10. Repairs
10.1
General.
Repairs should either be carried out as described below, or to a
scheme approved by the BMAA. After repairs, you should always obtain a
"second inspection" from a qualified pilot or (preferably) BMAA inspector after
making any repair, who should sign in the logbook that they have inspected
the repair and consider it safe. Where this is not possible, draw the repair to
the attention of your inspector at the next permit renewal who should
oversign your own entry.
10.2
Sail Repairs.
Sail (flexible surface) repairs must be carried out in
accordance with BMAA Technical Information Leaflet TIL 015.
10.3
Repairs to tubular structure, springs, pulleys, cables, bolts, nuts, etc.
Any such damaged parts must not be repaired and the aircraft must not be
flown once the damage has been identified. Identical replacement parts must
be fitted before any further flight, and their installation inspected and signed-
off in the logbook by a BMAA inspector. The invoice (legally referred to as the
certificate of conformity) for the parts fitted must kept with the aircraft
logbook. If it is not possible to obtain replacement parts, consult the BMAA
Technical Office for advice.
10.4
Repairs to the Engine.
These should be carried out in accordance with the
maintenance manual for the engine fitted.
10.5
Repairs to Instruments.
Microlight aircraft instruments are not usually
repairable and should be replaced.
10.6
Repairs to Fuel Hose.
Any fuel hose which is found to be cracked or
damaged must not be repaired. Replace it with at least automotive quality
(preferably aircraft or fire-retardant boat use) reinforced rubber fuel hose. It
is not advised that transparent fuel hose is used, and PVC hose must not be
used with fuel under any circumstances. Take care not to over-tighten cable
ties used to secure hose, since this can cause a flow restriction.
10.7
Damaged Wiring.
Replace with fireproof or fire resistant wiring of the
same or higher current rating, secured in the original manner.
10.8
Repairs to Batteries.
A damaged battery must be replaced and all
surrounding structure thoroughly inspected for acid damage.
