Aircraft Struck By Lightning?

Thu Apr 27, 2006 9:33 am

Has anybody ever been on airplane struck by lightning? I have, and it was not good feeling. I had a window seat coming in for landing at EWR enjoying the view and then bright flash and then the boom scared the hell out of me never ever want to experience that again.

Ive been on a Delta Md-80 when that happened. No big deal. Ive also been on the ground working flights when one came in after getting struck. Happens not too in frequently actually.

Is it possible that the lightning could do anything to the plane's electrical systems? Also, how is the lightning grounded, does it just go through the exterior of the plane and continue on to the ground, or what?

Yup, just like in cars.

Lightning just goes in and around the metal frame relatively harmlessly. It could affect the comm and nav radios, but properly grounded avionics usually won't suffer any major malfunction, and neither should the rest of the plane.

While working the ramp at an FBO in MKC in the early 90's a resident Jetstar taxied in from a storm with about an 18 inch section of the wing deice boot partly hanging off the leading edge and a nose gear light popped. It was later determined that lightning somehow caused the damage but during the flight the crew and pax were completely unaware of being struck.

Dont ask me how lightning caused the boot to split... I dont know.

All lighting can really do is have the same effect as a bird strike on the fueselage. It can create a rather large hole, but can never really jeopordize the safety of the pax.

You should see what damage it does to trees. A tree in front of our house was split and scorched from top to bottom when struck. The rest of the nearby trees in the yard all died. But I digress.

I was on an SQ B743 many years ago between ZRH and FRA. One of the worst flights I have ever been on turbulence wise. Aircraft got strcuk and we could certainly feel it. The Capt. had to do a PA to explain it was normal, but even he sounded a bit surprised!

Tell that to the 81 passengers of Pan Am flight 214 which crashed on December 8, 1963 near Elkton, Maryland.

"The Board determines the probable cause of this accident was lightning- induced ignition of the fuel/air mixture in the No. 1 reserve fuel tank with resultant explosive disintegration of the left outer wing and loss of control. "

One of my favorite episodes on 'Airline' is when an a/c sets off an APU fire warning, the bring in a replacement and offload the pax, the replacement gets struck by lightening, they haul it off, then the replacement a/c is stuck in MSY. Pax were so mad by the end of the day, but took it in stride.
