DRUK,there is no date known ,or given about the first mid-air ; only that after repair he test flew the aircraft on 15 Feb,and that the friend flew it on the 16 Feb with fatal results. A 10 ft splice job would take certainly a week or more as if it was repaired on site,Anglesey in winter is not an ideal place for glueing wings back together,re-covering,painting etc...would have been quicker to have changed the whole wing...maybe they went to the `graveyard and did a bit of cutting on a `hangar queen`.....
