Thank you for everything 01:24.816 --> 01:25.982 you do . God bless . 01:33.500 --> 01:36.019 Aircrew walk around flight inspection . 01:36.550 --> 01:38.661 Hi , I'm Commander Joe Gersy callsign 01:38.661 --> 01:40.772 Man Bear Pig . I'm the safety officer 01:40.772 --> 01:42.439 here at VFA 106 . Hello , I'm 01:42.439 --> 01:44.550 Lieutenant Dean Corbett , callsignagg 01:44.550 --> 01:46.717 man , and I'm an instructor pilot here 01:46.717 --> 01:48.510 at VAW 120 . Hello , my name is 01:48.510 --> 01:50.566 Lieutenant Commander Dickin Counts , 01:50.566 --> 01:52.566 HSE2 , and I'm an air crew training 01:52.566 --> 01:54.650 officer . This video will point out 01:54.650 --> 01:56.706 some common areas that you will most 01:56.706 --> 01:58.680 likely encounter corrosion while 01:58.680 --> 02:00.902 performing a pre-flight , post-flight , 02:00.902 --> 02:02.847 or pilot weekly inspection and the 02:02.847 --> 02:05.013 proper procedures required to document 02:05.013 --> 02:07.779 the corrosion when found . Early 02:07.779 --> 02:09.612 identification and treatment are 02:09.612 --> 02:11.612 crucial components in the corrosion 02:11.612 --> 02:13.501 prevention and control process to 02:13.501 --> 02:15.223 prevent further damage and the 02:15.223 --> 02:17.168 necessity for structural repairs . 02:17.168 --> 02:18.946 Naval aircraft are continuously 02:18.946 --> 02:20.946 subjected to corrosive environments 02:20.946 --> 02:23.112 such as rain , salt water , humidity , 02:23.112 --> 02:25.223 dust , direct sunlight , and aircraft 02:25.223 --> 02:27.279 fluids , which can lead to extensive 02:27.279 --> 02:29.223 corrosion , dry rot , and possible 02:29.223 --> 02:31.830 equipment failure . First , we'll start 02:31.830 --> 02:34.110 off at AS Oceana . We'll start our 02:34.110 --> 02:36.054 review of the corrosion inspection 02:36.054 --> 02:38.470 process with the FAA . Starting at the 02:38.470 --> 02:40.637 nose landing gear , we are looking for 02:40.637 --> 02:42.692 corrosion and exposed metal that can 02:42.692 --> 02:44.859 lead to corrosion . It is important to 02:44.859 --> 02:46.748 look at all wire clamps and clamp 02:46.748 --> 02:48.637 sheathing for damage . Damaged or 02:48.637 --> 02:50.692 missing sheathing can cause friction 02:50.692 --> 02:52.526 and contact of dissimilar metals 02:52.526 --> 02:54.303 contributing to corrosion . The 02:54.303 --> 02:56.137 inspection criteria for the main 02:56.137 --> 02:58.303 landing gear is similar to that of the 02:58.303 --> 03:00.470 nose landing gear . The intake is made 03:00.470 --> 03:02.359 up of dissimilar metals and other 03:02.359 --> 03:04.192 materials that can contribute to 03:04.192 --> 03:06.414 corrosion . The combination of aluminum 03:06.414 --> 03:08.414 substructure covered with composite 03:08.414 --> 03:10.470 skin , fastened with stainless steel 03:10.470 --> 03:12.637 fasteners , creates a corrosion cell . 03:12.750 --> 03:14.528 A topcoat is applied to prevent 03:14.528 --> 03:16.361 electrolytes from contacting the 03:16.361 --> 03:18.399 dissimilar materials , but cracks , 03:18.520 --> 03:20.679 chips , and imperfections in the 03:20.679 --> 03:22.846 coatings can lead to corrosion if they 03:22.846 --> 03:25.389 are not quickly corrected . Lollipop 03:25.389 --> 03:28.110 links are on all aircraft TMS and are 03:28.110 --> 03:30.429 highly susceptible to corrosion because 03:30.429 --> 03:32.429 the bearings function best when not 03:32.429 --> 03:35.000 painted . Connecting links are utilized 03:35.000 --> 03:36.833 for several different systems on 03:36.833 --> 03:40.009 aircraft . Antenna areas can be a major 03:40.009 --> 03:41.787 contributor to corrosion if not 03:41.787 --> 03:44.059 properly sealed . Improper application 03:44.059 --> 03:46.410 of stealing or lack of sealan on the 03:46.410 --> 03:48.970 antenna mount mold line junctions leads 03:48.970 --> 03:51.081 to water and contaminant intrusion to 03:51.081 --> 03:53.026 the substructure , contributing to 03:53.026 --> 03:55.248 corrosion and costly airframe repairs . 03:55.470 --> 03:57.526 The last area we will discuss is the 03:57.526 --> 03:59.649 windscreen canopy area . Corroded 03:59.649 --> 04:01.760 windscreens can lead to discrepancies 04:01.760 --> 04:03.538 that require costly depot level 04:03.538 --> 04:05.260 maintenance to repair , if not 04:05.260 --> 04:07.427 documented and corrected immediately . 04:07.440 --> 04:09.384 Now let's head over to NAS Norfolk 04:09.384 --> 04:11.551 flight line for additional information 04:11.551 --> 04:13.773 on E2D and H60 aircraft corrosion prone 04:13.773 --> 04:16.429 areas . Aircraft landing gear systems 04:16.429 --> 04:18.485 are constructed of varying materials 04:18.549 --> 04:20.605 such as high strength steel alloys , 04:20.605 --> 04:23.070 aluminum alloys , and cadmium plating 04:23.070 --> 04:25.059 with attaching steel fasteners and 04:25.059 --> 04:27.309 hardware . Cadmium plated attaching 04:27.309 --> 04:29.476 hardware will start to lose its golden 04:29.476 --> 04:31.587 appearance if it is corroded and will 04:31.587 --> 04:33.420 appear dull , dark , or rusted . 04:33.420 --> 04:35.365 Landing gear struts and peripheral 04:35.365 --> 04:37.476 components are susceptible to chipped 04:37.476 --> 04:39.698 paint and exposed metal caused by small 04:39.698 --> 04:41.865 rock strikes . The degraded coating on 04:41.865 --> 04:43.698 these critical parts can lead to 04:43.698 --> 04:45.642 corrosion that may be difficult to 04:45.642 --> 04:47.529 detect and may lead to premature 04:47.529 --> 04:50.329 failure . One area we will inspect is 04:50.329 --> 04:53.089 the E2D center wing . This large area 04:53.089 --> 04:55.119 has multiple access panels that are 04:55.119 --> 04:57.397 prone to chipped paint , exposed metal , 04:57.410 --> 04:59.299 and galvanic corrosion around the 04:59.299 --> 05:01.290 fastener heads . We also want to 05:01.290 --> 05:03.489 inspect for proper sealant integrity 05:03.489 --> 05:05.656 around the panels to minimize moisture 05:05.656 --> 05:07.378 intrusion into the center wing 05:07.378 --> 05:09.839 structure . This inspection methodology 05:09.839 --> 05:11.929 also applies to the horizontal and 05:11.929 --> 05:15.790 vertical stabilizers . Engine cells 05:15.790 --> 05:17.623 are subjected to constant debris 05:17.623 --> 05:19.512 strikes as well as self-inflicted 05:19.512 --> 05:21.623 damage from the use of hand tools and 05:21.623 --> 05:23.910 ladders . Naval aircraft that conduct 05:23.910 --> 05:26.299 low-level missions over salt water are 05:26.299 --> 05:28.021 exposed to extensive saltwater 05:28.021 --> 05:30.070 intrusion that can lead to very 05:30.070 --> 05:32.149 expensive corrosion repairs if not 05:32.149 --> 05:34.190 detected and corrected in a timely 05:34.190 --> 05:37.730 manner . On the exterior , we will look 05:37.730 --> 05:40.359 for corroded fasteners around the pilot 05:40.359 --> 05:43.299 and co-pilot windscreens , windows , 05:43.480 --> 05:45.369 windshield wiper assemblies , and 05:45.369 --> 05:48.600 inspect for seal and integrity . A 05:48.600 --> 05:50.880 common and costly corroded area in the 05:50.880 --> 05:53.519 nose eBay is the mating surface of the 05:53.519 --> 05:55.989 nose door . Pay close attention to the 05:55.989 --> 05:58.279 seal in this area . Door mating 05:58.279 --> 06:00.239 surfaces are significant corrosion 06:00.239 --> 06:03.959 prone areas . Inside the cockpit , 06:04.130 --> 06:06.186 we will look at the deck fasteners , 06:06.290 --> 06:08.670 window anchor nuts , restraint buckle 06:08.670 --> 06:10.890 assemblies , and the overall condition 06:10.890 --> 06:13.720 of the center console . Upon completion 06:13.720 --> 06:16.049 of walk around flight inspection , it 06:16.049 --> 06:18.450 is important and essential to document 06:18.450 --> 06:20.809 all the discrepancies found . When 06:20.809 --> 06:22.476 creating a work order for the 06:22.476 --> 06:24.587 discrepancies found , it is important 06:24.587 --> 06:26.769 to use the proper codes . The first 06:26.769 --> 06:29.489 code to note is the when discovered 06:29.489 --> 06:32.609 code . The main codes used for pre-post 06:32.609 --> 06:36.130 flight are A before flight abort 06:36.450 --> 06:39.959 B before flight , no abort , D 06:40.170 --> 06:43.839 inflight , no abort , E after flight 06:44.209 --> 06:48.010 between flight F pilot NFL inspection . 06:49.010 --> 06:51.010 The next code that is important for 06:51.010 --> 06:53.320 documenting pre post flight corrosion 06:53.320 --> 06:56.579 is type work order codes . Type work 06:56.579 --> 06:59.540 order code DF should be selected . When 06:59.540 --> 07:01.207 maintenance discrepancies are 07:01.207 --> 07:02.984 discovered during pre-flight or 07:02.984 --> 07:05.829 post-flight inspections . The last code 07:05.829 --> 07:07.959 we will discuss for aircrew use for 07:07.959 --> 07:10.559 documenting corrosion is type 07:10.559 --> 07:13.000 maintenance code . B unscheduled 07:13.000 --> 07:15.167 maintenance . It is important to write 07:15.167 --> 07:17.320 work order discrepancies in a manner 07:17.320 --> 07:19.480 that the maintenance team can clearly 07:19.480 --> 07:21.959 understand and easily find in order to 07:21.959 --> 07:23.903 treat the specific corroded area . 07:24.720 --> 07:27.959 Pilots , NFOs , and air crews serve an 07:27.959 --> 07:30.070 important role in the overall success 07:30.070 --> 07:32.126 of a squadron's corrosion prevention 07:32.126 --> 07:34.600 and control program . Your squadron 07:34.600 --> 07:36.711 training officer will provide further 07:36.711 --> 07:38.822 guidance for corrosion prone areas on 07:38.822 --> 07:41.850 your specific type , model , series , 07:42.079 --> 07:44.920 aircraft . In closing , frequent 07:44.920 --> 07:47.087 corrosion inspections are essential to 07:47.087 --> 07:49.309 the overall corrosion control program . 07:49.619 --> 07:51.786 The costs resulting from corrosion can 07:51.786 --> 07:53.730 be minimized by early detection , 07:53.980 --> 07:56.260 identification , and treatment . 08:05.390 --> 08:08.100 We at Micro Learning , taking the 08:08.100 --> 08:09.890 training to the next level .
