INSPECTIONS
5-1. GENERAL
This chapter contains the 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.
These inspection requirements constitute an approved
inspection program for the Bell Helicopter Model 212.
For the convenience of the operator, two separate
Scheduled Inspections are provided as follows:
Part A scheduled inspections consists of a daily
inspection, 100 hour/12 calendar month inspection,
1000 hour inspection, and a 3000 hour/5 year
inspection.
Part B scheduled inspections consists of a 25 hour/
30 day inspection, 300 hour inspection, 600 hour/
12 month inspection, and a 3000 hour/5 year
inspection.
Either Part A or Part B inspection program may be
utilized. However, once a helicopter has been started
on an inspection program, it shall be maintained on
that program except as follows:
• If a helicopter is being inspected on the Part A
inspection program and it is preferable to change
to the Part B program, a complete Part A — 1000
Hour Inspection shall be accomplished. The
helicopter may then be changed to the Part B
inspection program beginning with a 25 Hour/15
Day Inspection.
• If a helicopter is being inspected on the Part B
inspection program and it is preferable to change
to the Part A program, a complete Part B — 600
Hour/12 Month Inspection shall be accomplished.
The helicopter may then be changed to the Part A
inspection program beginning with a Daily
Inspection.
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 provided in this chapter are applicable only
to Bell Helicopter Textron approved parts.
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 the TBO will be introduced by either
revision to this chapter 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).
