Abstract
We are adopting a new airworthiness directive (AD) for Northrop Grumman LITEF GmbH LCR-100 Attitude and Heading Reference System (AHRS) units installed on various aircraft. This AD requires removing certain LCR-100 AHRS units from service. This AD was prompted by test results showing loss of or invalid data. The actions of this AD are intended to prevent an unsafe condition on these products.
