Short Brothers Model SD3-60 Airplanes Equipped with an Auxiliary Fuel Tank System Installed in Accordance With Supplemental Type Certificate SA00404AT
This AD applies to Short Brothers Model SD3-60 airplanes, certificated in any category, and equipped with an auxiliary fuel tank system installed in accordance with Atlantic Reconnaissance Supplemental Type Certificate (STC) SA00404AT.
We are adopting a new airworthiness directive (AD) for certain Short Brothers Model SD3-60 airplanes. This AD requires deactivation of auxiliary fuel tank systems installed in accordance with Supplemental Type Certificate SA00404AT. This AD results from fuel tank system review requirements done in accordance with Special Federal Aviation Regulation No. 88 (SFAR 88), which identified potential unsafe conditions. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 45 days after the effective date of this AD, submit a report to the Manager, Atlanta Aircraft Certification Office (ACO), FAA. The report must include the information listed in paragraphs (f)(1) and (f)(2) of this AD. Under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements contained in this AD, and assigned OMB Control Number 2120-0056.
(1) The airplane registration and serial number.
(2) The usage frequency in terms of total number of flights per year and total number of flights per year for which the auxiliary fuel tank system is used.
Before December 16, 2008, deactivate the auxiliary fuel tank system, in accordance with a deactivation procedure approved by the Manager of the Atlanta ACO. Any auxiliary fuel tank system component that remains on the airplane must be secured and must have no effect on the continued operational safety and airworthiness of the airplane. Deactivation may not result in the need for additional Instructions for Continued Airworthiness (ICA).
Note 1: Appendix A of this AD provides criteria that must be included in the deactivation procedure. The proposed deactivation procedures should be submitted to the Atlanta ACO as soon as possible to ensure timely review and approval, prior to implementation.
Note 2: For technical information, contact Robert Bosak, Aerospace Engineer, Propulsion and Services Branch, ACE-118A, Atlanta ACO, One Crown Center, 1895 Phoenix Boulevard, Suite 450, Atlanta, Georgia 30349; telephone (770) 703-6094; fax (770) 703-6097.
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.
