Another pertinent extract from the report:
The approved Flight Manual for the aircraft states:
“Operation is limited to normal flying manoeuvres and no aerobatic manoeuvres except spins are permitted. [...] The maximum positive acceleration i.e. load factors which the structure has been designed to withstand without permanent deformation are 4.4g for the pull-out from a spin (1400 lb) and for all normal flight (1475 lb) 3.0g and 2.0g with the wing flaps extended (if fitted). Intentional manoeuvres shall be confined to those with load factors below these values.”
