He was a mile/mile and a half or so from landing. Why would he attempt a relight? Surely it would have been immediate actions and concentrate on the landing.
If one engine failed, with the different size of the supply tanks giving him another minute or two before number 2 went out, surely he would have spoke to Glasgow (assuming this frequency was still selected)?
Personally, I don't believe he ran out of fuel. The AAIB says MRGB was capable of providing drive to the fenestron drive shaft. I believe that statement may prove to be pertinent. I could very well be wrong, just my personal thoughts.
