The stamp with signature on the filed flight plan says "ARO AIS AASANA" at Viru Viru International. That stamp is placed under the header Additional and not under the header Accepted.
So the immediate questions are:
a. what is the authority of ARO AIS AASANA,
b. could the person placing the stamp withhold the stamp,
c. have there been discussions like ms Celia Monasterio had, and what was the outcome of those,
Question a. should be easy. Point b. requiring a bit more digging. And point c. requiring an indepth investigation.
In an in-depth investigation you would also look at the placement of the stamp. Is it a valid form (it is an FAA form by the way) with that offside placement.
Have to note that it is still very early in the investigation and that this issue is only a small piece in a very large puzzle. The safety investigation will certainly not go beyond factfinding at this stage. But what officials have said till now certainly points to something like a workgroup or sub WG focussing on the 'administrative side'.
