This airworthiness directive makes the technical instructions in Allison CEB‑51 and CEB‑52 mandatory for all Allison 250‑C18 engines, requiring the specified compressor modifications to be carried out by 25 October 1968.

It affects owners, operators and maintenance organisations responsible for those engines: the AD converts manufacturer guidance into a compulsory regulatory obligation, with compliance costs, scheduling and technical detail borne by the responsible parties.
