SECTION 3
Inspection/Test Requirements
3.1 General
This section covers the basic maintenance and service requirements necessary for safe
operation and continued airworthiness of the Model 1206 and 1407 Engine Filter Systems.
The service and inspection intervals designated herein are the maximum allowable and
should not be exceeded.
3.2 Service Intervals
When severe or unusual environmental conditions exist or as flight requirements
dictate, it is the responsibility of the operator to increase the frequency and scope of
inspections necessary to ensure safe operation. Due to the operational nature of a
"barrier" type filter, an important criteria for safe and successful operation is an unobstructed
inlet/filter system. This can be accomplished by visual inspection of the filter through the
inlet fairing prior to each flight. Where as small suspended particles on the outside of the
filter element do not cause an appreciable airflow restriction, large, obvious debris such as
leaves, brush, litter, etc., should be removed prior to flight. Good judgment and practice will
ensure safe operation as well as long filter life.
Inspections, scheduled and conditional, shall be performed by qualified personnel and in
accordance with standard aircraft practice. Compliance with all applicable Service Bulletins
and Airworthiness Directives is mandatory.
Refer to paragraphs 4.3.1 and 4.3.2 for post cleaning inspections.
