8.1 Introduction
This section contains manufacturer's recommended procedures for proper
ground handling and servicing of the sailplane. It also identifies certain
inspection and maintenance requirements which must be followed if the
sailplane is to retain that new-plane performance and dependability. It is
wise to follow a planned schedule of lubrication and preventive
maintenance based on climatic and flying conditions encountered.
8.2 Inspection period, maintenance
The "Instructions for continued airworthiness (maintenance manual) for the
DG-500 ELAN ORION have to be followed.
A Before each rigging all the connecting pins and bushes should be cleaned
and greased. This includes the control connectors.
B The contact surfaces of the canopies to the fuselage are to be rubbed with
colourless floor-polish (canopy and fuselage side) to reduce grating noise
in flight. Polish at the beginning of the flight season and then every month.
C Once a year all the bearings and hinges should be cleaned and greased. See
the greasing programme of the maintenance manual.
Each year the control surface displacements, adjustments and general
condition must be checked. (See the maintenance manual).
8.3 Alterations or repairs
It is essential that the responsible airworthiness authority be contacted
prior to any alterations on the airplane, to ensure that the airworthiness of
the sailplane is not impaired. It is prohibited to execute the alteration
without the approval of the airworthiness authority. The manufacturer will
not be liable for the alteration or for damages resulting from changes in the
characteristics of the aircraft due to alteration. So it is strongly
recommended to execute no alternatives which are not approved by the
aircraft manufacturer.
External loads such as external camera installations are to be regarded as
alterations! Repair instructions can be found in the DG-500 ELAN ORION
repair manual. No repairs should be carried out without referring to the
manual.
