FAA MOSAIC

The FAA’s MOSAIC rule (finalized July 2025) enables experimental amateur-built owners to perform their own annual inspections after a short course, legitimizing undocumented “gray” maintenance—especially common in Alaska—and significantly improving documentation, financing, and value for well-maintained aircraft, particularly bush planes like Super Cub and PA-12 clones.This creates a sharp value divergence: high-quality, properly documented E-ABs gain substantially (amplified in Alaska’s premium market), while marginal or poorly documented ones may stagnate or decline, with long-term effects depending on self-maintenance’s impact on safety.
