XP Morten, according to the ADC Airlines website, they actually own four 732s.
Here's a link to the previously mentioned 5N-BEE, apparently the only ADC Airlines AC available on Airliners.net.

It looks like flight 66 is the one involved. It could also be the second leg of flight 54. Actually, these 2 flights look the same.
Sorry, it just occurred to me since I'm mentioning flight numbers. My condolences to all who are involved in this terrible tragedy.
