Technical Data
No Hot Section Inspection (HSI) is scheduled and, if necessary, component replacement will be on an
on-condition basis.
The maintenance plan for the PW206B2 engine incorporates the following features:
The minimization of scheduled maintenance in accordance with MSG-III style analysis.
Helicopter Engine Condition and Trend Monitoring (HECTM®) used to determine the economical
threshold to perform refurbishment.
Repair development will continue during service of the PW200 engine with the objective of expanding
on repair schemes currently contained in both the Maintenance Manual and Overhaul Manual. This will
keep engine maintenance costs, aircraft downtime, spare engine inventories and total operating costs
to a minimum.
Accessories Time Between Overhaul
Engine accessories are monitored, as defined by the Illustrated Parts Catalog, with a removal threshold
that is based on the operator's experience, with the following exception: TBO recommendation for the
Fuel Management Module (FMM) is engine TBO plus 500 hours.
Periodic Inspection - Tolerances
Unless otherwise stated, the tolerance for periodic or scheduled inspections are as follows:
• Hourly Interval tolerance: Ten percent (10%), or up to a maximum of 100 hours operating time,
whichever is less.
• Calendar Interval tolerance: Ten percent (10%), or up to a maximum of 30 days calendar time,
whichever is less.
NOTE:The tolerance is established for maintenance scheduling convenience only and must be approved
by the governing civil aviation authority. Subsequent intervals will be adjusted to re-establish the
original schedule. When an inspection is done more than 10% early, subsequent inspections will be
advanced as required so as to not exceed the maximum tolerance. Concurrence and final approval of
the inspection interval tolerance by the governing civil aviation authority is the responsibility of the owner/operator.
