Airworthiness Directive 2003-20-02
one-timeAirworthiness Directives; Dornier Model 328-300 Series Airplanes Equipped With Certain Pratt & Whitney PW306B Engine Nacelles
What this AD requires
This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-300 series airplanes, that requires a one-time inspection of the anti-ice tubing in the engine nacelle at the joint between the anti-ice tubing adapter and duct, and also between the joint of the anti-ice shutoff valve and the same duct, to detect any air leakage at the joints. This action is necessary to prevent an uncommanded engine shutdown in a critical phase of flight due to leakage of air from a loose clamp on the anti-ice tubing joint. This action is intended to address the identified unsafe condition.
Which aircraft AD 2003-20-02 applies to
Equipped with Pratt & Whitney PW306B engine nacelles; serial_ranges reflects engine nacelle serial number range (DR0001 through DR0051 inclusive), not airframe serial number
Whether AD 2003-20-02 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
