Important Engineering Terminology Differences (from April 2003 Beartracks)
"In order to standardize the use of the words below, it is necessary to define what each term means when it is published in the newsletter. Here is how we use the terms:
ENGINEERING CHANGE NOTICE: Design change that requires immediate attention to affected serial numbers. This NOTICE contains the technical information to correct the unsafe condition.
ENGINEERING CHANGE: A change to current serial number drawings onward - non-mandatory - may or may not be published. This change is the result of a product improvement, update or modification. Or a minor change of the design to ease manufacturing, maximize utility, economize materials or ease assembly.
ENGINEERING REPORT: Field or lab test data that is disseminated to the builder in the form of a report. An Engineering Report may generate an Engineering Change Notice or an Engineering Change or neither. The report may or may not validate the design. A summary of the results will always be attached with our thoughts and recommendations."
Please note that once a notice or update is released, all plans numbers from that time forward have already been changed to reflect the updates/notices. Therefore, if your plans are dated after the dates listed below, there is no need to do anything. Your plans should already reflect the changes.
