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). For A330-200 aircraft operators, only make sure checking in the maintenance and the results recorded in the aircraft data PN NAS1611-XXX or NAS1611-XXXA are installed on active elevator servocontrols (FINs 2CS1, 2CS2). The elevator servocontrols installed in damping position (FINs 3CS1 and 3CS2) are already addressed by AOT 27A3129 Rev. 1 dated 16 July 2004 and further revisions). — replace them when there is no evidence that the correct seals are installed.
