Dornier Model 328-100 and -300 Airplanes
Superseded. A later AD replaced this one: AD 2011-18-13. Comply with the one in force.
This AD applies all Dornier Model 328-100 and -300 airplanes, certificated in any category.
This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2008-10-51 that was sent previously to all known U.S. owners and operators of all Dornier Model 328-100 and -300 airplanes by individual notices. This AD requires detailed visual and eddy current inspections of both the left-hand and right-hand lower wing panel of the rear trailing edge (inboard and outboard of flap lever arm 1 (rib 3 and rib 5)) for cracks, and repair if necessary. This AD is prompted by cracks found in the lower wing panel of the rear trailing edge (inboard and outboard of flap lever arm 1 (rib 5)) during a routine inspection on a Model 328-100 airplane. Subsequent inspection of the other Model 328-100 airplanes in the same fleet revealed several more airplanes with cracks at the same location. We are issuing this AD to prevent structural failure of the affected wing panel, possible separation of the wing from the airplane, and consequent loss of control 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 10 flight cycles, or 10 flight hours, or 7 days, whichever occurs first, after the effective date of this AD: Accomplish a detailed visual inspection of both the left-hand (LH) and right-hand (RH) lower wing panel inboard and outboard of flap lever arm 1 (rib 5) for cracks, in accordance with the Accomplishment Instructions of Dornier Alert Service Bulletin ASB-328J-57-015, or ASB-328-57-037, both Revision 1, both dated May 8, 2008, as applicable. If no crack is detected, repeat the detailed visual inspection thereafter at intervals not to exceed 50 flight hours until the eddy current inspection required by paragraph (g) of this AD is accomplished. If any crack is detected, before further flight, do an eddy current inspection in accordance with paragraph (g) of this AD.
Within 400 flight hours or 3 months after the effective date of this AD, whichever occurs first: Accomplish an eddy current inspection of both the LH and RH lower wing panel in the vicinity of rib 3 and inboard and outboard of flap lever arm 1 (rib 5) for cracks, in accordance with the Accomplishment Instructions of Dornier Alert Service Bulletin ASB-328J-57-015, or ASB-328-57-037, both Revision 1, both dated May 8, 2008, as applicable. Repeat the eddy current inspection thereafter at intervals not to exceed 400 flight hours. Accomplishment of the eddy current inspection terminates the detailed visual inspection required by paragraph (f) of this AD.
If any crack is detected during any inspection required by this AD: Before further flight, repair the crack using a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (or its delegated agent).
(i) Accomplishment of the actions required by paragraph (f) or (g) of this AD before the effective date of this AD in accordance with Dornier Alert Service Bulletin ASB-328J-57-015 or ASB-328-57-037, both dated May 5, 2008, as applicable, is considered acceptable for compliance with the corresponding initial inspection requirements specified in paragraph (f) or (g) of this AD.
At the applicable time specified in paragraph (j)(1) or (j)(2) of this AD: Send 328 Support Services GmbH a report of findings (both positive and negative) found during each inspection required by paragraphs (f) and (g) of this AD. The report must include the inspection results, a description of any cracks found, the airplane serial number, and the number of landings and flight hours on the airplane. Send the report to 328 Support Services GmbH, Global Support Center, P.O. Box 1252, D-82231 Wessling, Federal Republic of Germany; Telephone +49 8153 88111 6666; fax 49 8153 88111 6565; E-mail: gsc.op@328support.de. 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 has assigned OMB Control Number 2120-0056.
(1) For any inspection done after the effective date of this AD: Within 3 days after the inspection.
(2) For any inspection done before the effective date of this AD: Within 3 days after the effective date of this AD.
