18 16.10.00 APPENDIX V: STRUCTURAL INTEGRITY TESTING OF THOROUGHBRED GRAND PRIX CARS

1. The following items of a Thoroughbred Grand Prix Car must be checked for structural integrity by a non-destructive test: 6. The test certificate/manufacturer's declaration must be a) Road wheels constructed from or containing magnesium parts. appended to the Historic Vehicle Identity Form. b) Road wheels constructed from cast aluminium (N.B. spun or machined aluminium parts or components are exempted). 7. It is strongly recommended that similar inspections should be c) Suspension wishbones, rockers and push/ pull rods. carried out on components that are vital to the integrity of the car d) Steering arms but which may not be contained in the list above. e) Wheel hubs. f) Suspension uprights, whether cast or fabricated. 8. The tests must be carried according to the following standards: 2. All of the above components must be tested using a method BSI, DIN, ISO, ASTME of crack detection appropriate to the material and type of Penetration Flaw Detection construction of the component in question. Each component BS 6443 and BSM 39, DIN 54152-1, ISO 3452 must be identified by having the type and chassis number of the Magnetic Particle Flaw Detection corresponding vehicle indelibly etched or marked on it: chassis BSM 34, ASTME 709 n°/ part identification / part n°. The following method of identifying X-Ray Flaw Detection the components must be used: BS 6072 and BSM 35, DIN 54111-1, DIN 54111-2, ISO 5579.

Wishbone, left front = WLF Rocker arm, left front = RLF Wishbone, right front = WRF Rocker arm, right front = RRF Wishbone, left rear = WLR Rocker arm, left rear = RLR Wishbone, right rear =WRR Rocker arm, right rear = RRR (specify upper or lower)

Push/pull rod, left front = PLF Upright, left front = ULF Push/pull rod, right front = PRF Upright, right front = URF Push/pull rod, left rear = PLR Upright, left rear = ULR Push/pull rod, right rear = PRR Upright, right rear = URR

Hub, left front = HLF Hub, right front = HRF Hub, left rear = HLR Hub, right rear = HRR

Steering arm, left = SAL Steering arm, right = SAR

Wheel, front = WHF Wheel, rear = WHR

3. The company or establishment responsible for verifying the structural integrity of components must furnish the vehicle owner with a certificate or letter on official headed notepaper (photocopies are not acceptable) certifying that they have tested the components listed upon the certificate. The parts fitted on the vehicle must at all times correspond to those listed on the certificate. The certificate or letter should bear the name and signature of the inspector and the date upon which the inspection was carried out. Spare components intended for use on the vehicle must also be inspected accordingly and should be detailed on the certificate.

4. The certificate will be valid for a period of 2 years from the date of testing.

5. New components: components declared and certified as new by the manufacturer will be exempted from testing for a period of 2 years from the stated date of manufacture except in the case of magnesium road wheels which will be exempt for a period of 3 years from the date of manufacture.

19 16.10.00 APPENDIX VI: CHECK AND REPAIR OF COMPOSITE STRUCTURES

Any repairs to the survival cell or nosebox must be carried out in accordance with the manufacturer's specifications, in a repair facility approved by the manufacturer. If this is not possible, all repairs must be carried out in accordance with the following in a facility approved by the FIA.

1. There are four types of damage which can be effectively repaired: 1.1 Indentation causing deformation to both skins. Repairs can generally be economically considered up to 250cm2 of any one area. 1.2 Penetration through the outer skin causing deformation of inner core. Repairs can generally be economically considered up to 20% of the total area of the monocoque. 1.3 Areas of delamination. Repairs can generally be economically considered up to 20% of the total area of the monocoque. 1.4 Penetration through the entire sandwich structure. Repairs can be satisfactorily carried out up to 125cm2 of any one damaged area.

2. Testing composite structures: 2.1 In the absence of ultra-sonic testing equipment a simple coin test will suffice. 2.2 Check for delamination around periphery of the damaged area by tapping the skin with a small metallic object such as a small coin. There is a hollow sound from a delaminated area compared to a ringing-solid sound from non-damaged area.

3. Repair procedures: 3.1 Examine the damaged area. 3.2 Remove the damaged skin by making a hole, as circular as possible without cutting away an excessive amount of sound material, and cut out the damaged honeycomb core down to the other skin. if both skins are damaged, select the one with the largest area of damage. 3.3 Sand out a circular or oval dish-shaped area of face laminate, with a uniform taper around the damaged or removed area, to approximately 10cm from the edge of the area. 3.4 Wash out any dirt or sanding dust with acetone or similar. 3.5 Trim the honeycomb and make a plug which will fit into the prepared cavity. Place adhesive film or resin mixture on sound skin at base of cavity and a foaming paste around its periphery. Take the plug and insert it into the cavity pressing hard enough to squeeze resin into the honeycomb core. 3.6 Cut replacement plies to the shape of the area making each bigger than the previous one until the final ply is approximately 10cm bigger around the circumference of the repair area. 3.7 Place release film and bleed cloth over the new laminate and put sticky tape around the repaired area, cover with a vacuum membrane and evacuate. Maintain a minimum of 500mm of mercury vacuum during the cure cycle.

4. Cure Cycle: 4.1 The cure cycle is based on which materials are being used. 4.2 Successful repairs can be carried out cold if the repair is not greater than 50cm2 in any one area. Hot cures can be placed in an oven or can be carried out using a heat patch. 4.3 The procedures described can also be used in a suspension mounting area. 4.4 If only delamination has occurred, a number of 3mm diameter holes can be drilled around the delaminated area and then one injected with a two part cold set epoxy resin adhesive until the adhesive is evident in all holes. The holes must then be covered with release tape for the duration of the cure.
