摘要

Composite Repairs - Regulation Bonded Structure/Repairs - Summary Bonded Structure - Regulatory/Industry Concerns and Activities: Concerns: CS23.573 allows Bonded Repair sized to Limit Load capability, if the repair is assumed to be failed. AMC 20-29 bounds CS23.573 with further guidance - the failed repair must be readily detectable 'Weak Bonds' and Tight Disbonds' are not always readily detectable Regulatory/Industry Activities: Composite Material Handbook-17 (CMH-17) Delamination/Disbond WG activity (strong Airbus lead) Regulatory/Industry WG - objective to develop clarifying Policy regarding bounds of acceptability for Bonded Repair and/or need for Bolted Repair Increasing industry R&D to improve bonding (Lufthansa Tech, segem etc).
