The face veneers and inner plies for aircraft plywood are free of open defects. However, tiny sound tight knots are allowed in the face plies. Gaps and voids are not allowed in core layers . Usually the back veneers are a little worse than the face veneers because a few tiny defects are allowed in the back veneers . But the back veneers can be the same good grade as face veneers .
