Ohio,
CFR 61.51 states that a pilot must allow inspection of his logbook upon request from the FAA.
Question: If a pilot has been served a letter of investigation, is he protected via the "Pilot's Bill Of Rights" from having to provide his logbook to the FAA if the FAA has requested it?
Thanks in advance.
The answer to your question is no, the pilot is not protected from having to provide his logbook.
If you are under investigation by the FAA, you are not required to respond to the letter of investigation and you have no duty to say anything to the FAA. In fact, anything you say to the FAA can be used against you. The NTSB has primary authority, not the FAA.
HOWEVER, there are exceptions to responding to the FAA and one exception is when there are in-flight emergencies, one is with your FAA certificates which must be presented upon request, and another is for logbooks which must be presented for review upon request of the FAA.
From
Frank J. Reno v National Transportation Board; FAA: "Overall safety in air commerce and the public interest require that FAA regulators dealing with record-keeping not be compromised," and from
Administrator v Newman: "... a policy of leniency toward record-keeping [violations] inevitably encourages carelessness ... to the derogation of safety in air transportation."
If you are under investigation, the FAA should have informed you of the charges or the reasons for any actions being taken against you (except in an emergency). You have the right to not only contest the actions but you can also ask to speak with the FAA attorney handling the investigation. You should also seek help from your own attorney, though, before making any statements or taking any actions that could work against you.
There are forum members who are pilots. They will probably respond to your question, as well - and they will correct any misinformation I may have inadvertently provided to you here.
