Cover those holes!Mechanics, when you remove the universal tracking device (UTD UTD United UTD University of Texas at Dallas UTD Up to Date UTD United Teachers of Dade UTD Uniform Theory of Diffraction UTD Uniform-geometrical Theory of Diffraction UTD Urban Thermo Dynamics (hip hop) UTD Unit Training Device ) camera, NSN NSN National Stock Number NSN Nokia Siemens Networks NSN National Storytelling Network NSN NATO Stock Number NSN New Substances Notification (CEPA) NSN National Student Number (NZ) NSN Never Say Never 6210-01-348-8252, from the AH-64D AH-64D Apache Attack Helicopter, D version, with Longbow radar improvements left extended forward avionics bay (EFAB EFAB Electrochemical Fabrication (micro-device manufacturing technology) EFAB Economic and Financial Analysis Branch (MMS Canada) EFAB Extended Forward Avionics Bay (aviation) ) and put it back into the vibration analysis kit, NSN 6625-01-282-3746, don't leave the four holes in the left EFAB cowling uncovered. Before you park your bird outside, make sure the holes are covered after rotor track and balance. Use hole hardware, NSN 5306-01-328-9219, and not the UTD camera attachment hardware. If the four holes are not covered and the bird sits outside in rainy weather, that's not good. Rain leaks through the holes where the UTD camera sits and into the open vent on top of the target acquisition designation sight (TADS) electronic unit, NSN 1680-01-452-9900. That water can short out the TADS and make your bird NMC. When camera is removed, put correct hardware in holes Make sure hardware does not make contact with TADS electronic unit |
