Alliedsignal Avionics, Inc. Appliances
Superseded. A later AD replaced this one: AD 97-05-03 R1. Comply with the one in force.
This AD applies to Alliedsignal Avionics, Inc. Global Positioning Systems.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD) that applies to all owners/operators of aircraft equipped with AlliedSignal Avionics Inc. (AlliedSignal) Models GNS-XLS or GNS-XL global positioning systems (GPS) Flight Management Systems. This action requires inserting a limitation into the Airplane Flight Manual (AFM) or Flight Manual Supplement Limitations Section prohibiting the use of these AlliedSignal GPS units on previously published non-precision approaches. This action is prompted by recent reports of flight course deviations because of erroneous information provided by the GPS Flight Management System. The actions specified by this AD are intended to prevent deviation from an intended flight path during a non-precision approach to an airport.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
