Do the operations that follow: (a) (b) (c) (d) (e) (f) (g) (h) (i) (j) Remove the Mask Regulator from the stowage box as defined in the relevant Operating and Maintenance Instructions. ZODIAC AEROTECHNICS recommends that a complete functional test be performed at minimum of once a year as described in the Aircraft Maintenance Manual or Maintenance Instructions as supplemented by 4NUT0045A (MC10 Series), 4NUT0046A (MF10 Series), 4NUT0047A (MC10/MF10 Series), 4NUT0089A (MC20 Series), 4NUT0080A (MF20 Series), 4NUT0114A (MLC20/MLD20 Series), 4NUT0093A (MRA Series). The recommended temperature is at or near 15 degree C (59 degree F).
When applicable, test the comfort function of the harness. Put the Mask Regulator onto the head per normal operation. This indicates that the harness is leak-tight in the inflated condition. NOTE: When applicable, make sure that the blinker on the stowage box turns yellow and then black, within a few seconds. Manually make sure that there is no internal bonding of the harness tubes in the folding areas. Eros Quick Donning Mask Free And UnrestrictedTurn the control knob back to its original position. Breathing should be free and unrestricted. Set the control knob to Emergency position. NOTE: The following test must be performed with the "N/100%" dilution control in the "100%" position. (b) Condition The Table 1 hereafter lists the most frequently observed causes of scrapping. NOTE2: Each sub-assembly is tagged with a manufacturing date to make easy the check of these periodicities (Refer to Fig 6 to 11). The deterioration of harness braid, supply hose braid, silicone tube used on these sub-assemblies, silicon seal tear and wear on the mask are potential causes of inappropriate pilot protection during emergency conditions. Those parts have been endurance tested through cycles, which showed evidence of these limits based on intensive use of the product. To permanently guarantee TSO* performances, ZODIAC AEROTECHNICS recommends strongly the replacement of the following sub-assemblies: * (technical Standard Order) (a) Periodicity Supply hose DTS4xxx Series, DTS4xxxG Series, DTSA Series: every 144 months, Harness MXH Series, MXHA Series: every 72 months, NOTE1: The above periodicities are based on ZODIAC AEROTECHNICS know-how and repair analysis as it is quite difficult for repair technicians to determine the serviceability of the subassembly in relation with ageing conditions which are not only visual.
