Airworthiness Directives; Airbus Model A319, A320, A321, A330, and A340 Series Airplanes Equipped With AlliedSignal RIA-35B Instrument Landing System Receivers

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Airbus Model A319, A320, A321, A330, and A340 series airplanes. This action requires revising the Airplane Flight Manual (AFM) to require the flightcrew to discontinue use of any Instrument Landing System (ILS) receiver for which a certain caution message is displayed. This action also requires, for certain airplanes, replacing any faulty ILS receiver with a new, serviceable, or modified unit. This AD also provides for an optional terminating action for the AFM revisions. This amendment is prompted by a pilot's report of errors in the glide slope deviation provided by an ILS receiver. The actions specified in this AD are intended to detect and correct faulty ILS receivers and to ensure that the flightcrew is advised of the potential hazard of performing ILS approaches using a localizer deviation from a faulty ILS receiver, and advised of the procedures necessary to address that hazard. An erroneous localizer deviation could result in a landing outside the lateral boundary of the runway.

Part-conditional — 066-50006-0202.

Applies to airplanes equipped with AlliedSignal RIA-35B ILS receiver, P/N 066-50006-0202; requires AFM revision within 10 days, and replacement of the receiver within 10 days of an ILS FAULT ECAM message; affected receivers must ultimately be replaced/modified per AlliedSignal SB M-4431 (RIA-35B-34-7) Rev 1, dated May 1998.

Whether AD 98-17-05 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:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

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.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
