I have only had one instance of a surge during my time as a GE.
It happened on the take-off roll from Naples. At about 90kts there was a loud bang, (thump was a better way to describe it), from the right hand side. Initailly, I thought we had blown a tyre but after taxiiing off the runway and looking out the frwd service door it was obvious it was the engine.
The eng then told me there was a rapid rise in TGT with stagnating RPM, he had shut #3 down. I did all the usual post surge checks but oddly enough the was no sign of damage of any sort.
The crew and I tried to start it once more but got the same indications - rise in TGT, stagnating NH. After splitting my head open on the drains pipe
I got a concession to gag the engine. A relief GE flew out to take it home.
As an aside to this, I had to stay in Naples for 3 days until the flight surgeon at the hospital cleared me to go home. Each day I had to take a taxi from the hotel over to the naval hospital. 1 Italian taxi ride is enough to age you decades ! After the third trip I begged the doctor to let me go home before I had a nervous breakdown [-o<
After checking with the bay I found that the ecu had extensive 2nd stage HP Comp damage, uncertain as to the cause.
