1. mandatory and voluntary occurrence reporting, as required by points 21.A.3A and 21.A.139(c) and continued airworthiness as required by point 21.A.165(e);

2. control of work occasionally performed (outside the POA facility by POA personnel);

3. coordination with the applicant for, or holder of, an approved design, as required by points 21.A.133(b) and (c) and 21.A.165(g);
