Beechcraft King Air 90 — Airworthiness Directives

This document is an Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) of Australia, specifically for the Beechcraft King Air 90 and 65-90 series aeroplanes. The directive outlines necessary actions to address safety concerns related to the wing front spar. It mandates inspections for cracks and corrosion in the outboard wing main spar, as detailed in the Beechcraft Structural Inspection and Repair Manual. Compliance with the directive is required prior to exceeding five years from the date of manufacture, and subsequently at intervals not exceeding one year. The document serves as a critical safety measure to ensure the airworthiness of the aircraft and is applicable to all models within the specified series.

• All models of Beechcraft 90 and 65-90 series are covered by this AD.
• Inspection for cracks and corrosion in the outboard wing main spar is mandatory.
• Initial inspection must occur before the aircraft reaches five years of age.
• Subsequent inspections must be performed at least once every year.
• The directive references specific chapters and figures in the Beechcraft Structural Inspection and Repair Manual for inspection procedures.
