Many inspection activities were deferred into the FY 20/21 as they could not be conducted remotely at the beginning of the pandemic. A change control form was used to document the deferrals, and received 2-key agreement. This is a small percentage of activities and the program will be able to recover in FY 20/21.

At a result of the uncertainties created by the COVID-19 pandemic, there was a need to reduce the frequency of planned baseline compliance verification activities for the 2020-21 fiscal year. Inspections normally done multiple times annually were only done once annually, and inspection normally done multiple times in a 5-year baseline period were reduced as well. These changes were reviewed, reco…

With 2021-22 being the 4th year in the 5-year baseline, a number of activities were not required due to baseline frequency being already met and/or compliance verification was done through other types of compliance verification activities. These changes were reviewed, recorded and assessed from a risk-informed perspective to ensure no impact to safety and oversight.
