stopped, we'd be done. however, he did a subsequent inspection, he went back and looked again and they were not following the procedures, loosely followed, some in the refrigerator and some were not, back in the place they were before. his concern is that these pingers, which are replaced every 1,000 hours were indeed put onto this particular aircraft. >> do we have any way of tracking that? are they that careful with what was stored where? and i'm only guessing that malaysia airlines has everybody on working back ward to find out if they've got a warm storage pinger or a cold storage pinger on flight 370. >> yeah. now, remember after he did this audit they came back and revised the procedures. so the procedure would be to say i put this particular serial number in refrigerator, i took it out and put it on this serial number aircraft. but as he said they are loosely following the actual place that they put them. i'm confident they're doing the rest of the procedure right because they have what we call the rii, the required double inspection. so at that point they're going to make sure it was done right.
