B Inspection after rigging
Walk around the aircraft
1. All parts of the airframe
a) check for flaws such as bubbles, holes, bumps and cracks in the surface
b) check leading and trailing edges of the wings and control surfaces for
cracks
2. Cockpit area
a) check the canopy locking mechanism
b) check the canopy emergency release see sect. 7.15 (not each day, but
min. every 3 month)
c) check the main pin securing
check the securing ropes of the headrest in the rear cockpit for wear and
function
d) check all controls for wear and function, incl. positive control check
e) check the tow release system for wear and function incl. cable release
check
f) check for foreign objects
g) check the instrumentation and radio for wear and function
h) check the radio and other electrical equipment for function. If there is no
electric power it must be assumed, that the battery is not in-stalled in the
fin. Flying is only allowed with the battery in the fin as otherwise the
forward C.G. limit may be exceeded.
i) check the brake fluid level
j) check if the fin tank is empty
3. C.G. Tow hook
a) c heck the ring muzzle of the C.G. hook for wear and function
b) check for cleanliness and corrosion
4. Main landing gear and nose wheel
a) check the struts, the gear box, the gear doors and the tyre for wear; dirt in
the struts can hinder the landing gear from locking over center the next
time!

Flight manual DG-500 ELAN ORION
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.
