Alterations or repairs
Alterations
Alterations on the approved model, which might affect its airworthiness, must be
reported to the responsible airworthiness authorities p r i o r to their
accomplishment.
The authorities will then determine whether and to what extent a “supplemental
type approval” is to be conducted.
In any case, the manufacturer’s opinion about the alteration(s) must be obtained.
This ensures that the airworthiness does not become adversely affected
and enables the aircraft owner/ operator to demonstrate at any time that the
powered sailplane concerned complies with an LBA-approved version.
Amendments of the LBA-approved sections of the Flight- and/or Maintenance
Manual must in any case be approved by the Luftfahrt Bundesamt (LBA).
Repairs
Abbreviations:
CFRP: carbon-fibre reinforced plastic
GFRP: glass-fibre reinforced plastic
Before every take-off and especially after the powered sailplane has not been
used for a while, it should be checked on the ground as shown in section 4.3.
Check for any sign of a change in the condition of the aircraft, such as cracks in
the surface, holes, or delamination in the CFRP/GFRP structure etc.
If there is any uncertainty whatsoever regarding the significance of damage
discovered, the Arcus M should always be inspected by a CFRP/GFRP expert.
There is no objection to minor damage - which does not affect the airworthiness in
any way - being repaired on site.
A definition of such damage is included in the “REPAIR INSTRUCTIONS" which
are found in the appendix to the Arcus M Maintenance Manual.
Major repairs may only be conducted by a certified repair station having
appropriate authorization.
