GM 21.A.605(b) Reporting from the compliance demonstration process and updates to the certification programme    

CAA ORS9 Decision No. 1

The applicant should report to the CAA any unexpected difficulty or event encountered during the compliance demonstration which invalidates or appreciably affects the assumptions previously made, e.g.:

1. an increase in the severity of the consequences of a certain condition (e.g. a failure mode) of the article;

2. one or more significantly reduced margins on the ‘pass–fail’ criteria of the compliance demonstration;

3. an unusual interpretation of the results of the compliance demonstration;

4. a deviation from the agreed means as defined in the certification programme;

5. a change to the conditions set out in the AMC No 2 to 21.B.100(b); and

6. any potential deviations discovered by the applicant.

The applicant should also evaluate whether the unexpected difficulty or event encountered will impact on the certification programme and, if necessary, they should amend the certification programme as per point 21.A.603.
