Plain English Summary

3/10 complexity

This directive requires operators of Dornier 328‑100 aeroplanes to perform recurring inspections and an operational check of the engine air‑intake de‑icing boots, using Dornier Service Bulletin SB‑328‑30‑432 (or later LBA‑approved revisions). Inspections must be done at intervals not exceeding 60 flight hours (inspection) and 800 flight hours (inspection plus operational check); operators bear the inspection and scheduling costs because the action addresses reported debonding/delamination that can restrict intake flow and risk engine failure.

Dornier 328 Series Aeroplanes

AD/DO 328/14	Engine Air Intake De Icing System	1/2006

Applicability:	Dornier 328-100 aeroplanes.
Requirement:	1. Carry out an inspection of the engine air intake de-icing boots in accordance with paragraph 2.B.1 of Dornier 328 Service Bulletin No. SB-328-30-432 dated26 April 2002 or later LBA approved revisions.2. Carry out an inspection and operational check of the engine air intake de-icing boots in accordance with paragraph 2.B.2 of Dornier 328 Service Bulletin No. SB-328-30-432 dated 26 April 2002 or later LBA approved revisions.Note: LBA AD 2002-256 refers.
Compliance:	1. At intervals not to exceed 60 flight hours.2. At intervals not to exceed 800 flight hours.
	This Airworthiness Directive becomes effective on 19 January 2006.
Background:	The engine air intake de-icing system eliminates any ice formation on the leading edges of the engine air intakes. There have been several problems with debonded or delaminated de-icing boots. The consequence following a debonding or delamination of the engine-inlet de-icing boot could be an engine failure due to severe intake flow restriction.
