Advisory U.S. Department of Transportation Circular Federal Aviation Administration Subject: Seaplane Bases Date: 8/31/2018 AC No.: 150/5395-1B Initiated by: AAS-100 Change: 1 Purpose. This advisory circular (AC) provides guidance to assist operators in planning, designing, and constructing seaplane bases and associated facilities. 2 Cancellation. This AC cancels AC 150/5395-1A, Seaplane Bases, dated August 6, 2013. 3 Application. The FAA recommends the standards and recommendations in this AC for use in the design of civil seaplane bases. In general, use of this AC is not mandatory. Use of this AC is mandatory for all projects funded with federal grant monies through the Airport Improvement Program (AIP) and/or with revenue from the Passenger Facility Charges (PFC) Program. See Grant Assurance No. 34, Policies, Standards, and Specifications, and PFC Assurance No. 9, Standards and Specifications. 4 Principal Changes. This revision includes the following changes: 1. Updated definitions and guidance for filing notices to the FAA in Chapter 1. 2. Restructured Chapter 2 for clarity. 3. Clarified the basic components of a public-use seaplane base as suitable water operating area, which in turn, consists of approach/departure paths and designated sea lane(s). Components may include taxi channel(s), an anchorage area, and a shoreline ramp or pier (Chapter 1). Depending on user needs, shoreline or on-shore facilities may become basic components (Chapter 4 and Chapter 5). 4. Simplified the discussion on piers, fixed dock, and floating docks into a comprehensive section discussing docks (paragraph 4.4). 8/31/2018 AC 150/5395-1B 5. Deleted Table 2-1, Recommended Sea Lane Dimensions, Water Depths, Approach Slopes in Feet (Meters), and incorporated design information into Chapter 3 for seaplanes currently operating in the system. 6. Updated the format of the document, and made minor editorial changes throughout.
