Airborne Engine "backfires"?

On Saturday, as our AA 767 was beginning its descent into JFK, I witnessed 3 rapid, succesive flames accompanied by popping sounds coming from the engine right outside my window. The flames seemed quite pronounced.
I was alarmed (scared actually) but seemed to be the only person looking outside at the time. I was sure it was a "flame-out" or foreign object ingestion and that they'd have to shut down the engine.
As my anxiety increased the crew did absolutely nothing. As time passed I realized that it was actually a non-event.

My question is; Is this a common occurence??

Sounds like you witnessed a compressor stall or surge.

Doesn't happen all that often; it's not in the realm of "rare" occurences, but it's not totally uncommon to jet engines.
