Minimum equipment requirements for general aviation under Part 91 — flying legally with inoperative instruments and equipment.
About this document
AC 91-67, Minimum Equipment Requirements for General Aviation Operations Under Part 91, explains how a pilot determines whether an aircraft with inoperative instruments or equipment may still be flown legally. It walks through the 14 CFR 91.213 decision process — the required-equipment lists, the role of a minimum equipment list (MEL) versus the 91.213(d) provisions for aircraft without one, and how to placard and document inoperative items.
