I. Objective Checking the static strength of F-5.003 aircraft structure. II. Object of tests The item F-5.003 made by manufacturer, is an article of a customizing batch and is a modification of a serial aircraft F-5.001. The complete set of an article should correspond to the documentation, supplied with the aircraft. The item F-5.003 has the following differences from a prototype aircraft F-5.001: - Nose cone diameter is increased and nose cone angle of the installation is changed; - cockpit windows with improved in-flight view, - Tail part with the improved streamilining and sunk brake parachute, - Wing with new fairing and tip, the angle of leading edge=6; - Straightened axes of engines, - Rudders of increased area with reinforced fittings; - Capacity of fuel tanks is increased, - The number of suspensions is increased and their arrangement is changed. The new design weight is provided at the same nG. III. Technique of tests 1. Test of airframe components are condected on full-scale airframe in accordance with Test Assignments. 2. All tasks for static tests are drawn up in accordance with initial data given in “Loads on F-5 airframe spreadsheet“. 3. During tests, to produce measurements of deformations, stiffness, stresses should be produced according to the schemes issued by strength department. 4. The stages of tests and testing procedure are determined by special coordinated schedule. 5. After completion of tests, airframe disassembly(deriveting and cutting) should be condected for failure inspection of internal substructure. 6. During conducting the tests program, the approved refinements and additions to the program may be introduced.
