Cessna 188 AGwagon — Airworthiness Directives

This document is an Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) of Australia, specifically concerning the Cessna 188 Agwagon series aeroplanes. The directive outlines the cancellation of a previous AD, AD/CESSNA 188/13, which mandated inspections of the front main spar and doublers at attachment points. The cancellation is based on the fact that the requirements of the revoked AD are now covered by another directive, AD/CESSNA 188/22, which applies to aircraft manufactured prior to 1972, and acknowledges design improvements made in later models. This document serves as an official record of the cancellation and provides historical context regarding the safety inspections of the aircraft's structural components.

• The document cancels AD/CESSNA 188/13 effective 28 August 2008.
• AD/CESSNA 188/13 required inspections of the front main spar and doublers.
• The cancellation is due to the requirements being covered by AD/CESSNA 188/22.
• AD/CESSNA 188/22 applies to aircraft manufactured prior to 1972.
• Later production Cessna 188 models have design improvements for increased wing spar fatigue life.
