In a manner similar to
Airworthiness Directives and Service Bulletins that are
issued for aircraft certificated in other categories, Flight
Design issues Safety Directives (also known as Notices).
These are notifications of corrective actions determined by
Flight Design in response to a reported safety of flight or
service difficulty issue.
The content and format is determined by applicable Federal
Aviation Regulations as well as ASTM standards for "Notice
of Corrective Action" and "Operational Risk Assessment
Procedure".
There are three types of Safety Directive:
"Notification" for notifications that do not necessarily
recommend future action but are primarily for promulgation
of continued airworthiness information.
"Service Bulletin" for notifications that do not require
immediate action but do recommend future action.
"Safety Alert" for notifications that require immediate
action.
Note: Flight Design does not use notices of corrective
action (Safety Directives) to promote or make mandatory
non-safety of flight related equipment upgrades or
additions.
