Some Design Considerations

Aircraft design standards provide the requirements and/or guidance to assist a manufacturer in providing a safe and durable airframe for a specific period of operation or an inspection-free period. The standards also advise on the design and in-service tasks or general aspects/elements that are required to achieve and maintain structural airworthiness. However, in some instances operational objectives mean that the original certification basis may be inadequate and further remedial action is required to maintain airworthiness as discussed.
