(d) If a test is cancelled for a correctible flaw (e.g., § 40.203 or § 40.205), only the MRO who cancelled the test can reverse the cancellation and must do so within 60 days of the cancellation. After 60 days, the MRO who cancelled the test cannot reverse the cancellation without the permission of ODAPC. For example, if an MRO cancels a test because the MRO did not receive a copy of the CCF, but later receives a copy of the CCF, the MRO may reverse the decision to cancel the test within 60 days. After 60 days, the MRO must contact ODAPC for permission to reverse the cancellation. An MRO must not reverse the cancellation of a test that the laboratory has reported as rejected for testing, as described in § 40.83(g). A laboratory is not authorized to reverse a cancellation due to a fatal flaw, as described in § 40.199.
