ATA SYSTEM : 27 TITLE : FLIGHT CONTROLS - ELEVATOR SERVOCONTROLS - INSPECTION AND REPLACEMENT OF THE SOLENOID VALVES O-RING SEALS. MODIFICATION No. : None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES Illustrated Parts Catalog (IPC) 27-34-51 Figure 1, applicable to elevator servocontrols Part Number (PN) SC4800-2/-4/-7/-8 calls for installation of o-ring seals PN MS28775-XXX for items 130, 140 and 150, whereas IPC 27-34-51 Figure 1A applicable to elevator servocontrols PN SC 4800-7A/-9, calls for installation of o-ring seals PN NAS1611-XXX. The MS28775-XXX PNs are not qualified for phosphate ester based hydraulic fluid applications and must therefore not be used in elevator servocontrols. Their installation can lead to their complete degradation in a short time. All elevator servocontrols delivered by GOODRICH actuation systems are fitted with the correct seals. But, because the solenoid valves are Line Replaceable Units (LRUs) on the elevator servocontrols, the wrong o-ring seals MS28775-XXX might have been installed when performing the replacement of solenoid valves or seals change, on aircraft or in shop. This Service Bulletin requires within 1,400FH to : — make sure checking in the maintenance and the results recorded in the aircraft data PN NAS1611-XXX or NAS1611-XXXA are installed on active and damping elevator servocontrols (FINs 2CS1, 2CS2, 3CS1, 3CS2), — replace them when there is no evidence that the correct seals are installed. Accomplishment of this Service Bulletin will ensure that correct seals are installed on all A340 aircraft elevator servocontrols.

DESCRIPTION To accomplish this Service Bulletin it is necessary to : (1) Make sure that the correct o-ring seals are installed on the solenoid valves of the elevator servocontrols PN SC4800 FINs 2CS1, 2CS2, 3CS1 and 3CS2 (refer to the maintenance and the results recorded in the aircraft data). (2) In accordance with the results of the inspection, replace the o-ring seals of the solenoid valves of the elevator servocontrols PN SC4800 FINs 2CS1, 2CS2, 3CS1 and 3CS2. E. COMPLIANCE (1) Classification Mandatory (2) Accomplishment Timescale Accomplishment of this Service Bulletin is required within 1,400FH after receipt of this Service Bulletin. European Aviation Safety Agency (EASA) regulatory action is expected for this Service Bulletin by the issue of a Consigne de Navigabilite (CN) (Airworthiness Directive (AD)). It is anticipated that the CN will confirm the thresholds given above but reference should be made to the CN for confirmation of the mandated accomplishment timescale. F. APPROVAL Approved under EASA 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.
