The letter of intent should be of sufficient detail to allow the GACA to determine GACA resource requirements necessary to support the GACA RDA process and to assess whether nominated persons (i.e. already appointed GACA-DERs, GACA-DARs, FAA DERs or other foreign delegated individuals/organizations) would have sufficient scope of delegation to address the required compliance aspects of the project.
