PLANNING INFORMATION A. EFFECTIVITY This Service Bulletin is applicable to MYSTERE-FALCON 50 aircraft with serial numbers 2 through 352 which are not equipped with: • LH main landing gear P/N C23791-1009 Amdt F, • RH main landing gear P/N C23792-1009 Amdt F. NOTE: Incorporation of this Service Bulletin makes Service Bulletin F50-510 not applicable. B. REASON On several in-service aircraft, damages have been reported on the main landing gear torque link and the braking system hoses, due to chafing between the external steel braids of the hoses and the torque link. In order to prevent the metallic sleeve from chafing against the metallic guides of the torque link, the installation of a protective wrap on the hoses has been recommended through Service Bulletin F50-510 pending the next landing gear removal for overhaul or repair. As a permanent solution, brake hoses with Dacron sleeves are installed on each main landing gear returned for overhaul or repair. C. DESCRIPTION The operation consists in installing new hydraulic lines, composed of braking hoses fitted with their corresponding stop assemblies and bridges. D. COMPLIANCE If you choose to comply with this Service Bulletin, accomplishment can be performed at your convenience. E.
