9.17.3 Split pins should not be used more than once.
9.17.4 Unless otherwise specified airframe bolts should be tightened to
remove free-play, without causing distortion of the parts/ovalising of
tubes. Beware of the nut becoming ‘thread-bound’ at the end of the
thread. Additional washers may be required in such a case.
10. Repairs
10.1 If the aircraft is damaged, it is imperative that the full extent of the
damage is quantified by an appropriate person. In the case of flying
accident damage this MUST involve a BMAA inspector or the
manufacturer. Accidents must be reported to the AAIB and BMAA.
10.2 Damage can often extend well beyond the immediately obvious.
10.3 Careful strip inspection of components will often be prudent. Check for
bent fasteners, distortion of tubes, elongated holes and stress marks in
the anodizing of aluminium tubes.
10.4 Repair by replacement is the usual course of action, and as such
requires no special additional approval. However, repair of a particular
part by rework/ reinforcement/ welding etc is classified as a repair and
requires specific approval of the repair process from the manufacturer,
BMAA or CAA. On a simple aircraft like the Nynja it is normally far
simpler and cheaper to replace the damaged component.
10.5 Repairs to the Engine.
These should be carried out in accordance with the maintenance
manual for the engine fitted.
10.6 Repairs to Instruments.
Microlight aircraft instruments are not usually repairable and should be
replaced.
10.7 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. Fuel hose
forward of firewall must be fire-resistant. 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.
