Final report is out on the Darwin Airlines S2000, which got very low during approach to BLL airport. Here's an excerpt of the final conclusions:
3.2 Causes The serious incident emerged from the aircraft’s descent below the stipulated minimum altitude for a non-precision approach. Therefore, a safe altitude above the obstacles was no longer guaranteed. The crew’s poor monitoring of the vertical flight path has been identified as the direct cause of the incident.
The following factors have been identified as directly contributing to the serious incident:
- Deficient approach planning with regards to the vertical flight path.
- Reduced performance of the pilot flying, probably due to tiredness
