CFO Annual Inspection page



The CFO annual inspection page is a collection of experiences and knowledge gained by Cardinal Flyers around the world and across many years.

Regardless of any suggestions or information that might be exchanged herein, Federal Aviation Regulations, the aircraft operating manual and various publications and communications from the FAA and aircraft and component manufacturers remain the ultimate authority.

There are two display options for this page: Wide format or Single screen/Index format. Both formats contain the same information. Please select the format that works best for your or your system.

The annual inspection information is divided into three sections:

This years watch list: The issues and problems that members have been finding in the last year that deserve special attention at this inspection. Sections:All, FG, RG

Normal Cardinal Specific watch items: Issues and problems that are familiar to most Cardinal owners but still deserve special attention annual.Sections:All, FG, RG

Please help us build this page! We welcome experiences, comments and especially problems found (hopefully with the solution!) Just drop a note to the Webmaster, Keith Peterson
