Systems and methods are provided for inspecting a wing panel. Some methods include advancing a wing panel through a Non-Destructive Inspection (NDI) station, and inspecting the wing panel with inspection heads at the NDI station. The wing panel may be suspended beneath a strongback during inspection and/or advancement, such as by using vacuum couplers and/or adjustable-length pogos of the strongback, and suspending may include enforcing a contour to the wing panel using the vacuum couplers and/or pogos. Other methods include receiving a wing panel at an NDI station and inspecting a portion thereof during movement through the NDI station. Some systems include a track, a strongback to suspend a wing panel beneath it and to advance along the track, and an NDI station disposed at the track to inspect the wing panel while suspended.
