NDT Inspection of RFQ Main Landing Gear H-Frame

1. Method and Technique. Wet-Fluorescent Oil Based Magnetic Particle with Yokes.

2. Materials. The required equipment and consumable materials are listed in table 1.

Item Part Number Isopropyl Alcohol N/A

Lint-free rags N/A Magnetic Particle Aerosol Can (Fluorescent, Oil) AMS 3046

Magnifier 2-10x N/A Portable Yoke Parker Probe DA-200 or equivalent

Table 1. Required Materials.

3. Inspector Certifications. Inspectors operating to this procedure shall be certified as a Level 2 or higher in accordance with (IAW) NAS-410 or ASNT CP-189.

4. Pre-cleaning. Remove all contaminants, soils and oils with isopropyl alcohol and a lint-free cloth.

5. Process Controls. Ensure the following process controls are performed and documented prior to inspection IAW 33B-1-2 (15 AUG 2019):

a. System Effectiveness Check of Aerosol Media with Portable Equipment

b. UV-A Black Light Intensity

c. Ambient Light Checks

6. Procedure. Perform precursory visual inspection under an adequate white light source of at least 100 lumens. Use magnification as required. Mark suspected defects for further evaluation.

Perform Wet-Fluorescent Oil Based Magnetic Particle Inspection in accordance with 33B-1-2(15 AUG 2019), WP 301 00 of all welds. Use DC current. Space the yokes so that the weld and 2-iches of the heat-affected-zone (HAZ) are covered.

7. Evaluation & Reporting. Evaluate IAW the acceptance & rejection criteria contained with WP 301 00. Defects will be reported to NASA AFRC prior to rework being authorized. A report of the inspection results will be prepared and furnished to NASA AFRC. At a minimum, the report shall contain:

WARNING

THE USE OF DIRECT CONTACT MAGNETIZATION IS NOT AUTHORIZED
