| The inspection patches were instigated by the CAA several years ago,like the De Havilland Tiger Moth's in service today the CAA stipulated that over 100 doped inspection patches needed to applied at strategic points along the wings,these serve to keep a constant check on internal structure integrity,inspection of the control runs and general condition,this scenerio was started when a former crop spraying Tiger Moth broke up in flight during aerobatics in Australia,that particular aircraft had been subjected to agricultural chemicals that affected the integrity of the airframe,and so as always happens everyone owning old biplanes has suffered since.
Standard S.E.5A aircraft in service during WW.1 were considered expendable,and as such had very little airframe inspections,most did not last that long anyway ? as such their wings were just patched us as required,but they did not have set inspection patches like the Shuttleworth example which has to meet modern airworthiness requirements.
