Attachment 4 - Spray Boom Diagram.pdf

This document is an attachment containing a technical diagram of an aircraft spray boom system. The diagram illustrates the configuration of a spray boom apparatus designed for the AIRCRAFT SPRAY SYSTEM MODIFICATION, with two detailed views showing the boom's positioning and components relative to the aircraft fuselage and wings.

The diagram depicts both the right wing and left wing installations, each indicating that the boom extends approximately three-quarters of the wingspan. Key features shown include the boom's connection points to the aircraft structure, the spatial relationship between the boom and the aircraft body (marked with red and green circles indicating reference points), and the shelter or housing units (marked with numbered boxes) associated with the spray system. The technical illustration demonstrates the mounting configuration and spatial requirements necessary for the spray boom installation on the aircraft, with particular attention to clearances and positioning relative to the fuselage and wing surfaces. This diagram serves as a reference specification for contractors involved in the design or implementation of this aircraft spray system modification project.
