Introduction

This Special Airworthiness Information Bulletin informs owners and operators of an airworthiness concern on aircraft equipped with BendixKing Navigator KSN 765/770 displays having part numbers 066-01204-0101, 066-01204-1101, 066-01213-0101, and 066-01213-1101 with Software Version 1.0.3, approved under Approved Model List Supplemental Type Certificate SA11174SC.

At this time, the airworthiness concern is not an unsafe condition that would warrant airworthiness directive (AD) action under Title 14 of the Code of Federal Regulations (14 CFR) part 39.

Background

During autopilot coupled instrument approaches with vertical guidance, the BendixKing KSN 765/770 may cause unanticipated pitch changes due to erroneous early glideslope/glidepath capture commands.
