welding rod) onto the end will
increase the service life.
