### LANDING GEAR MAIN LANDING GEAR LEGS COMPLIANCE OF CADMIUM PLATING THICKNESS ON PINS

1. PLANNING INFORMATION A. EFFECTIVITY This Service Bulletin is applicable to FALCON 7X aircraft with serial numbers 1 through 89, 92 through 94, 96 through 100, 105, 106, 120, 121 and 124. B. REASON The main landing gear legs fitted on the aircraft listed hereabove, have an insufficient cadmium plating thickness on the following internal pins pintle pins P/N 55-2355007-01. This insufficient thickness increases the risk of corrosion on these pins. The MLG pintle pins are designed to shear in case of excessive load on the main landing gear, ensuring that the landing gear collapses and prevents consequently unacceptable structural damage to the wing. If left untreated, corrosion may reduce the maximal load these pins can bear. The purpose of this Service Bulletin is to replace the affected pins with new ones meeting the cadmium plating thickness requirements. C. DESCRIPTION The operation consists in replacing the main landing gear pintle pin and cross pin with new ones. D. COMPLIANCE Mandatory: • This Service Bulletin is rendered mandatory by EASA Airworthiness Directive No. 2013-0162. • As prescribed by the Airworthiness Authorities of the country of registration of the aircraft. E. APPROVAL The technical content of this document is approved under the authority of DOA nr. EASA.21J.051. F. LABOR Estimated labor-hours: Refer to Service Bulletin Commercial Summary. NOTE: These labor-hours only concern the work described in this Service Bulletin and do not include other maintenance work which may be performed on this occasion. G. MATERIAL - PRICE AND AVAILABILITY The modification kit may be obtained from either address listed below:
