Airworthiness Directive · Amendment 39-21501 · Navigation system
Rockwell Collins, Inc., Global Positioning Systems
This AD applies to Rockwell Collins, Inc. GPS-4000S Global Positioning System (GPS) part number (P/N) 822-2189-100 installed on airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Rockwell Collins, Inc. (Rockwell Collins), GPS-4000S Global Positioning Systems (GPS) installed on airplanes. This AD was prompted by an un-annunciated GPS position error, which could cause a misleading localizer performance with vertical guidance (LPV) glidepath, resulting in controlled flight into terrain (CFIT). This AD requires upgrading the GPS-4000S. The FAA is issuing this AD to address the unsafe condition on these products.
(1) Within 24 months replace each GPS-4000S GPS P/N 822-2189-100 with a GPS that does not have P/N 822-2189-100.
(2) As of 24 months after the effective date of this AD, do not install GPS-4000S GPS P/N 822-2189-100 on any airplane.
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.
