Certification Lifecycle Infrastructure for STC Holders
AvioDesign structures approval management, documentation integrity, DER coordination and post-approval operational oversight for active and legacy STC portfolios.
Many STC programs lose structure after approval.
Obtaining FAA approval is only part of the certification lifecycle.
Over time, many STC programs experience:
Fragmented documentation
Incomplete approval records
Inconsistent revision control
Unsupported field installations
Loss of technical continuity
Unresolved deviations
Approval knowledge concentrated in one individual
Aging DER relationships
Uncertainty surrounding continued support responsibilities
As portfolios grow, maintaining certification continuity becomes operationally critical.
