### TITLE: HYDRAULIC POWER - IMPROVE EATON EMP ELECTRICAL ROUTING AND HYDRAULIC PIPES STRENGTH **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR 13667S22874 MINOR None NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the mass, balance, structural strength, reliability, operational characteristics affecting the airworthiness of the product. All other changes are major changes. REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES An operator reported an electrical arc and a large hydraulic haze in the Left Hand Main Landing Gear (LH MLG) wheel bay that occurred during ground operation. The analysis revealed that this occurrence was likely caused by chafing between a hydraulic high pressure hose and electrical wiring of the Green Electrical Motor Pump (EMP). This condition, if not detected and corrected, and in combination with a system failure leading to the use of the Green EMP in flight, could lead to an uncontrolled and undetected fire in the LH MLG wheel bay. This Service Bulletin consists in improving the routing of Green EATON (formerly VICKERS) EMP power supply (FIN 11GE and 12GE) and in improving the hydraulic hose routing to Green EMP (FIN 11GE). Accomplishment of this Service Bulletin will prevent chafing between the electrical conduits and hydraulic pipe and hose.

E. COMPLIANCE (1) Classification MANDATORY: Service Bulletin must be accomplished. (2) Accomplishment Timescale This Service Bulletin must be accomplished before 36 months from the effective date of the EASA AD. This Service Bulletin has been classified Mandatory. It is expected that an Airworthiness Directive (AD) published by the European Aviation Safety Agency (EASA) will be issued to confirm this classification. The accomplishment timescale, which has not yet been defined, will be given in the AD. F. APPROVAL The technical content of this document is approved under the authority of Design Organisation Approval No. EASA.21J.031. If an aircraft listed in the effectivity has a modification or repair embodied that is not of AIRBUS origin, and which affects the content of this Service Bulletin, the operator is responsible for obtaining approval by its airworthiness authority for any adaptation necessary before incorporation of the Service Bulletin. G. MANPOWER The manpower estimates given in this Service Bulletin are based on the direct labor cost to do the work. These estimates assume that the work will be done by experienced personnel, and may need to be revised upwards to suit operator’s circumstances. The estimates do not include the time to prepare, plan or inspect the work. Manufacture and procurement of parts and tools, drying times for paints, sealants, etc., and general administration work are also not included.
