Airplanes Originally Manufactured by Lockheed for the Military as P2V Airplanes
This AD applies to all of the airplanes identified in paragraphs (c)(1), (c)(2), (c)(3), (c)(4), (c)(5), (c)(6), and (c)(7) of this AD, certificated in any category:
(1) Aero Union Corporation Model SP-2H (P2V-7) airplanes;
(2) Central Air Service, Inc. Model SP-2H (P2V-7) airplanes;
(3) Evergreen Air Center Model SP-2H (P2V-7) airplanes;
(4) Hawkins and Powers Aviation, Inc. Model HP-P2V-7 airplanes;
(5) Minden Air Corp Model SP-2H (P2V-7) airplanes;
(6) Neptune Aviation Service, Inc. Model SP-2H (P2V-7) airplanes; and
(7) USDA Forest Service (type certificate previously held by U.S. Department of Agriculture) Model P2V-5F (SP-2E) airplanes.
We are adopting a new airworthiness directive (AD) for certain airplanes originally manufactured by Lockheed for the military as P2V airplanes. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires cleaning of the forward lower spar cap between wing stations 40 and 84.5 (right and left), and doing a detailed inspection for cracks, working fasteners, and other anomalies, including surface damage in the form of a nick, gouge, or corrosion; and repairing if necessary. This AD was prompted by a report of a significant crack in the principle wing structure. 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.
Within one day after the effective date of this AD: Do the actions specified in paragraphs (g)(1), (g)(2), and (g)(3) of this AD.
(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.
For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.
Within 10 days after doing the inspection required by paragraph (g) of this AD: Submit a report of the findings (both positive and negative) of the inspections required by paragraph (g) of this AD to the Denver ACO, FAA, Attention: Roger Caldwell, 26805 East 68th Avenue, Denver, CO 80249; phone: 303-342-1086; fax: 303-342-1088; e-mail: roger.caldwell@faa.gov. The report must include a detailed figure or picture of all cracks and damage and the location, orientation, and size of all cracks and damage. The report must also include the airplane serial number, the number of landings and flight hours on the airplane, and a description of how the airplane is operated (e.g., firefighting, photography, etc.).
A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number. The OMB Control Number for this information collection is 2120-0056. Public reporting for this collection of information is estimated to be approximately 5 minutes per response, including the time for reviewing instructions, completing and reviewing the collection of information. All responses to this collection of information are mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at: 800 Independence Ave. SW., Washington, DC 20591, Attn: Information Collection Clearance Officer, AES-200.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
