Plain English Summary

3/10 complexity

This AD requires owners/operators of specified Beechcraft 65-90/90 series aeroplanes (models 65-90, 65‑A90, B90, C90, C90A with S/N LJ‑1–LJ‑1222, and models E90, F90, H90) to perform the maintenance action in Beechcraft Mandatory SB 2312.

Work must be done within 100 flight hours after 9 Aug 1990 or at the next Maintenance Release inspection. It was issued because blocked drainage can let water freeze and restrict flight‑control movement; compliance costs and scheduling are the owner/operator’s responsibility.
