Continued Airworthiness
3.0 Inspection/Test
Requirements
3.1 General
Information
This section covers the basic maintenance and service requirements necessary for
safe operation and continued airworthiness of the Model 1500EFS Engine Inlet Barrier
Filter System.
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 inlet filter, an important criterion for safe
operation is an unobstructed inlet/filter. This can be accomplished by visual inspection
of the filter through the inlet fairing prior to each flight. Small suspended particles on
the outside of the filter element do not cause an appreciable airflow restriction.
However, 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 and 4.4 for post cleaning inspections.
