Unsafe Condition
Corrosion and protection deterioration (paint and cadmium coating) of the main landing gear bogie beam could lead to rupture.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect the inner side of the bogie beam between the two axles per specified service bulletins. Repair or replace the beam if cracks or corrosion are found before further flight. Replace beams with corrosion traces in critical areas within 10 months. Perform repetitive inspections at intervals not exceeding 18 months for painted beams or 3 years 6 months if no defects. Incorporate MHB Modification 784 as a terminating action.
AI-generated summary from the source AD text. Verify against the official source before acting.
Compliance Time
For new beams: before reaching 6 years 6 months since new or within 60 days after AD effective date, whichever is later. For overhauled beams: within 6 months after AD effective date or before 3 years 6 months since overhaul, whichever is later. Repairs must be done before further flight.

ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 90-26-03 AIRBUS INDUSTRIE: Amendment 39-6828. Docket No. 90-NM-143-AD. Applicability: Model A300 B4-100 and B4-200, A310-200 and -300, and A300-600 B4- 600 series airplanes, without Messier Hispano Bugatti (MHB) Modification 784, certificated in any category. Compliance: Required as indicated, unless previously accomplished. To detect and prevent corrosion and protection deterioration (paint and cadmium coating) and subsequent rupture of the main landing gear (MLG) bogie beam accomplish the following: A. Perform an inspection of the inner side of the bogie beam between the two axles in accordance with Airbus Industrie Service Bulletins A300-32-394, Revision 3, dated October 10, 1990 (for Model A300 Series Airplanes); A310-32-2053, Revision 1, dated March 5, 1990 (for Model A310 series airplanes); or A300-32-6031, Revision 1, dated March 5, 1990 (for Model A300-600 series airplanes); as follows: 1. For bogie beams which have never been subject to a general overhaul, prior to reaching 6 years and 6 months since new, or within 60 days after the effective date of this AD, whichever occurs later; or 2. For bogie beams which have been subject to a general overhaul, within 6 months after the effective date of this AD or prior to reaching 3 years and 6 months since overhaul, whichever occurs later. NOTE: These service bulletins reference MHB Service Bulletin 470-32-659, Revision 1, dated January 8, 1990, for additional instructions. B. If cracks or corrosion are found, prior to further flight, repair or replace bogie beam in accordance with Airbus Industrie Service Bulletins A300-32-394, Revision 3, dated October 10, 1990 (for Model A300 Series Airplanes); A310-32-2053, Revision 1, dated March 5, 1990 (for Model A310 series airplanes); or A300-32-6031, Revision 1, dated March 5, 1990 (for Model A300-600 series airplanes). NOTE: These service bulletins reference MHB Service Bulletin 470-32-659 for additional instructions. C. For bogie beams with traces of corrosion in a critical area, as defined in MHB Service Bulletin 470-32-659, Revision 1, dated January 8, 1990, replace bogie beam within 10 months following the repair or since the reinstallation on the airplane, whichever occurs later. D. For bogie beams having had paint restoration in a critical area, as defined in MHB Service Bulletin 470-32-659, Revision 1, dated January 8, 1990, perform repetitive inspections at intervals not to exceed 18 months. E. If no corrosion or defects are found, repeat the inspection, required by paragraph A., above, at intervals not to exceed 3 years and 6 months. F. Incorporation of MHB Modification 784, in accordance with MHB Service Bulletin 470-32-672, dated January 23, 1990, constitutes terminating action for the inspections required by paragraph A., D., and E., above. G. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate. NOTE: The request should be submitted directly to the Manager, Standardization Branch, ANM-113, and a copy sent to the cognizant FAA Principal Inspection (PI). The PI will then forward comments or concurrence to the Manager, Standardization Branch. H. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD. All persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to Airbus Industrie, Airbus Support Division, Avenue Didier Daurat, 31700 Blagnac, France. These documents may be examined at the FAA, Northwest Mountain Region, Transport Airplane Directorate, 1601 Lind Avenue S.W., Renton, Washington. This amendment (39-6828, AD 90-26-03) becomes effective on December 27, 1990. FOOTER:
