Plain English Summary

5/10 complexity

This directive requires all Douglas DC‑4 models to undergo a radiographic inspection for cracking of lower mainplane stringers 18–21 between the front and centre lower spars (wing stations 167–281). It affects DC‑4 owners/operators and maintenance providers; inspection costs fall to operators, and the Secretary determines which radiographic technique is acceptable. Timing, intervals and corrective actions are unspecified, so operators must obtain regulator guidance to implement compliance.
