Task Instructions
1. Test the socket assembly in the wing by carefully rotating the wing tip to ensure proper engagement and retention of the pin.
CAUTION:
Be sure to support the wing in case of failure. The wing should move slightly but should not contact the Seawing.
2. Looking at the wing fold mechanism, ensure that all circlips and visible attachment points are fully secured. Evaluate the U-point pins and circlips.
3. With the wing fold mechanism exposed, actuate the wing fold handle to validate that there is full positive detent at the end of the handle rotation while also exhibiting smooth motion throughout the range. With the handle unlatched, check for excessive freeplay of the handle.
4. Visually inspect all fastening hardware to ensure it is secure and to ensure there is no missing hardware.
5. Confirm that the slide bushing assembly is still securely bonded in place and is not able to slide or rotate.
6. Ensure the extension cap spring is still fastened to the slide tube.
7. Validate that the wire harness is in good working condition and is free of any wear and tear.
8. Replace the wing access panel.
Verification Method
Completion of the steps above without any findings verifies proper security of the wing fold mechanism.
