### REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES An ALL Operator TeLex (AOT) 57/86/01 has been issued to aLL A300 Operators requesting inspection of the aft hinge brackets of the outer shroud box. This inspection revealed that approximately half of aLL the brackets inspected were cracked. This Inspection Service BuLLetin introduces a visuaL inspection of the forward and aft outer shroud box hinge brackets for cracks or complete fracture of the bracket. AccompLishment of this Service BulLetin wiLL Lead to the early detection of the cracks in the shroud box hinge brackets and wiLL prevent the fracture of the brackets. Fracture of a bracket wouLd allow vertical movement of the inner shroud box structure in the immediate area which could resuLt in damage to the top skin of the inboard flap. Additionally, the Loads carried through the brackets will be transferred to the remaining supports which may also crack and cause extensive structural damage. A detailed visuaL inspection is necessary of the shroud box hinge brackets. The inspection thresholds and repeat inspection intervaLs are given in this Service BuLLetin. In addition, a maximum crack Length is incLuded. This Service BuLLetin has been classified Mandatory by the issue of an Airworthiness Directive (AD) published by the European Aviation Safety Agency (EASA). The AD must be used as the reference document for the mandated accomplishment timescaLe. DATE: Dec 17/86 SERVICE BULLETIN No. : A300-57-0142

This inspection revealed that approximately half of aLL the brackets inspected were cracked or compLeteLy fractured. Fracture of the bracket would aLLow vertical movement of the inner shroud box structure in the immediate area which couLd result in damage to the top skin of the inboard flap. Additionally, the Loads carried through the brackets will be transferred to the remaining supports which may also crack and cause extensive structural damage.

There is also some evidence of 

### un- reported fractures of the forward hinge bracket of the outer shroud box. Modification No. 06661H1033 (Service Bulletin A300-57-0143) has been introduced which repLaces the aLuminum aLLoy aft bracket with a steeL bracket. (2) Objective/Action To do a mandatory detailed visuaL inspection of the LH and RH outer shroud box hinge brackets to detect any cracks or the complete fracture of the brackets. (3) Advantages Accomplishment of this Service BuLLetin wiLL Lead to the early detection of the cracks in the shroud box hinge brackets and wiLL prevent the fracture of the brackets. (4) Operational/Maintenance Consequences

None (5) AccompLishment Timescale This Service BuLLetin has been classified Mandatory by the issue of an Airworthiness Directive (AD) published by the European Aviation Safety Agency (EASA). The AD must be used as the reference document for the mandated accomplishment timescaLe. A detailed visuaL inspection and repeat inspections are to be done on the forward and aft hinge brackets of the outer shroud-box. For aircraft already within the inspection program, the next inspection must be compLeted within the next interval period. However, where the FH Limit only has been exceeded the inspection may be extended to the previousLy planned FC inspection. The inspection thresholds and repeat inspection intervals are detaiLed in TabLe 1.

CAUTIONS LISTED IN THE REFERENCED PROCEDURES. WARNING : MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROL

SURFACES ARE CLEAR BEFORE YOU PRESSURIZE/DEPRESSURIZE A HYDRAULIC SYSTEM. (1) Preparation (a) Make sure that the aircraft is electrically grounded (Refer to AMM: 24-00-00, P. Block 301). (b) To get access to the outer shroud box fwd and aft hinge brackets, extend the flaps (Refer to AMM: 27-51-65, P. Block 401) and the inner airbrakes (Refer to AMM: 27-61-54, P. Block 401). (c) Put warning notices in position in the flight compartment to tell persons not to operate the flight controls. (d) To get access to the inner shroud box, inner attachment brackets, remove and retain the access panels 577CT, 577DT(LH), 677CT and 677DT(RH) (Refer to AMM: 06-21-57, P. Block 1). (e) Get access to the inner shroud-box fwd attachments through the Main Landing Gear Bays (LH and RH). (2) Standard Practices None B. INSPECTION The procedures that follow are applicable to the (LH) and (RH) wings, Refer to Figure 1 . (1) Clean the inspection area with cleaning agent (Mat. No. 11 

### -026) (2) Get access from the top surface of the wing through the gap between the inner and outer shroud boxes. Move the seal between the shroud boxes, as necessary, to visually inspect the top of the outer shroud-box hinge brackets. (3) Do a detailed inspection of the outer shroud-box forward and aft hinge bracket assemblies, as follows: (a) Inspect the small radius between the top flange and the vertical fLange, as shown in example 'A and example 'B' of Figure 1, for signs of cracks on the hinge bracket. (b) Get access from the Lower surface of the wing and with the use of an inspection mirror, visually inspect both halves of the hinge brackets for signs of cracks or fracture of the bracket. NOTE 1 :Each hinge bracket (forward and aft) is manufactured

from two half brackets joined at the vertical face of the fLange which supports its bearing assembly.

### NOTE 2 : The cracks can start in either of the two haLf brackets and run

down the verticaL web radium (example 'A' of Figure 1), or run through the verticaL flange under the bearing assembLy attachment nut (example 'B' of Figure 1). (4) Use the results of the inspection to do one or more of the worksteps that

foLLow: (a) If cracks are not found on either the forward or aft hinge brackets,

do repeat inspections as detailed in TabLe 1 untiL Modification 06661H1033 (Service Bulletin A300-57-0143) is embodied. (b) If a crack is found in one half bracket, do repeat inspections as

detaiLed in Table 1 until a repair is done, as detailed in Para. C. REPAIR. The repeat intervaLs can only be carried out for crack Lengths Less than 8mm. (c) If both half brackets are cracked or a hinge bracket has fractured,

then do a repair as detaiLed in Para. C. REPAIR. 

### Cd) If a crack is found in one half bracket or both half brackets, do a

visual inspection for secondary damage in the areas that follows: 1 The inner shroud-box forward attachments and the attachment

brackets at the inboard end. 2 The inner and out shroud-box structure, adjacent to the

fractured bracket. 3 The top skin of the inboard flap. 

### NOTE : If any damage is found contact AIRBUS for an

applicable repair procedure. (5) If Modification 06661H1033 (Service BuLLetin A300-57-0143) has been

embodied after the fracture of the aft hinge bracket, then visualLy inspect the forward hinge bracket for cracks immediately after the embodiment of the modification.
