AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect the piston and fork assembly using a 20-power enlarging lens, dye penetrant, or magnaflux. If cracks exist, rework by grinding within specified limits (e.g., up to 0.065 inch depth for cracks ≤2 inches) or replace if unreparable. If no cracks, reinspect every No. 1 inspection or every 115 hours until reworked by March 1, 1955, to achieve a 3/8 + 1/32 inch fillet radius.
