Ki 256 Installation Manual (8K 2026)

Standard avionics hand tools (wire strippers, crimpers, pin extractors). Vacuum/Pressure gauge calibrated for aircraft systems.

Review any relevant service bulletins (e.g., Ki 256 SB11) for modifications, such as replacing the command bar board, to ensure optimal performance. 2. Mechanical Installation The KI 256 fits a standard 3-inch instrument cut-out.

Check Pins E and F for 26VAC. Verify pin continuity to autopilot computer. Missing flight director valid signal from the computer.

Gently slide the KI 256 unit into the sleeve from the front of the panel. ki 256 installation manual

Before cutting metal or running wire, technicians must confirm the variant details of the specific model being installed: Characteristic Specification Parameters Approximately 3.3 lbs (1.50 kg) Pneumatic Supply 4.5 to 5.2 inches of Hg (Vacuum or Pressure) Input Power +14VDC or +28VDC at 0.7 Amps max (Model dependent) Excitation Voltage

The KI 256 is known for needing periodic overhaul due to bearing wear.

Maintaining thorough documentation is crucial. All parts used must be eligible and airworthy. After completing any work, a logbook entry, signed by the installing agent, is required to certify the installation conforms to all applicable regulations.
