Who bears the cost of psychological and psychiatric tests requested by the FAA?

The pilot is responsible for all costs associated with psychological and psychiatric tests requested by the FAA. This requirement stems from the understanding that the FAA, as a regulatory body, sets the standards for medical certification, but does not directly fund the medical evaluations that pilots must undergo to meet these standards. It is the pilot's obligation to ensure that they comply with FAA requirements, including the financial responsibility for any tests or evaluations mandated by the FAA to assess their fitness to fly. This approach places the onus on the pilot to manage the costs involved in meeting the necessary medical certification standards.
