This order specifies procedures for Control Tower Operator (CTO) certificates governed by Title 14 of the Code of Federal Regulations (14 CFR) part 65 and Air Traffic Safety Oversight Credentials (Credentials) authorized by Federal Aviation Administration (FAA) Order 1100.161, Air Traffic Safety Oversight. In addition, consistent with the regulations, this order eliminates the requirement for an air traffic control tower operator to hold a CTO certificate if the individual holds a Credential with a tower rating. The requirement to hold both the CTO certificate and the Credential is unnecessary since the underlying requirements for the Credential encompass those of the CTO certificate. CTO certificates will only be issued to those individuals who do not hold a Credential and who meet the requirements of 14 CFR part 65, subpart B.
