Ummm…. lightning strike?
AvWeb has the same picture, and reports that the probably cause was “an electrical fire while the aircraft was being preflighted in Tallahassee for a trip to Atlanta last March 1.” See http://www.avweb.com/avwebflash/news/ASACRJHoled_200121-1.html .
The AvWeb article references NTSB report DCA09FA033 , which is also worth a read: http://www.ntsb.gov/ntsb/brief.asp?ev_id=20090303X74824&key=1 .
Blue skies!

Well…. Here is an account of a “non trivial” lightning strike on a small composite aircraft, ( a glider ) an ask-21. It makes me wonder how the new generation plastic airliners will do.
This fellow was having a series of “40th birthday” rides:

Whoops, thanks for the correction guys, I didn’t follow up on the story but took what was offered at face. Lesson there I think.
Looking at it closely it was an initial surprise that the event was a lightning strike, as I said the damage is (modern aircraft) normally less dramatic than the one shown.
As for composite structures, bonding against lightning strikes and the like. I Understand that Boeing’s headaches with the 787 may be related to this kind of problem as well as that of fasteners. I have not researched the current state of play (787) recently but that is the scuttle-butt.
Thanks for reading folks – I am still rattling away at a set of manuals at the moment hence the lack of activity here. I need to spend a bit more time on TDA.
Kind regards to all,
Norman
