Hi Rudy Jakma, and welcome.
DaveReidUK is right; "substantially damaged" is the other criterion you may have forgotten.
The BEA released a statement on 27 October, as many of you will have noted:
Fokker 27, Paris Charles de Gaulle Airport, France, 25 Octobre 2013
Today's version in French adds a photo of the propeller hub:
Fokker 27, 25 octobre 2013, aérodrome de Roissy Charles de Gaulle (93)
The caption:
Vis de fixation en place dans la pale,
présentant des caractéristiques de rupture en fatigue (lignes d'arrêt).
Des examens plus approfondis vont être entrepris sur la pale d'hélice.
Roughly translated:
Fixation screw in place in the blade, presenting characteristics of fatigue-rupture.
A more thorough examination is going to be carried out on the propeller blade.
Does that mean they have found the missing blade, I wonder?
I infer that the BEA regards the blade mounting screw (to the hub) as the primary failure.
