Beechcraft King Air 350 — Service Manual

This document serves as the Instructions for Continued Airworthiness (ICA) for the Super King Air B300 and B300C series airplanes that have been modified by CenTex Aerospace’s Halo 350 Conversion. The conversion enhances the aircraft's maximum takeoff weight and integrates several safety systems to improve overall safety for both the aircraft and its passengers. This manual is essential for maintenance personnel and operators to ensure compliance with FAA regulations and to maintain the airworthiness of the modified aircraft. It supplements existing Textron Aviation Aircraft Maintenance Manuals (AMM) and provides specific guidelines for the Halo 350 modifications, including maintenance procedures, inspection schedules, and troubleshooting information for newly installed systems.

• The Halo 350 Conversion increases the maximum takeoff weight limit for the Super King Air B300/B300C.
• Main landing gear tire inflation pressures are 97 ± 2 psi when fully loaded and 92 ± 2 psi when unloaded.
• The Ice Mode Stall Warning system adjusts stall warning thresholds in icing conditions, activating automatically when ice is detected.
• Scheduled inspections for Halo 350 equipment must follow the AMM program schedule, including specific tasks for various components.
• The Takeoff Trim Warning system provides an aural warning if the trim is outside the normal range during takeoff.
