Any reason the pilots didn't check the engine chip plug themselves? What operator would let a pilot fly an aircraft without ensuring that first they can at least pull and check a bayonet-type chip plug?
Yeah right!!!!! I remember a day when we were trusted to do such things, but come on Malabo, you know the answer here - I sense you are after a bite! We are not even allowed to look at the cowlings to closely or for too long in case we get funny ideas about opening them!
