A. Protective Treatment of Aluminum (Optional)

Where chromic acid anodize, MIL-A-8625, Type I is specified, sulfuric acid anodize, nondyed andsealed, per MIL-A-8625, Type II, Class 1 may be substituted.

NOTE: Approval from Gulfstream Technical Operations is required prior to substitution since thereare items where sulfuric acid anodizing may be questionable as a substitution (parts withjoints, seams, recesses, etc. that could entrap fluids or parts that will be adhesive bonded).

51-20-00Page 4February 29/04

Page 5: STRUCTURAL REPAIR MANUAL PROCESSES — GENERAL · 2. Finishes, Processes and Nondestructive Test (NDT) Inspection — Methodology and Equipment A. Protective Treatment of Aluminum

Where Alodine 1000 is called out on drawings, sulfuric acid anodize, nondyed, unsealed, per MIL-A-8625, Type II, Class 1 may be substituted.

NOTE: Restricted to stair treads and associated hardware.

Where Alodine 1000 or MIL-C-5541, Class 1A is specified Alodine 600 may be substituted.

Where Alodine 600 / MIL-C-5541, Class 3 is specified, Alodine 1200 may be substituted.

NOTE: In order to maintain an equivalent electrical conductivity with the Alodine 1200 finish it iscritical that the proper solution concentrations and immersion dwell times per chromateconversion coating of aluminum alloys be adhered to. See Chromate Conversion Coating ofAluminum Alloys, 51-21-00, Repair.

B. Cadmium Plating of Steel Parts (Optional)

Where electro-deposited cadmium plating per QQ-P-416 is specified, vacuum deposited cadmiumplating per MIL-C-8837, Type II, Class 2 may be substituted.

NOTE: Vacuum cadmium plating of all steel parts heat treated above 180,000 psi requiresGulfstream Technical Operations review and approval.

When vacuum cadmium plating is utilized, parts must pass a dry tape adhesion test usingfresh (less than 6 months old) 3M No. 254 tape. Parts failing this test shall be stripped andreprocessed to attain satisfactory adhesion.

C. Age Control of Elastomeric Material (Mandatory)

Age sensitive elastomeric materials must meet the requirements of MIL-STD-1523.

D. Surface Finish Requirements

Surface roughness of routed sheet metal edges (mandatory) - Unless otherwise specified on theengineering drawing, all routed sheet metal edges shall be finished to 125 RMS.

E. Nondestructive Tests

Nondestructive Test (NDT) inspection procedures (methodology and equipment).

NOTE: Refer to GIV NDT Manual for inspection procedures.

F. Hardness Testing of Metals

Procedure - Hardness tester verification (to be performed by qualified personnel).

– Testers with Rockwell or Brinell scales shall be verified by using the correct side of a standardtest block on each instrument at the beginning of each investigation. Each time a new scale isused, it shall also be verified by the specific test block.

– Conductivity meters shall be operated only by qualified individuals who are well conversed withaerospace NDT procedures. Instrument calibration verification via standards attached to eachmeter shall constitute proper preliminary equipment testing.

Operation - Testers with Rockwell, Brinell and Barcol Scales:

NOTE: Surface finish is essential for obtaining accurate readings against the parts in question. Theprepared surface should not exceed (RMS) ME4V SQ 125 and or 125 micro inches orbetter.

– Valid hardness readings require proper combination of load and penetration, correct anvil and asmooth, flat, properly prepared surface normal to the axis of the indenter. See Figure 1 andFigure 2.

– Reading shall be taken in areas where indentations cannot later contribute to failure. Only

material that will not be destroyed or mutilated beyond serviceability shall be tested by thismethod.

– Limit the number of indentations to the minimum necessary for accurate determination.– When testing curved surfaces correction factors must be added.– When a part cross section is relatively constant, hardness may be determined by a single

reading.– When part cross section changes significantly or when a narrow hardness range is required,

three readings are taken and averaged.– When three Rockwell readings are taken, they must be within two hardness points of each

other.– When three Brinell readings are taken, they must be within 20 hardness points of each other.– When evidence of a hardness indentation in contact with an anvil is observed on the reverse

side of the part, the hardness reading is not valid.– When decarburization or other surface condition is suspected of causing erroneous readings,

the surface condition can be removed provided the part tolerance is not exceeded.

Valid conductivity readings require a smooth, flat surface normal to the axis of the probe.

Requirements

– Table 3 establishes Rockwell correction factors which are added when testing convexcylindrically curved surfaces.

– Table 4 established minimum material thickness for each Rockwell hardness scale.– Table 5 establishes approximate equivalent Rockwell hardness values for steel.– Table 6 establishes approximate equivalent Rockwell hardness values for wrought aluminum.– Table 7 establishes Rockwell and Brinell hardness values for the following:

Wrought carbon steels (1015, 1018, 1020, 1025, 1065, 1095, drill rod and hi-carbon musicwire).Wrought low alloy steels (3312, 4130, 4140, 4330 Va. Modified, 4340, 6150, 8740, D6 AC,Graph-Mo, H-11 and hy-tuff).Wrought Martensitic stainless steels (410, 416, 420, 431 and 40-G).

– Table 8 establishes hardness to tensile strength values for wrought carbon and low alloy steels.– Table 9 establishes hardness requirements for wrought aluminum alloys.– Table 10 establishes electrical conductivity requirements for wrought aluminum alloys.– Table 11 establishes hardness requirements for aluminum alloy and magnesium alloy castings.– Table 12 establishes hardness requirements for wrought precipitation hardening, corrosion and

heat resistant alloys.– Table 13 establishes hardness requirements for copper alloys.– Table 14 establishes hardness requirements for titanium alloys.– Other approved type hardness testers may be used in accordance with the manufacturer’s

data.

Laboratory tensile testing - When the hardness check is carried out on a fire damaged structure andis inconclusive, a section of the damaged structure must be cut out and tensile tested to determinethe serviceability of the remaining part of the structure. When sending parts or samples to thelaboratory for analysis, include a descriptive report about the type and duration of the fire.

NOTE: Gulfstream Technical Operations review and approval required.

NOTE: Hardness values do not provide a basis for verifying conformance to mechanical propertiesin applicable specifications or rejecting parts. Hardness values in excess of those indicatedmay be used to screen parts for material in STA condition or presence of alpha case.

The effect of heat on Titanium cannot be evaluated properly by hardness tests to evaluatethe properties of Titanium accurately, a metallurgical examination must be made. However,Titanium surfaces oxidize and change color with increasing heat and scale at hightemperatures. This characteristic can be used to assess the intensity of the heat imposedon the Titanium structure. Gulfstream Technical Operations review and approval required.
