1. Eligibility

You must be at least 18 years old and capable of entering into a binding agreement. By creating an account, you represent that you meet these requirements.

  • AD data displayed in TachMinder is provided for convenience. Always verify AD applicability and compliance status with the FAA AD database (drs.faa.gov).
  • TachMinder does not certify airworthiness, sign off maintenance, or replace regulatory compliance obligations under 14 CFR Part 91.
  • AI-generated advice is informational and may contain errors. Always consult a qualified aviation professional before making maintenance decisions.
