Plain English Summary

4/10 complexity

This Airworthiness Directive obliges operators of specified Beechcraft 65‑90 and B90 (King Air) aeroplanes to perform initial and recurring inspections of the elevator spar web and hinge points. It applies to serial numbers LJ‑1 through LJ‑501 except aircraft fitted with certain reinforced elevators or specified kits, and refers to Beechcraft Service Instructions.

The inspection timing depends on model and fitted equipment: operators must meet the stated initial flight‑hour thresholds and then carry out repeating inspections at the prescribed hour intervals. Operators pay inspection costs and must schedule maintenance to comply.
