Plain English Summary

3/10 complexity

This directive requires owners/operators of Colonial C1/C2 and Lake LA‑4/LA‑4‑200 aeroplanes with 2‑7811‑7 pushrod assemblies (unless fitted with Heim HM‑5G Magnafluxed rod ends) to carry out inspections — and replace bearings when indicated — following Consolidated Aeronautics SL No. 39A. The first inspection is due within 15 hours TIS after 5 Jan 1973 (unless recently done), then every 25 hours TIS. Costs and downtime fall to operators, creating an incentive to retrofit the exempt rod ends.
