Plain English Summary

3/10 complexity

Mechanically, the directive requires Dornier 328-100 operators to insert Dornier All Operators Telefax No.AOT-328-00-022 Revision 1 (or a later LBA‑approved revision) into the Aeroplane Flight Manual and to advise flight crew to operate accordingly before the next flight. It took effect 28 November 2005 after tests showed undiluted Type II/IV propylene‑glycol de/anti-icing fluids can remain on wing and control surfaces during takeoff, temporarily reducing lift, increasing drag and impairing controllability. Operators pay to update manuals and brief crews; the CASA delegate issued the AD.

Dornier 328 Series Aeroplanes

AD/DO 328/4	De-icing/Anti-icing Fluids	1/2006 TX

Applicability:	Dornier 328-100 series aeroplanes.
Requirement:	Unless previously accomplished insert Dornier 328 All Operators Telefax No.AOT-328-00-022 Revision 1 dated 7 November 2003 or later LBA approved revision into the Aeroplane Flight Manual and advise the Flight Crew to operate the aeroplane accordingly until further notice.Note: LBA AD D-2004-007 EASA Approval No. 2004-48 dated 8 January 2004 refers.
Compliance:	Before further flight.
	This Airworthiness Directive becomes effective on 28 November 2005.
Background:	Testing of undiluted de/anti-icing fluids (Type II and IV fluids, based on propylene glycol) has shown that some of the fluid remains on wing, aileron and flap surfaces during the takeoff run, rotation and during initial climb out. This causes a temporary decrease in lift, increase in drag and can lead to reduced controllability of the aeroplane.
