SD3-60 STRUCTURAL REPAIR MANUAL z SRM 1.0.0.0FUSELAGE - STRUCTURAL IDENTIFICATION 1. Introduction This chapter indicates the location of the strcu tural members of the fuselage and shows methods for repairing minor damage to these members by either patching, fitting an insertion or replacing a member. If the repair is of a major nature Bombardier Aerospace (Belfast) will advise on method and procedure to carry out the repair and information can be obtained from Aerospace Customer Support on request from the operator. For procedure and application form refer to the INTRODUCTION to this manual. Refer to INTRODUCTION, pb1. 2. General The fuselage comprises a nose fuselage (-80 inches to 74 inches), main fuselage (74 inches to 472.5 inches) and a rear fuselage (472.5 inches to 741 inches) joined together with a fully manufactured rivetted joint. The main structural aperatures are for nose baggage compartment door (forward left), freight door (forward left), emergency exit (forward right), passenger door (rear left), emergency exit (rear right), rear baggage compartment door (rear left) and crew ditching hatch (forward top). Frames are located from a datum which is 3 inches forward of the bulkhead at the rear of the nose baggage compartment. Horizontal positions (H) are measured from the inside of the bottom skins on the parallel portion of the fuselage. Vertical positions (V) are measured from the centreline of the fuselage. 3. Nose Fuselage The nose fuselage contains the flight deck compartment, the nose landing gear bay and the forward baggage compartment. The construction is semi-monocoque of conventional skin and lipped angle stringers carried on channel and lipped frames. Materials used are L72 and L73. Forward of frame 3 inches, the nose profile is basically conical with the frames having a deep bottom member to support the baggage compartment floor at 8.2 inches H between frames -60 inches and 3 inches. Aft of frame 3 inches the profile expands to a rectangular shape with frames having top, side and bottom members. The bottom members are increased in depth to support the pilots floor at 23.96 inches H and end at the keel walls at 10.25 inches V each side of the fuselage centreline. The keel walls and pilots floor form the nose landing gear bay between frames 3 inches and 74 inches. Page 1
z SD3-60 STRUCTURAL REPAIR MANUAL Frame 3 inches has a top, bottom and side member. The bottom member being a continuous web which forms the forward wall of the landing gear bay and supports both the pilots floor and the baggage compartment floor. The frame is converted into a bird strike bulkhead by closing off the area above the pilots floor with a bonded sandwich construction of L72 sheet/aluminium foil honeycomb bolted to the frame. The stringers, which are located by a numbering system, run in cutouts in the frames and are attached with cleats and brackets to the frames and at their terminations. The upper and lower coupe rails are 7075-T6 material and the brackets for supporting the windshield pillars are L65 material. The windshield pillars are each constructed from two channel extrusions which are assembled and installed with bolts. These pillars are continued into the canopy with intercostal members of L72 material. 4. Main Fuselage The main fuselage extends over the length of the passenger seating area. It consists of a parallel rectangular box between frames 74 inches and 401.73 inches and a constant width section with a curved underside extending aft to frame 472.5 inches. frames, except the front and rear spar frames, have top, bottom and side members of L73 or 7075-T62 channel section reinforced as necessary with bonded doublers and additional boom angles. The frames are joined at the corners with L73 finger plates and the bottom members have increased depth to support the floor at 8.2 inches H. Outer flanges of frames are stabilised by rivetting through the crown of each corrugation and inner flanges are supported by light gauge L72 tension straps running fore and aft. Shear cleats attach the frames to the skin between each skin corrugation. The front and rear spar frames, at stations 274.17 inches and 300.77 inches respectively are fabricated from two flat web plates with separate boom angles. The top and side members are of L73 material and are joined at each corner with 7075-T351 fail-safe wing attachment brackets. Both spar bottom members extend beyond the side of the fuselage as part of a box structure to pick-up the main landing gear ribs. Each of these members consist of two flat 2024-T351 web plates sandwiched between two L73 finger plates, which extend over the entire length of the web and also form the joint with the side members. Double L65 angles form the inner and outer booms. The main landing gear and wing strut loads are carried on two 7075-T7351 ribs which are connected with L93 vertical web plates and attached to the ends of the spar frames at 59.975 inches V and 70.15 inches V. Heavy gauge L73 shear decks are attached to the upper and lower booms of the spar frames and extend from the outer rib to the fuselage side. The wing strut attachment brackets are L93 material. Page 2
SD3-60 STRUCTURAL REPAIR MANUAL z Generally the skin consists of double skin panels in which a smooth outer skin is bonded to corrugated inner sheet, both of which are L72 material. Vertical joints are closed with flat external and corrugated internal buttstraps attached with a double row of rivets at each side of joint. Inner skin corrugations have a.75 inch radius from the mating face and pitched at 3 inch intervals. The only areas in which conventional skin and stringer configuration is employed are at the window planks along each side of the fuselage, where L72 skins and angle stringers are used, and the curved underside of the fuselage aft of frame 401.73 inches, which uses L72 skins and top-hat stringers. The bottom corners of the fuselage are formed by mainly single curvature skins of heavier gauge L72 without internal stiffners. The floor seat rails run between frames 74 inches and 458 inches at 20.6 inches V left side and 8.4 inches V right side and are supported on diaphragms of L73 between frames. The side seat rail run 18.25 inches H between frames 146.2 inches and 428 inches left side and frames 89 inches and 428 inches right side of fuselage and are supported on 7075-T6 diaphragms intercostal with the frames. The wing fairings and fuel tanks form the upper profile of the aircraft. Forward and aft fuel tanks extend from stations 176 inches to 261.5 inches and from stations 319.15 inches to 375.85 inches respectively and are constructed from conventional skin, stringers and diaphragms of L72 material. Wing fairings are of L72 skin, stringer and frame manufacture and the forward fairing houses the airconditioning system. The main landing gear fairings are of moulded Kevlar reinforced plastic honeycomb construction. 5. Rear Fuselage The rear fuselage comprises the fuselage aft of frame 472.5 inches. It contains the toilet, attendant's station, galley, aft baggage compartment and support structure for the vertical and horizontal stabilisers and the fuselage tail fairing. The vertical frames have top and side members of flat webs and inner and outer boom angles of 2024-T42 material. The bottom members have been deepened to support the floors and consist of 2024-T3 or 2024- T42 webs with upper and lower boom angles. These frame members are lap joined at top and bottom corners. The skins are 2024-T3 throughout and are stiffened by 2024-T42 stringers. Except for the bottom skins forward of frame 566.5 inches, which have top-hat section, the stringers are of a Z section. stringers are attached by cleats to the frames. Page 3
z SD3-60 STRUCTURAL REPAIR MANUAL The top and bottom corners of the fuselage are formed by curved skins with no internal stiffeners. The floors are stepped to cater for the rise in bottom profile and are positioned at 13.8 inches H between frames 458 inches and frame 508 inches 24 inches H between frames 508 inches and frame 536.5 inches, 30 inches H between frames 536.5 inches and frame 566.5 and 34.7 inches H between frame 566.5 inches and frame 595 inches. The vertical and horizontal stabilisers support structure basically comprises three sloping bulkheads, the forward and rear of which are angled to suit the front and rear spars of the vertical stabilisers, and a horizontal shear deck which runs aft from the rear bulkhead at 80 inches H. These members consist of 2024-T3 webs with boom angles and main structural fittings of 2024- T3511. The support fittings for the horizontal stabiliser forward pick-up is located on the forward face of the rear bulkhead and is of 7075-T73510 material. Flanged stabilising diaphragms of 2024-T42 material are attached to stringers 57.5 inches H and 69.5 inches H between frame 620 inches and the centre sloping bulkheads on both sides of fuselage. The closing fairing at the stabilisers and fuselage intersection consists of a top Kevlar reinforced plastic fairing and side fairings of a sandwich construction of Kevlar reinforced plastic/nomex honeycomb with 2024-T62 stiffeners. 6.
