Hearings.

(a) Sections 556 and 557 of title 5, United States Code, do not apply to hearings held under this part. Unless otherwise specified, hearings held under this part are informal, fact-finding proceedings, at which there are no formal pleadings or adverse parties. Any rule issued in a case in which an informal hearing is held is not necessarily based exclusively on the record of the hearing. (b) The NTSB designates a representative to conduct any hearing held under this part. The General Counsel or a designated member of his or her staff may serve as legal officer at the hearing.
