I've flown the B767 and B744 into Mumbai many dozen times and the 09 approach was always problematic, in my day the inbound track was on a VOR radial from the BBB and subject to radial instability, hopefully cured by now. Might help if we knew exactly which approach SQ were doing, particularly if it was a training flight.
Do you mean that the crew were being familiarised with the rwy 09 app (with a deliberate deviation to show them Juhu)? But then how would the TC know that rwy 09 would be operational on that day...?
No other a/c deviated from their app track that day so as to point to a probable radial instability from BBB VOR...
Pure speculation from me as well.
