General The BK117 D-2 is a
multi purpose twin engine
helicopter in the 4 t class with
eight seats in the basic version

4. Main Rotor System
The main rotor
blades are
manufactured from

6. Maintenance Concept
GENERAL
Maintenance” covers all scheduled and
unscheduled maintenance activities. It also
applies to the on condition maintenance. It is
based on condition monitoring by visual
checks/inspections and diagnostic features such
as chip detectors, filter bypass indicators,
boroscope access, failure code indications,
built-in tests, warning lights etc.
ORGANIZATIONAL
LEVEL
DEPOT LEVEL (D)
INTERMEDIAT
E LEVEL
The organizational level covers tasks of
the daily servicing,
maintenance checks, inspections for
condition, exchange of
components (e.g. LRU) and quick, simple
repairs as specified in the
aircraft maintenance manual (AMM)
The intermediate level covers repairs on/off
helicopter, extended
periodical inspections as specified in the
aircraft maintenance manual.
To fulfill these tasks, maintenance facility,
qualified personal, test
equipment and special tools are required.
Depot level covers major repair or
overhaul at the manufacturer or at
authorized service stations under
industrial premises.
More extensive tools/test equipment and
specialized personnel are
necessary.
 NOTE The maintenance manual covers
all tasks of organizational level and intermediate
level.
NOTE Documentation and spares for depot
level tasks will be delivered to authorized customers only.
