Plain English Summary

2/10 complexity

This directive requires all Douglas DC‑3 series aeroplanes to have a hydraulic modification installed per Douglas Service Bulletin No. 239, completed within 100 hours TIS after 31 May 1984 (unless already done). CASA reissued the AD unchanged. Owners/operators must fund and schedule the work; the safety aim is to preserve hydraulic pressure to raise the undercarriage if an engine fails during take‑off.
