The training accident during landing was a failure of the left main gear shock strut due to cracking of the high strength steel. The gear was at 15,600 (ish) hrs with a design life of 16,000hrs (ish) and had not been overhauled since the aircraft came onto the EU reg. (nor was there a requirement for there to be)
It is a similar failure mode to those suffered by a variety of aircraft and pariticularly the MD-80 series.
There were no injuries and after changing some bits and a new gear leg the aircraft was flying again within a couple of weeks. I've forgotten the exact details it was a few years ago but a search of the AAIB website should find it.
As for the two crew issue, there was a lot on PPrune about it at the time which i'm not going to drag up, but it has been a total non event these last 5 or is it 6 years now since they were converted. Its an easy aeroplane to operate for 2
