Beechcraft 99 Airliner — Maintenance Manual

This document serves as the Instructions for Continued Airworthiness (ICA) for the installation of a shoulder harness kit in various Beechcraft models, including the Beechcraft 99. It provides maintenance technicians with essential information to ensure the airworthiness of the installation, following FAA regulations. The document outlines the necessary inspection requirements, maintenance schedules, and troubleshooting procedures specific to the shoulder harness kit installation. It emphasizes the importance of integrating this information into the aircraft's Maintenance Manual and scheduled maintenance program. The ICA is based on FAA STC SA00622WI and includes specific installation instructions and parts information.

• A detailed visual inspection of the sidewall gusset is necessary to detect defects or corrosion.
• The installation does not change the aircraft's dimensions or access to existing systems.
• Cleaning of the harness should be done with a multi-purpose cleaner, and all hardware should be inspected for wear.
