Industry and government have worked together to learn more about the effects of aging on aircraft. The focus of their efforts has been on research and regulation that specifically applies to large transports and commercial operations. However, the physics of aging ignore regulatory boundaries. Through this effort, industry has learned much about corrosion, metal fatigue, inspection techniques, and wiring deterioration. Much of this knowledge can benefit GA. 
Methods for mitigating the effects of airplane aging parallel those used in medicine. Advances in medical science continue to result in new methods of detecting precursors to serious health problems. Health professionals recommend increasingly more intrusive “inspections” as people age. People accept these recommendations and generally request more thorough physicals as they get older. Conversely, most small airplanes, regardless of age, are rarely (if ever) inspected beyond a non-intrusive annual or 100-hour inspections as required by 14 CFR 43.15, Appendix D.

Purpose
The recommended best practices contained in this guide are similar to suggested physical exams that doctors recommend. Each airplane ages differently depending on how it is maintained and used over its life. However, airplane design concepts are similar from model to model and from manufacturer to manufacturer. Therefore, these best practices generically apply to all GA models regardless of manufacturer.
