Alpine Aviation
Grass Valley, California, United States
Alpine appears to be a legitimate active aircraft dealer/sales representative rather than a pure aircraft brokerage firm. Its strongest public support is official and regulatory: FAA dealer registration, Diamond sales representation, Part 135 charter status, FAA repair-station claims, and current marketplace/directory presence. The official website emphasizes charter, training, maintenance, management, avionics, and pre-buy work more heavily than aircraft sales, so the sales-brokerage scope should be manually reviewed before presenting it as a full acquisition or resale brokerage.

Public discussion is mostly about Alpine Aviation's flight training, maintenance, avionics, seaplane instruction, and charter work rather than aircraft sales. The visible signal is mixed-positive overall: reviewers and forum participants often praise technical knowledge, Diamond/Cirrus familiarity, seaplane instruction, fairness, and repair execution, while a smaller number of review snippets criticize professionalism or inquiry handling. Sales-specific reputation evidence is thin, so public confidence in broker/dealer execution should be treated as limited.
Positive themes
- Knowledgeable staff and instructors
- Positive seaplane training experiences
- Diamond aircraft maintenance familiarity
- Avionics and repair competence

Negative themes
