My guess would as well be Thrust Reverser Lock Light...
Nice pics KHAOS!! I was hoping you were going to chime in on this one!
Thanks for posting them!!
I'm not good for much, but at least there are some things. Haha.
I was thinking it was just a lock light as well. This is a fairly common problem from what I've witnessed. This one's probably the 3rd or 4th time it's happened to one of our jets in my 2 years on the ramp. However, it's the first time I've seen the crew perform a shutdown and do a single engine approach.
My dad is an MD-11F Captain for a different airline, and had a similar experience last year. About 200 miles out from KFK, inbound from EDDF, a lock light came on steadily after flickering intermittently across the Atlantic. The #1 engine wasn't shut down, but rather pulled back to idle, and a single engine out approach was performed.
Other than reverser related emergencies I've personally seen, a couple months ago, an A300 performed a no-slats / partial-flaps landing (his brakes were smoking when he pulled in to park btw) after a go-around. Another emergency happened last year when an SA-227 Metroliner III came in after losing an engine on final approach. With that one, I was the marshaller bringing him in, and as soon as he stopped, in quick succession, his engine caught on fire twice momentarily. I almost had to give him the fire signal on that one..
But I digress...awesome job on catching the feed btw.
