(1) No person may operate under this section without a letter of deviation authority (LODA) issued by the Administrator.

(2) The FAA may deny an application for a letter of deviation authority if it determines the deviation would not be in the interest of safety or is unnecessary. The FAA may cancel or amend a letter of deviation authority if it determines that the deviation holder has failed to comply with the conditions and limitations or at any time if the Administrator determines that the deviation is no longer necessary or in the interest of safety.

(3) An applicant must submit a request for deviation authority in a form and manner acceptable to the Administrator at least 60 days before the date of intended operations. A request for deviation authority must contain a complete description of the proposed operation that establishes a level of safety equivalent to that provided under the regulations for the deviation requested, including:

(viii) Notwithstanding any exception due to the experimental airworthiness certification of the aircraft, LODA holders with experimental aircraft must comply with FAA Airworthiness Directives applicable to any corresponding make or model aircraft holding a different type of airworthiness certificate or applicable to any article installed on the aircraft. The LODA holder must evaluate the aircraft and its articles to determine if compliance with the FAA Airworthiness Directive is necessary for the continued safe operation of the aircraft. LODA holders must keep a maintenance record entry of those FAA Airworthiness Directives evaluated. For those FAA Airworthiness Directives for which the LODA holder determined compliance was necessary for the continued safe operation of the aircraft, the record must also include the method of compliance, and if the FAA Airworthiness Directive requires recurring action, the time and date when the next action is required.
