The information in this AC is applicable to repairs and alterations of bonded and composite structure, whether it is a damaged part that can be removed from the airplane for repairs, or repairs and alterations on the aircraft itself.

The Federal Aviation Administration (FAA) will consider any other method of compliance that the applicant elects to present. This AC uses mandatory terms such as "must" only in the sense of ensuring the applicability of these particular methods of compliance when using the acceptable means of compliance (AMC) described herein. This AC does not change regulatory requirements and does not authorize changes in, or deviations from, regulatory requirements.
