A crack growing in the forward wing trunnion of a CF100 aircraft was monitored for over 60 flying hours. Acoustic emission data was detected which indicated that during climb, following take-off,the 3mm crack made unstable advances on a few occasions. The detected crack advances produced about 1mm2 of new fracture surface.
