Plain English Summary

3/10 complexity

This Airworthiness Directive mandates a modification to the fuel pump drive coupling on specified Pratt & Whitney Canada PT6A/PT6B engines (only certain serial numbers) to improve lubrication. It affects owners and operators of those engines, who must comply with one of three approved technical documents (UACL Service Bulletin No. 230 Rev 3, No. 1165, or AD/UAC‑T/11A) within the prescribed timelines. The change prevents premature coupling wear or failure that could cause engine malfunction or in‑flight shutdown.
