Narrative:

Aircraft overtook us while departing ads. Instead of overtaking on the right; which is the correct procedure; the aircraft passed underneath us; and appeared to still be climbing up towards us. I heard the tis warning; looked below; and saw the aircraft. Taking action was not necessary; as the other aircraft was much faster than us; and by the time I saw him; he was going to clear us by a few hundred feet. A collision was not imminent. However; separation was not adequate. This near-miss could have been avoided by 1) the other pilot using the correct procedure to overtake an aircraft. Also; the other aircraft was low wing; so visual scanning would not have been impaired; and it's possible that they were not looking above them for traffic. 2) we could have prevented this by looking below us for traffic; as opposed to looking out ahead; and side to side.
