Plain English Summary

2/10 complexity

This AD mandates owners/operators of Beechcraft King Air E90 aeroplanes in Australia to carry out three hardware modifications—bonding points at fuel filler caps, external earthing points on landing gear, and a power-advisory light for the turn coordinator—by 29 August 1975.

The changes prevent static discharge during refuelling (reducing fire/explosion risk) and ensure pilots are warned if the turn/slip instrument lacks electrical power.
