Contexto
As a precaution against the loss of important evidence, it is a good practice to mark the position of the blade shank with respect to the propeller hub, but where the drive between the blade and the pitch change mechanism is severed as a result of impact, the significance of these marks will have to be assessed during detailed inspection.
