An 2 Checklist

This document provides a checklist for preflight inspection, engine start up, warm up, engine testing, and checks before taxi for an ANTONOV AN-2 aircraft. The checklist includes over 50 individual inspection and testing items to verify the aircraft and engine are safe and functioning properly before flight. It details checks of the cockpit, engine, landing gear, wings, tail, passenger cabin, and engine start up and warm up procedures. The goal is to ensure all critical aircraft systems are operating normally and within limits before taking off.
