Bill Crow’s FAA appointment, as a Designated Airworthiness Representative (DAR-T 710516SW), provides authority to accomplish certain work functions that the FAA may not currently have the resources to support.
An active DAR offers and may accomplish certain FAA work functions for its clients that are specifically authorized by, and through the FAA, in a Letter of Authority (LOA) that clearly identifies those DAR authorizations. A DAR’s authority to accomplish certain work functions, on behalf of the FAA, is listed as work function codes in the LOA. Each work function code has a specific detailed explanation of the work function and clearly identifies to the DAR and client alike, what the DAR may accomplish on behalf of the FAA.
Note: When accomplishing work function codes for a client as a DAR, A DAR is representing the FAA in a similar manner as if the DAR was an FAA Inspector and the DAR must follow the same FAA Order 8900.1 work function, policies and procedures and other guidance as a FAA Inspector would be required to do.
The FAA issues a letter of authorization to each DAR listing the functions they can perform. These functions are assigned a code number. Following is a list of these codes and a description of the function:
