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.
