The S-38 was a nine-seat commercial amphibian powered by two 313kW Pratt & Whitney Wasp radial engines. A sesquiplane wing arrangement was employed and the tail unit was carried on two outriggers running aft from the main wing and braced to the heel of the hull by two struts. It was a successful design and many were built for airline use (including Pan American Airways, entering service in October 1938), private use and for the US Navy/USAAC. The type also set several world records for speed and altitude with specific loads.

| Jerry Noosinow (PAA Ret), noosinow(@)charter.net, 13.09.2008 Is there any info on how many S-38's were built and who besides PAA and the U.S. Navy operated them? | | Roger Derby, derbyrm(@)insightbb.com, 22.05.2008 During the take-off run on water, the passenger in the right front seat would get wet with spray from the wheel well.
Entry to the passenger compartment was through a hatch in the top of the hull, reached by a ladder.
The pilot and mechanic compartment was open so they could hear the wind in the rigging. |
