19. What is the shorter part of a formed angle?

45. Can interfere with the operation of the aircraft's electrical and electronic systems by coupling electromagnetic energy to the system wiring and components

46. What is increasingly dependent upon electrical/electronic systems, which can be susceptible to electromagnetic interference?

47. What are highly susceptible to HIRF?

48. What is increasing in number and in power. 

49. Airframe Skin and Frame

50. LRU case, Electronics Input Output Protection

52. What is the first and generally most important step in HIRF maintenance?

53. What is the most easily detected sign of an excessive load having been imposed during a landing? 

54. What should be performed after a flight through severe turbulence?

55. What material may soften the fabric or loosen the fabric tapes of fabric covered aircraft?

56. What can cause damage to the aircraft both visible and hidden?

57. What may occur if the aircraft is not parallel to the runway when it lands or if the nose- or tail-wheel strikes the runway before the main wheels?

58. What may be expected following a heavy landing would normally be concentrated around the landing gear?

59. What may be found on the fuselage upper and lower skins and on the wing skin and structure?

60. What should be examined for creep, damage, and cuts?

20. What is given on the drawing or blueprint or may be obtained from the original part?

21. What can be replaced with another brake radius bar with a different diameter?

22. Lay out the basic part using ________ layout procedures. 

23. Is often tangent to the radius and perpendicular to the edge

24. What are the present unique problems that require more calculations than 90° bends? 

25. If the flange is to be shrunk, place the flange across the ____.

26. Parts are usually hand formed with a concave flange, the inside edge, and a convex flange, the outside edge. 

27. It is formed by stretching, while the convex flange is formed by shrinking.

28. only one large convex flange is used

29. It is difficult to form, but the outside flange is broken up into smaller sections by relief holes.

30. These are placed at equally spaced intervals to absorb material and cause curving. 

31. What is formed by crimping, beading, putting in relief holes, and using a formed angle riveted on each end?

32. What is formed by shrinking the material over a form block?

33. What can be done on a form block or female die, or on a sandbag?

34. Designed for form block bumping must have the same dimensions and contour as the outside of the blister

35. What is one of the most difficult methods of hand forming sheet metal because there is no exact forming block to guide the operation?

36. What can cause visible damage, like small circular holes on the aircraft external skin?

37. What is designed to withstand repeated landings within an aircraft weight limit and within a vertical descent speed limit?

38. It is only performed after abnormal events, which could possibly have caused damage to the aircraft or impaired the airworthiness.

39. After an extremely hard landing or other unusual loads on the landing gear.

40. For damage evaluation consult the manufacturer, before the aircraft is put back into service.

41. When performing any abnormal event inspection, always follow the detailed procedures in the aircraft maintenance manual.

42. During the service life of an aircraft, occasions may arise when something out of the ordinary care and use of the aircraft might happen that could possibly affect its airworthiness. 

43. Visual inspection is the first and most important step that is often sufficient to find the deterioration of the protective features.
