Aluminum Body and Lightening
Aluminum wiring was band many years ago because it can cause house fires when arching. This is what happened when lightening hit an aluminum body Ford pickup. :E Clicky

Many years ago in Belize a pilot and I were returning from tasking in the middle of the country in an RAF Puma helicopter. After landing I got out to do the after flight checks which included checking the rotor blades. There was a small "blister" about the size of a quarter on the underside of one of the blades. There was an identical "blister" on the top side of the blade in the same place. I called over a senior tech and showed it to him. He immediately identified it as a lightning strike. Funny thing was neither the pilot nor myself had any idea it had happened...
Not to hijack the thread, but, out of interest: (I'm a pilot)
What did the tech recommend as a repair?
A. Replace the blade
B. Repair the blade
C. Nothing
D. Other (please specify)
How was the blade fabricated? (material)
Thanks,
