***Residual unbalance determined via U = 6GW/N, where G = 2.5 mm/s, W = 337 lbs and N = 853 RPMs (Source: MIL-STD-167-1A, paragraph 5.2.2.2).

7. Surface Inspection Document ALL defects on the following sheets. For the dye penetrant inspection, highlight/annotate ALL defects that fall outside of the allowable parameters set by ABS Part 7, Section 10, Table 1. Provide two sheets, one per face and label pages 5a and 5b.

NOTE: Photographs may be inserted in place of these inspection forms provided the photos collectively encompass the entire propeller and adhere to the instructions for documenting/highlighting/annotating defects. The photographs must be labeled such that the blades, hub locations and defect locations are identifiable. See the following page for the hub diagram.

LH Propeller Hub – Sketch and label the adjacent blades in the above diagram.

RH Propeller Hub – Sketch and label the adjacent blades in the above diagram.

NOTES: Use the above sketches multiple times to capture the hub sections between all blades. Photographs may be inserted in place of these inspection forms provided the photos collectively encompass the entire hub and adhere to the instructions for documenting/highlighting/annotating defects. The photographs must be labeled such that the blades, hub locations and defect locations are identifiable.

Signatures for the propeller hub sketches.
