The CH-7 Heli-Sport has a poor safety record in Australia, with two crashes caused by structural failure of the stabiliser.
As the number of CH-7's in Australia is low, this is an exceptionally high percentage of failures and resultant crashes.
The ATSB crash reports for VH-SWQ and VH-JEW are at the bottom of the page. Both crashes were fatal, and in both cases, the CH-7 was destroyed.
