The AD requires eventual inspection of all aircraft with more than 22,600 flight cycles. The FAA in the AD preamble estimated that to currently be about 1900 of the NG airplanes.
The part of the pickle fork fitting that is required to be inspected is exposed in the top forward corners of the wheel wells. With all the equipment installed near that location, it is not possible to get your head into positions that allow an adequate direct visual inspection of each of the fittings. Photos of that area that are adequate to detect the cracks have been taken by holding a cell phone up in that area. The AD requires an inspection using a borescope. There is no work required to gain access for the inspection. You just need a ladder and a borescope. It can be done in less than one hour. If you find a crack you are grounded until an approved repair is made.
