EASA SIB CE-19-14: Rockwell Collins Pro Line Fusion Flight Management Systems

What to do

Operators should avoid using the DELETE function to remove waypoints in the affected Rockwell Collins Pro Line Fusion FMS models. Instead, they should follow alternative waypoint removal methods as detailed in Rockwell Collins Operators Bulletin OPSB 0194-19. Any occurrences of this issue should be reported directly to the FAA contact provided in the bulletin. No specific compliance deadline is stated.

Summary

The Special Airworthiness Information Bulletin SAIB: CE-19-14 is an FAA informational bulletin regarding the Rockwell Collins Pro Line Fusion Flight Management Systems with part numbers 810-0163-2B0004, 810-0163-3B0001, and 810-0163-1F0001. It addresses a software issue where deleting a waypoint may cause the system to fly an incorrect turn direction during departures, STARs, or approaches. This bulletin does not impose mandatory actions but informs operators of the potential navigation anomaly.

What changed

This bulletin introduces awareness of a flight management system software issue that can cause the Pro Line Fusion FMS to execute an incorrect turn direction when a waypoint is deleted under certain conditions. It clarifies that this issue does not currently warrant an airworthiness directive under 14 CFR part 39. The FAA recommends avoiding the use of the DELETE function to remove waypoints and refers operators to Rockwell Collins Operators Bulletin OPSB 0194-19 for alternative procedures.

Why it matters

This issue matters because incorrect turn directions during critical flight phases such as departures, STARs, and approaches can affect flight safety and operational efficiency. Operators and maintenance teams need to be aware of this anomaly to prevent unintended flight path deviations. Understanding this helps compliance teams manage risk and maintain safe navigation practices without mandatory regulatory action.
