Including the very recent DHC8 BBQ at Mendi, PX has now lost FIVE (5) hulls in less than a decade
Care to elaborate? 
ASN showing only 2 – PXY at Madang, and PXE at Chuuk. Airfleets.net showing one (PXY), but that’s not been updated to include PXE.Not too sure if the BBQ at Mendi can be attributed to PX either, because the aircraft was on the ground shut down at the time of the event, and from what I heard, the BBQ was beyond the control of PX. So I don’t really think that one counts. I’d really like to know about the other 3 in the last ten years though.
