Plain English Summary

2/10 complexity

This AD requires Twin Commander 690/690A owners to add bonding points at every fuel fill and external earthing points on the landing gear so static charge from refueling is safely conducted away.

It affects operators of those models and matters because proper bonding/grounding prevents sparks that could ignite fuel vapors; compliance was required by 31 March 1975.
