Plain English Summary

2/10 complexity

This Airworthiness Directive orders operators of Dornier 328‑100 aeroplanes (serial numbers 3005–3093) fitted with jet booster pump P/N 219335‑2 to replace them with improved P/N 219335‑3 pumps within 30 days, using Dornier Service Bulletin No. 328‑28‑211. The change addresses a valve failure that can cause low fuel pressure and trigger a “FUEL PRESS LOW” alert during critical flight phases. Operators must fund and schedule the replacement quickly to keep affected aircraft airworthy.

	This Airworthiness Directive becomes effective on 19 January 2006.
Background:	A failure of the jet booster pump non-return flap valve would lead to a fuel pressure lower than needed to feed the engine without usage of the electrical fuel pump. To avoid CAS message “FUEL PRESS LOW” and respective corrective action by the crew especially during takeoff and landing requires modified jet booster pump to be installed.
