Falcon 7X: 48-Month Telescopic Duct Inspection

February 2012

I was contacted recently by a Senior Aircraft Maintenance Manager for one of the first Falcon 7X aircraft registered in the United States seeking assistance in complying with this Chapter 5 requirement. Being a relatively new model aircraft, this was first time I had received a request of this type. Just like all new model aircraft, the tooling and capabilities aren't always available when the first aircraft comes off the line. Oftentimes, they are developed when operators’ demands dictate it. With help from Todd Hoffman, Phu Ngyun and Mark Lepkey of Duncan Aviation’s Machine Shop and Duncan Aviation Accessory expert Rich Kastl, we have been successful in engineering the necessary tooling and test rigs using the Falcon 7X maintenance manual and a set of new 7X tubes.

If you have any questions about this 7X Chapter 5 requirement, feel free to contact me anytime.
