This AD was prompted by cracks found in the lower area of the forward cabin doorpost bulkhead. This AD requires repetitively inspecting the lower area of the forward cabin doorposts at the strut attach fitting for cracks and repairing any cracks. The FAA is issuing this AD to address the unsafe condition on these products.
