Abstract
A maintenance program is mandatory for commercial aircraft; thus its definition must be part of the aircraft development. This chapter describes the basic parts of the maintenance program and provides examples for interval and duration of scheduled maintenance (checks). Examples of structural damages and principles of the structural repair manual (SRM) are explained, including the definitions of cosmetic, structural, temporary and permanent repair. Important accidental damages are introduced, highlighting the necessity of a robust, impact-resistant yet not too heavy CFRP design. The detectability threshold of CFRP impact damages, crucial to decide on cosmetic or structural repair, is explained. The rationale of bolted repair and a possible repair procedure are described. Advantages and challenges of adhesive bonding repair solutions are discussed, highlighting the specific restrictions of airworthiness authorities.
