(d)to examine, remove, test, take measures for the preservation of, or otherwise deal with the aircraft or any part thereof or anything contained therein;
(e)to enter and inspect any place or building the entry or inspection where it appears to the Inspector to be necessary for the purpose of the investigation;
(f)to take measures for the preservation of evidence; and
(g)to order a toxicological examination on flight crew members, if in his opinion, such examination would contribute towards the determination of the cause of the accident.
