Bell 412 airworthiness directives
An Airworthiness Directive is a legally enforceable FAA rule (14 CFR 39.3). This page is where you look one up by number, subject or aircraft, see what is still in force, and open the official Federal Register record. How we source and re-check every directive.
What these mean
Active - directives in force today. If your aircraft or engine is listed, compliance is required.
Rescinded - directives the FAA has withdrawn. They stay here so an old logbook entry can still be traced to its record.
Corrections - Federal Register notices that fix an error in an existing directive. Each one attaches to the directive it corrects; none is a new rule.
Active counts directives that have not been superseded or rescinded in our index.
