WEBVTT 00:25.819 --> 00:27.986 AM two . We need to finish the special 00:27.986 --> 00:30.041 inspections . How about you go ahead 00:30.041 --> 00:32.097 and apply CBC and the fact also that 00:32.097 --> 00:36.020 one , I'll use the spray 00:36.060 --> 00:38.227 time C PC because it will be faster to 00:38.227 --> 00:40.700 apply . We hold up A two . Are you sure 00:40.709 --> 00:43.069 that's the proper C PC for that 00:43.080 --> 00:45.799 application ? Well , I have one . What 00:45.810 --> 00:49.049 CBC am I supposed to use ? Oh , let's 00:49.060 --> 00:50.580 see what the dark says . 00:55.909 --> 00:58.470 The MDR states do corrosion protection 00:58.479 --> 01:01.000 on all s fastener holds fasteners and 01:01.009 --> 01:04.180 receptacles for door 159 . Ok . Let's 01:04.190 --> 01:07.150 verify in the now there 01 tech one 01:07.180 --> 01:10.779 alpha tech 509 volume two to see what 01:10.790 --> 01:13.239 we use for C PC for that . Now 01:14.730 --> 01:17.059 see here a page six tech eight 01:17.069 --> 01:20.650 paragraph K , the N A 01 tech one alpha 01:20.819 --> 01:23.730 tech 509 volume two states to install 01:23.739 --> 01:25.850 fasteners as directed by the aircraft 01:25.850 --> 01:27.809 maintenance manual . If no other 01:27.819 --> 01:29.708 directions are provided , install 01:29.708 --> 01:31.449 fasteners wet with corrosion 01:31.459 --> 01:34.230 preventative compound mill er F 01:34.239 --> 01:38.099 16173 grade four or core band 01:38.209 --> 01:41.879 27 L core band 27 L is not 01:41.889 --> 01:44.111 approved from this platform , but it is 01:44.111 --> 01:46.167 approved on several others . Consult 01:46.167 --> 01:48.278 your local maintenance and structural 01:48.278 --> 01:50.540 manuals for authorized use and two . Do 01:50.550 --> 01:53.839 you have the mill prep ? 1617 , 3 grade 01:53.940 --> 01:56.339 four . Yes , I am one . I have the mil 01:56.580 --> 02:00.250 pref 1617 3 grade four CBC right here . 02:00.580 --> 02:02.802 Good . Now continue to reference the NA 02:02.802 --> 02:06.489 A 01 T one alpha T 509 volume two to 02:06.500 --> 02:10.300 see how to apply the mill pr F-16 17 02:10.309 --> 02:14.229 3 grade four C PC and one I see 02:14.240 --> 02:17.589 here that mill prep 1617 3 grade four 02:17.600 --> 02:21.059 CBC can be applied with a brush on a 02:21.070 --> 02:24.160 dry surface . Yes , I am too . Just to 02:24.169 --> 02:26.169 ensure all your personal protective 02:26.169 --> 02:29.949 gear PV is installed and you have 02:29.960 --> 02:32.539 your verified against the proper SDS . 02:36.559 --> 02:38.392 Good job , am too . You properly 02:38.392 --> 02:40.880 applied C PC to all the faster rules . 02:41.289 --> 02:43.345 Now don't forget to let see all your 02:43.345 --> 02:45.509 fasters in accordance with the MD A T 02:46.320 --> 02:48.139 pad slash items 02:55.330 --> 02:59.210 and one we used mil prep 1617 , 3 02:59.220 --> 03:02.089 grade four C PC on the fastener holes 03:02.100 --> 03:03.878 and fasteners through the panel 03:03.878 --> 03:05.878 installation . What are these CP CS 03:05.878 --> 03:08.820 used for ? Let's see their exact uses 03:08.830 --> 03:11.490 in the NAB area . 01 P one out P five 03:11.500 --> 03:12.789 or nine volume two 03:16.440 --> 03:19.250 P CS are divided into water displacing 03:19.259 --> 03:22.460 and nonwater displacing CBC S the mill 03:22.470 --> 03:26.190 Pr F-16 17 3 grade four is a nonwater 03:26.199 --> 03:29.270 displacing CBC . Now , if you look at 03:29.279 --> 03:31.470 the two spray cans you have there AM 03:31.479 --> 03:33.770 two , those are both water displacing 03:33.779 --> 03:37.720 CP CS but have different intended uses . 03:37.880 --> 03:41.139 The MRF 81 03:41.149 --> 03:44.990 309 type two is a water displacing C PC 03:45.000 --> 03:46.667 used for short term corrosion 03:46.667 --> 03:49.949 prevention and in services , corrosion 03:49.960 --> 03:52.850 protection of moving parts where some 03:52.860 --> 03:56.690 lubrication is required . The mill 03:56.699 --> 03:57.669 pr F 03:58.470 --> 04:02.309 81309 tech three CBC 04:02.490 --> 04:05.330 is also water displacing CBC but is 04:05.339 --> 04:07.369 intended for usage for avionics 04:07.380 --> 04:09.580 equipment , electrical connectors and 04:09.589 --> 04:10.600 contact pins . 04:14.300 --> 04:16.739 Now I understand why we have different 04:16.750 --> 04:20.190 CP CS and how to determine the intended 04:20.200 --> 04:22.959 uses of each C PC to get the best 04:22.970 --> 04:25.192 results for aircraft , for protection . 04:25.410 --> 04:27.577 And two just remember that each faster 04:27.577 --> 04:29.799 that is installed onto an aircraft must 04:29.799 --> 04:32.179 have C PC applied to the attaching 04:32.190 --> 04:34.500 hardware in accordance with males and 04:34.510 --> 04:38.279 the data 0115 N 04:38.500 --> 04:41.279 one . I can see how that correction 04:41.329 --> 04:43.910 when in so fast as you can see , we see , 04:44.369 --> 04:46.989 I now feel more comfortable using the 04:47.000 --> 04:49.769 MD head slash fema and the NV 04:50.519 --> 04:52.880 01 attack one alpha attack 509 . 04:55.519 --> 04:58.079 As a maintainer , you need to be aware 04:58.089 --> 05:01.230 of chapter eight in the N A 01 T one 05:01.239 --> 05:03.589 alpha T 509 volume two , cleaning and 05:03.600 --> 05:06.040 corrosion control manual . This chapter 05:06.049 --> 05:08.216 gives you direction on the description 05:08.216 --> 05:11.029 of CP CS time limitation intended uses 05:11.040 --> 05:13.730 and applications methods for corrosion 05:13.739 --> 05:16.820 preventative compounds or CBC S to use 05:16.829 --> 05:19.420 on aircraft . Always refer to your MD 05:19.690 --> 05:21.912 or maintenance manual for directions on 05:21.912 --> 05:24.549 CBC to use when installing the faster 05:24.950 --> 05:27.228 if no specific instructions are listed . 05:27.359 --> 05:31.329 Follow the NA A 01 T one alpha T 509 05:31.339 --> 05:32.720 manual for CBC . 05:35.549 --> 05:37.382 Following maintenance procedures 05:37.382 --> 05:39.105 correctly ensures the aircraft 05:39.105 --> 05:41.049 operational and ready for use when 05:41.049 --> 05:43.649 needed . Remember , Rosa never sleeps . 05:43.880 --> 05:46.190 This is a one P siding out . See that 05:46.239 --> 05:46.619 new ocean .
