1811 SERIES
PITOT-STATIC TEST SET
INFORMATIONAL LETTER
The
Barfield 1811 series Pitot-Static Testers
are not advertised for use to comply with
FAR 91.411. The Test Sets do fully meet the requirements of DOT Advisory Circular 43-203B
for performing Altimeter and Static System Tests and Inspections. However, the personnel
requirements and some of the technical aspects of actual testing put a sizeable burden on the
person or persons performing the test.
Barfield
advertises its 1811 series Test Sets as general-purpose trouble-shooting testers. With
respect to compliance with FAR 91.411, we feel that the customer should first be aware of
all
requirements for performing test tests in the field. With this in mind, Barfield stands ready to
offer advice and assistance to its customers for accomplishing the required tests.
In conclusion, the Barfield 1811 Series Pitot-Static Testers meet the requirements for
compliance with FAR 91.411, but it is important that the customer be sure that the use of the
test set will be in compliance with the regulations.
Please note that a
Barfield Altimeter and Static Test Procedure
(Document number 60-101-
00150) is available to use in compliance with FAR 91.411.
