The Calco Mfg 8219‑M2 is a 28 V, 1 A electromechanical actuator used in aircraft trim or cowl flap systems. Common failure modes for this class include coil winding degradation, bearing wear, and electrical contact corrosion; the unit may also suffer from mechanical binding due to rust or pitting. First‑check steps: verify 28 V supply continuity and current draw against spec, inspect the actuator shaft and bearings for looseness or debris, and examine the coil terminals for signs of burn or corrosion before proceeding with a detailed electrical test.[oss-gpt-20b] |
