Dornier Luftfahrt GmbH Models Dornier 228-100, Dornier 228-101, Dornier 228-200, Dornier 228-201, Dornier 228-202, and Dornier 228-212 Airplanes
This AD applies to Dornier Luftfahrt GmbH Model Dornier 228-100, Dornier 228-101, Dornier 228-200, Dornier 228-201, Dornier 228-202, and Dornier 228-212 airplanes, all serial numbers, that are certificated in any category.
We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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:
Unless already done, do the following actions:
(1) For all airplanes, within 25 hours time-in-service (TIS) after June 26, 2007 (the effective date of AD 2007-11-03), visually inspect the affected fuselage frame 19 using the instructions in Dornier 228 RUAG Alert Service Bulletin No. ASB-228-266, dated December 1, 2006.
(2) If any crack is found during the inspection required in paragraph (f)(1) of this AD, before further flight, contact RUAG Aerospace Services GmbH, Dornier 228 Customer Support, P.O. Box 1253, 82231 Wessling, Germany; telephone: +49-(0)8153-30-2280; fax: +49-(0)8153-30-3030; e-mail: customersupport.dornier228@ruag.com for FAA-approved repair instructions and incorporate the repair on the airplane.
(3) After accomplishment of paragraph (f)(1) or (f)(2) of this AD, as applicable, repetitively thereafter do Structural Significant Item (SSI) Task No. 53.37 of Structure Inspection Program of Dornier 228 Time Limits/Maintenance Checks Manual, Temporary Revision No. 05-27, dated August 4, 2008, at intervals not to exceed 2,400 landings or 72 months, whichever occurs first.
(g) If the number of landings is unknown, calculate the compliance times of landings in this AD by using hours TIS. Multiply the number of hours TIS by 0.8 to come up with the number of landings. For the purpose of this AD:
(1) 800 landings equals 1,000 hours TIS; and
(2) 1,600 landings equals 2,000 hours TIS.
Note: This AD differs from the MCAI and/or service information as follows: (1) The MCAI requires different compliance times for airplanes operated in different conditions. The FAA is not able to enforce compliance times based on airplane operations since there is no way of determining the amount of operations in different conditions. To ensure the unsafe condition is addressed adequately and timely, we are requiring the inspection for all airplanes following a guideline combining number of landings and life limits. (2) The service information allows flight with known cracks provided they do not exceed a certain limit. FAA policy does not allow flight with cracks in primary structure. Since the fuselage is considered primary structure, we are mandating repair before further flight after any crack is found.
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.
