Where PE licensure applies (and where the industrial exemption applies instead), the FAA Type Certificate and Supplemental Type Certificate processes, the safety-critical culture behind redundancy and extensive testing, and the professional ethics of never signing off on airworthiness without genuine verification.
Most aerospace engineers never seal a drawing the way a structural PE does — the industry's primary accountability mechanism runs through FAA certification instead. This module works through what a Type Certificate and a Supplemental Type Certificate actually represent, why aerospace's safety-critical culture builds redundancy in proportion to a failure's consequence rather than uniformly, and why extensive testing and the documentation trail behind it exist to prove a compliance finding was genuinely earned rather than assumed.
By the end of this module you should be able to explain why an STC can require compliance analysis beyond its own modification's scope, and why the real ethical risk in this field is rarely dramatic falsification — it is the quieter, far more common failure of letting "probably fine" substitute for "actually checked" on a routine finding under ordinary schedule pressure.
