Plain English Summary

3/10 complexity

This AD requires operators of specified Dassault Falcon 900/900EX and Falcon 2000 aeroplanes to carry out the work described in Dassault service bulletins to correct excess paint thickness on composite horizontal stabilisers, which can reduce lightning-spreading protection. It applies only to aircraft with particular Dassault modification numbers (with specific exclusions) and must be done within seven months of 18 April 2002. Operators bear the cost and must schedule the work; CASA enforces compliance under CAR 1998 subregulation 39.1(1).
