Full Description

This document establishes guidelines for a Reliability Assessment Plan (herein also called the Plan), in which Electronic Engine Control manufacturers document their controlled, repeatable processes for assessing reliability of their products. Each Electronic Engine Control manufacturer (the Plan owner) prepares a Plan, which is unique to the Plan owner.

This document describes processes that are intended for use in assessing the reliability of Electronic Engine Controls, or subassemblies thereof. The results of such assessments are intended for use as inputs to safety analyses, certification analyses, equipment design decisions, system architecture selection and business decisions such as warranties or maintenance cost guarantees.

This Guide may be used to prepare plans for reliability assessment of electronic engine controls in which, typically, the impact of failure is high, the operating environment can be relatively severe and the opportunity to improve the equipment after the start of production is limited. In this and similar industries, accurate estimates of expected equipment reliability are necessary prior to the start of production. This guide was produced in response to the recognized need for alternative reliability assessment and prediction methods in the wake of the decline in the availability of mil-spec parts and the declining use of military specifications and handbooks.
