Plain English Summary

3/10 complexity

The directive mandates that owners/operators of BAe 125 series 800A/800B and Hawker 800 aircraft install fuselage fluid drainage Modification 253566G and perform the functional test in Hawker Mandatory Service Bulletin 53-82-3566G Rev 3 (or show an earlier compliant installation) by 31 Dec 1996. It was issued because water had frozen at an aileron pulley, risking restricted aileron control; compliance costs fall to operators.
