The Piaggio P.136 was a twin-engine pusher-type amphibian, being capable of carrying a maximum of five people with baggage, or a pair of stretchers and an accompanying medical attendant. While the general configuration and systems remained largely the same across different models, there were some customisations present in the cabin to suit its customer and intended purpose; while military aircraft would often be fitted with alternative instrumentation and radio sets, as well as additional transparent panels in locations like the doors for greater external visibility, civil P.136s would be furnished with more comfortable seating and additional panelling for sound exclusion and heat retention purposes. The aircraft's fuel is stowed in two large metal tanks housed within the hull. More than 80 P.136 five-seat light amphibians were built as one of the company's first post-war products, 23 of which were supplied to the Italian Air Force for use as flying-boat trainers and for air-sea rescue duties. Trecker Aircraft Corp, a division of Kearney & Trecker Corporation, in early/mid-1960s assembled at Milwaukee, Wisconsin, Piaggio P.136L-1 s and L-2s under names Trecker Gull and Super Gull.
