AIRWORTHINESS OF THE HELICOPTER.
The inspection intervals given in this chapter are the
maximum permitted. Do not exceed these intervals.
The owner/operator is responsible for increasing the
scope and the frequency of the inspections as
necessary. Make sure the helicopter is maintained
safely during all unusual local changes, such as
environmental conditions, helicopter use, etc. You can
request changes to the requirements in this chapter
through the local aviation authority.
The inspection intervals and the Component Overhaul
Schedule given in this chapter are applicable only to
Bell Helicopter Textron approved parts.
NOTE
The time period given for the overhaul of a
component (or the failure to give a time
period for the overhaul of a component)
does not constitute a warranty of any kind.
The only warranty applicable to the
helicopter or any component is the
warranty included in the Purchase
Agreement for the helicopter or the
component.
The Time Between Overhaul (TBO) and the inspection
periods are determined through experience, tests,
Lead-The-Fleet (LTF), or any other special programs
and the judgement of Bell Helicopter Textron
engineers. They are subject to change only by Bell
Helicopter Textron or an approved airworthiness
authority.
Changes to TBO will be introduced by either revision
to the Maintenance Manual Chapter 5 or a Technical
Bulletin.
Every calendar and hourly inspection is a thorough
visual inspection to determine the airworthiness of the
helicopter and the components. Qualified persons
must do the inspections in accordance with quality
standard aircraft practices and the applicable
maintenance manuals. Bell Helicopter Textron
considers that it is mandatory to obey all the
applicable Alert Service Bulletins (ASB) and the
Airworthiness Directives (AD).
Component operating time records are necessary for
components that have scheduled maintenance
procedures which are different from those of the
airframe. It is the owner/operator’s responsibility to
keep the Historical Service Records for the applicable
component and to do the necessary maintenance
procedures.
Before each inspection, remove or open the
necessary cowlings, fairing, inspection doors, and
panels.
5-2. ITEMS NOT COVERED IN THE
INSPECTION
This manual does not include the specific inspection
intervals for some components such as the compass
calibration and the pitot static test. These specific
inspection intervals are given by your government
regulatory authority. Refer to their requirements for
these specific inspections.
The owner/operator of the helicopter is responsible for
the maintenance done on the helicopter. It is the
owner/operator’s responsibility to:
1. Establish and maintain the log books, and review
them for discrepancies.
2. Make sure the Alert Service Bulletins (ASB), the
Airworthiness Directives (AD), and the special
inspections are done when they are required to be
done.
