The Auditor General's report says that Transport Canada calls for annual inspections:
We also found that although the national planning frequencies state that aviation companies must be inspected every year, about 70 percent of aviation companies across the country were not inspected in 2010–11.
It goes on to say:
Transport Canada has assessed the risk indicators for the five very large air carriers and associated maintenance organizations. For the other 70 large air carriers and maintenance organizations, and about 4,000 small air carriers and maintenance organizations, the Department did not often use the standard risk indicators.
For Canadians who are watching who fly on your airplanes, again, are you not supposed to be inspected annually?
