SECTION 17.
SAILPLANE REPAIRS
17.1. Introductory remarks
This manual provides guidance for composite sailplane minor damages
repairing by organizations approved acc. to Part 145 or Part M/F (or equivalent
outside the EASA), which demonstrated ability to perform composite structures
repairs (damages are classified in item 17.2.2.) and metal processing (17.6.3.).
The second group of damages, more serious than specified in item 17.2.2. but
not requiring factory repair yet, will be investigated individually by Type Certificate
Holder having regard to the factual condition and qualified to the appropriate
category of damage repairs
– minor or major. Depending on the classification of
repair it can be done by mechanic with licence for composite structures repair or
certified service workshop, approved for the composite structures repair, based on
approved repair procedure.
Damages, which the possibility of repair by the abovementioned organizations
themselves are excluded, are given in item 17.2.2.
Complete and familiarize with the following documents before proceeding to
repair:
aircraft log book,
Technical Service Manual,
service history, maintenance status, parts and components with a limited lifetime
status,
airworthiness directives and bulletins status,
previous repairs certificates,
review and inspection records.
If relevant regulations or repair contractor status require, starting repair should
be reported to state aviation authority appropriate
for user’s location.
After repair a new mass (m
p
) and centre of gravity position (X
p
) for
“empty”
sailplane with minimal equipment should be determined by weighing according to
item 8.1. For sailplane with additional equipment mounted and possible fixed ballast
specify new mass „without pilots” (m
bp
) and corresponding CG position (X
bp
) and
prepare a new table „Individual loading plan” in accordance with item 6.5. in Flight
Manual.
