INSPECTIONS
5-1. GENERAL
This chapter contains the time limit interval and
requirements for the Scheduled, Special, and
Conditional Inspections and a Component Overhaul
Schedule.
FAILURE TO CORRECT CONDITIONS
SUCH AS, BUT NOT LIMITED TO,
CORROSION, EROSION, MECHANICAL
DAMAGE, OR OBVIOUS WEAR FOUND
DURING A SCHEDULED INSPECTION
COULD SERIOUSLY AFFECT THE
AIRWORTHINESS OF THE HELICOPTER.
The inspection intervals given in this chapter are the
maximum permitted. Do not exceed these intervals.
The owner/operator are responsible for increasing the
scope and frequency of the inspections as necessary.
Make sure the helicopter is operated 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.
The time period given for 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 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 Airworthiness Directives (AD).
Component operating time records are necessary for
components that have scheduled maintenance
procedures that are different from those of the
airframe. It is the owner/operator’s responsibility to
keep Historical Service Records for the applicable
components and do the necessary maintenance
procedures.
Before each inspection, remove or open the
necessary cowlings, fairings, inspection doors, and
panels.
5-2. ITEMS NOT COVERED IN THE
INSPECTIONS
This manual does not include 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 log books, and review
them for discrepancies.
2. Make sure that the Alert Service Bulletins (ASB),
the Airworthiness Directives (AD), and the special
inspections are done when they are required to be
done.
