2. Description
A. Pitot Head/Lines
The Pitot head of the DV 20 KATANA is designed to measure total head and static pressure. The
Pitot head is located below the left wing. Lines running through the left wing and the fuselage
connect the Pitot head to the instruments. The lines for total head are green, and the lines for static
pressure are blue.
The lines are attached to the connectors and secured with tie wraps.
B. Drain System
A drain system allows dewatering of the pressure lines.
If Service Bulletin No. 20-6 has not been carried out, this drain system consists of moisture filters
located in the wing root area. The moisture filters are accessible after removing the left wing.
If Service Bulletin No. 20-6 has been carried out, each pressure line has a bypass hose forming
a water sump. The pressure lines can be dewatered after removing the left seat shell.
From Serial No. 20.046 on, all DV 20 KATANA's are factory-equipped with the water sump type
drain system.
