Yingling offers solutions for emergency AD on Cessna 400 wing spars

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

Yingling, located on Mid-Continent Airport in Wichita and the first operation to be named a Cessna authorized service center, developed the repair scheme for the AD following the discovery of 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. The FAA issued the AD March 2 requiring visual inspections for all Model 402C airplanes with fewer than 15,000 to time in service (TIS) and repetitive inspections at intervals not to exceed 110 hours TIS until accumulating 15,000 hours. The FAA requires initial inspections within the next two days following receipt of the emergency AD for specified aircraft and outlines procedures for conducting both the inspection and the repair process in the event that cracks are found.
