This AD applies to 328 Support Services GmbH Dornier Model 328-100 airplanes on which a rudder spring tab lever assembly having part number 001A272A4020-002 is installed, and all Model 328-300 airplanes.
We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Required as indicated, unless accomplished previously.
For all airplanes: Within 400 flight hours or 2 months after June 9, 2004 (the effective date of AD 2004-09-16), whichever is first; do detailed and eddy current inspections for cracking of the bearing lugs of the rudder spring tab lever assembly by doing all the actions per Paragraphs 2.A., 2.B., and 2.D. of the Accomplishment Instructions of Dornier Alert Service Bulletin ASB-328-27-036 (for Model 328-100 airplanes), dated February 12, 2003, or Revision 3, dated February 8, 2008; or Dornier Alert Service Bulletin ASB-328J-27-013 (for Model 328-300 airplanes), dated February 12, 2003; as applicable.
Note 1: For the purposes of this AD, a detailed inspection is defined as: “An intensive visual examination of a specific structural area, system, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at intensity deemed appropriate by the inspector. Inspection aids such as mirror, magnifying lenses, etc., may be used. Surface cleaning and elaborate access procedures may be required.”
(1) For Model 328-100 airplanes: If no cracking is found during any inspection required by paragraph (g) of this AD, do the next inspection within 400 flight hours after doing the last inspection, or within 400 flight hours after the effective date of this AD, whichever occurs later; and repeat the inspection thereafter at intervals not to exceed 400 flight hours. Repeat the inspections until the replacement required by paragraph (k) of this AD has been done.
(2) For Model 328-300 airplanes: If no cracking is found during any inspection required by paragraph (g) of this AD, repeat the inspections thereafter at intervals not to exceed 24 months.
For all airplanes: If any cracking is found during any inspection required by paragraph (g) of this AD, do the applicable actions specified in paragraph (h)(1) or (h)(2) of this AD.
(1) For Model 328-100 airplanes: Before further flight, do the replacement required by paragraph (k) of this AD, or replace the spring tab lever assembly with a new assembly by doing all the actions per Paragraph 2.C. of the Accomplishment Instructions of Dornier Alert Service Bulletin ASB-328-27-036, dated February 12, 2003; or Revision 3, dated February 8, 2008.
(2) For Model 328-300 airplanes: Before further flight, replace the spring tab lever assembly with a new assembly by doing all the actions per Paragraph 2.C. of the Accomplishment Instructions of Dornier Alert Service Bulletin ASB-328J-27-013, dated February 12, 2003. Repeat the inspections required by paragraph (g) of this AD thereafter at intervals not to exceed 24 months.
Note 2: For Model 328-300 airplanes: There is no terminating action available for the repetitive inspections required by this AD.
(i) Dornier Alert Service Bulletins ASB-328-27-036, dated February 12, 2003, and Revision 3, dated February 8, 2008; and ASB-328J-27-013, dated February 12, 2003; recommend reporting crack findings and returning damaged lever assemblies to the manufacturer, but this AD does not contain such requirements.
For Model 328-100 airplanes: As of the effective date of this AD, Dornier Alert Service Bulletin ASB-328-27-036, Revision 3, dated February 8, 2008, must be used for accomplishing the inspections and corrective actions required by paragraphs (g) and (h) of this AD.
(k) For Model 328-100 airplanes: Within 6 months after the effective date of this AD, replace any rudder spring tab lever assembly having P/N 001A272A4020-002 with an improved unit having P/N 001A272A4020-004, in accordance with the Accomplishment Instructions of Dornier Service Bulletin SB-328-27-459, Revision 2, dated February 8, 2008. Accomplishment of the replacement required by this paragraph terminates the repetitive inspections required by paragraph (g)(1) of this AD.
