2020-24-10: Flight Controls

The Amendment \n\n\n\tAccordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n0 1. The authority citation for part 39 continues to read as follows: \n\n\n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n\n\nSec. 39.13 (Amended) \n\n0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive: \n\n2020-24-10 Aerostar Aircraft Corporation: Amendment 39-21340; Docket No. FAA-2020-0574; Product Identifier 2019-CE-015-AD. \n\n(a) Effective Date \n\n\n\tThis airworthiness directive (AD) is effective January 22, 2021. \n\n(b) Affected ADs \n\n\n\tNone. \n\n((Page 82310)) \n\n(c) Applicability \n\n\n\tThis AD applies to Aerostar Aircraft Corporation Model PA-60- 601P (Aerostar 601P), PA-60-602P (Aerostar 602P), and PA-60-700P (Aerostar 700P) airplanes, all serial numbers, certificated in any category. \n\n(d) Subject \n\n\n\tAir Transport Association (ATA) of America Code 27;Flight Controls. \n\n(e) Unsafe Condition \n\n\n\tThis AD was prompted by reports of corrosion on the elevator and aileron balance tubes. The FAA is issuing this AD to detect corrosion on the elevator and aileron balance tubes. The unsafe condition, if not addressed, could result in failure of the aileron and elevator balance tubes, jamming of the aileron and/or elevator balance tubes, and loss of control of the airplane. \n\n(f) Compliance \n\n\n\tComply with this AD within the compliance times specified, unless already done. \n\n(g) Repetitive Inspections \n\n\n\tWithin 10 hours time-in-service after the effective date of this AD, inspect the elevator and aileron balance tubes for corrosion (pitting and flaking) and rust (discoloration) by following steps 1. through 3. of Part I (Inspection) of the Instructions in Aerostar Aircraft Corporation Service Bulletin SB600-138, dated August 30, 2018 (Aerostar SB600-138). For each tube replaced as required by paragraph (h) of this AD, using a borescope, repeat the inspection within 10 years after replacing the tube and thereafter as follows: \n\t(1) At intervals not to exceed 10 years as long as no rust is found. \n\t(2) At intervals not to exceed 2 years if only rust is found (without any signs of corrosion). \n\n(h) Replacements \n\n\n\tAt the following compliance times, replace each elevator and aileron balance tube by following Part II (Replacement) of the Instructions in Aerostar SB600-138, except you are not required to report information to the manufacturer: \n\t(1) Before further flight if corrosion or rust is found (inside or outside the tubes) during the initial inspection required by paragraph (g) of this AD. \n\t(2) At the next 100-hour inspection or at the next annual inspection, whichever occurs first, if no corrosion and no rust is found (inside or outside the tubes) during the initial inspection required by paragraph (g) of this AD. \n\t(3) Before further flight if corrosion is found (inside or outside the tubes) during any repetitive inspection required by paragraph (g) of this AD. \n\n(i) Alternative Methods of Compliance (AMOCs) \n\n\n\t(1) The Manager, Seattle ACO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate.
