"BerettaShotgun - I thought this point had been discussed many times. There is no inherent danger caused by simply adding another hole into the structure of an aircraft. The pressurization of an aircraft is controlled by , usually two, large valves that dump air overboard to set the required cabin pressure. Adding even a 20mm hole is not going to trouble the pressurization one little bit if the damage is simply the extra hole in the aircraft skin. Now, aircraft structure or systems could be damaged. It is possible, but unlikely, that either structure or systems damage would cause an accident. Serious bird strikes and lightning strikes are both events that aircraft are designed to accept."
DUDE!!
I don't think we are talking about a Piper Cub.....
Mr. Rogers:
Ever heard of a reamer?????
Ever drilled a hole in an Aircraft skin????? You ream any lockbolt/hyloc/hi-shear/jo-bolt, and the
drilled hole must be 3 degrees of perpendicular to be acceptable. Must be deburred to be acceptable as deburring relieves any stress crack the drilling operation might have started.
Ever shot a piece of metal and looked at the backside of it???
Ever heard of a catastrophic fatigue failure???
Ever seen the Hawaii Plane, how the fix ended up being a piece of 0.250" doubler ( externally !!
) the length of the fuselage at the lap seam.
Extra holes aren't there normally and from my experience (20+trips around the sun) pilots and engineers typically
frown upon them.
DUH!!!!!!!!!!!
Get real, you (ya'll?) might have thought you had a discussion about a simple hole - but - it AIN'T a CLEAN HOLE. unless he was popping a 38 wadcutter...
I simply don't recall actually having any serious info on this subject to avoid petty speculation.
It is not the same as a bird strike,( which actually makes a dent in the canopy-leading edge or inlet; takes out an engine otherwise if it is a goose or coupla' gulls) and lightning doesn't affect much on alloys (skins).
Lightning, on the other hand, is a holy terror on composites. Mucho repair from lightning strikes on composite panels.
