(1) Gain access to the wing spar box between wing stations 40 and 84.5 (right and left sides of the airplane) through an access panel that allows for inspecting the forward lower spar cap assembly and remove or reposition any internal fuel bladder assembly that impedes access. (2) Clean the exposed surface of the forward lower spar cap between wing stations 40 and 84.5 (right and left), and do a detailed inspection for cracks, working fasteners, and other anomalies, including surface damage in the form of a nick, gouge, or corrosion, of the forward lower spar cap between wing stations 40 and 84.5 (right and left). (3) If any crack, working fastener, or other anomaly is found during any inspection required by paragraph (g)(2) of this AD, before further flight, repair in accordance with a method approved by the Manager, Denver Aircraft Certification Office (ACO), FAA. For a repair method to be approved by the Manager, Denver ACO, as required by this paragraph, the Manager's approval letter must specifically refer to this AD.
Unsafe condition
This AD was prompted by a report of a significant crack in the principle wing structure on a Neptune Aviation Service, Inc. Model SP-2H (P2V-7) airplane. We are issuing this AD to detect and correct cracks, working fasteners, and other anomalies in the principle wing structure, which could cause significant loss of structural integrity of the wing.
Affected ADs
None.
