Yingling equipped to provide inspections, solutions for Emergency AD on Cessna 400 Series wing spars

In response to an Emergency Airworthiness Directive resulting from the discovery of cracks in the wing spars of Cessna 400 Series twin engine aircraft, Yingling Aviation is offering operators of affected aircraft full visual and eddy current inspections, as well as modifications designed to correct existing conditions and prevent future propagation.

Yingling, located on Wichita’s Mid-Continent Airport, was the first operation to be named a Cessna authorized service center.

“We have more existing engineering, established maintenance procedures, tooling and expertise working on Cessna twin engine aircraft than any other facility in the world,” noted Lynn Nichols, president of Yingling. “On the basis of our experience providing wing spar proof kits for virtually every 300 and 400 Series Cessna twin, we are the best equipped location in the country for complying with this emergency AD.”

Yingling was instrumental in developing the repair scheme for this AD following the discovery of severe cracking in the vicinity of the forward spar and outboard engine beam on two Cessna Model 402C airplanes. Fatigue analysis also showed that similar fatigue cracks could develop in the wings of the Model 414A airplanes.
