Belgian aviation expert Luc De Wilde: "The plane was involved in an accident at Moorsele aerodrome in West Flanders in 2000. It crashed shortly after take-off. Several people were injured. The plane was not a total loss. It was repaired and passed an inspection."
"It regularly happens: aircraft crash and are later repaired. All depends on the parts that were damaged. They examine whether repairs can be carried out and if safety can be guaranteed. The authorities then check whether the repairs comply with the guidelines."
There have been safety concerns about this type of plane for a while.
Luc De Wilde: "Three years ago the European Aviation Safety Agency, the EASA, issued a warning for this type of plane, the Pilatus Porter, built in the 60's. The craft may show signs of corrosion and need to be thoroughly checked every year."
