Exec 162F Maintenance Manual

INTRODUCTION
In this Maintenance Manual, the components of the helicopter have been divided into 20 sections. Each of these sections
begins with a brief description of the component, followed by an “Inspection Chart”. This chart shows the Inspection
Interval, Recommended Change Out time (R.C.O.), and a Service Reference for each part. The Service Reference
directs the builder to the procedure to be followed for each inspection. In most cases, a Service Note (found on the
following page), a footnote, or a Construction Manual section will be referenced.
Many parts listed are given a specific lifetime to be replaced as specified in the Inspection Charts. In order to extend the
lifetime, these parts could require extensive inspection. Visual inspection of certain items may show the part to be serviceable,
but they may have a fatigue life that requires their replacement. This policy provides each part with a safety factor to
enable its replacement before failure.
The R.C.O. time represents the lifetime of a component as recommended by the manufacturer. A phrase called “on
condition” or O.C. is also utilized in this manual. This means the part should be monitored and replaced if suspect prior to
the R.C.O. time of the component. Common examples of parts that qualify for O.C. replacement are bearings and belts.
When these parts are not correctly installed or not cleaned properly, they may fail prematurely.
Even though close quality control procedures are adhered to, a part may fail prematurely due to a variety of reasons.
Incorrect manufacturing procedures, builder errors, environmental conditions and storage conditions may all contribute.
Because premature failures can happen, it is important to monitor all major components during pre- and post-flight
inspections.
Clearances and tolerances for proper inspection will be noted in the section, if applicable, for part replacement. Other data
such as crankshaft tolerances, rod clearance and cam dwell, etc., is proprietary information. If the need arises for the
builder to have this information, a technical representative from the factory should be contacted.
