life which correlates to the predicted repair and service life to ensure the public is not endangered Typically an original equipment manufacturer (OEM) calculates a mean time between failure (MTBF) and possibly a mean time to failure (MTTF) prediction These calculations assume all components are new, or considered as “unused”, at the point of introduction into flight use and that no useful component life and/or any “unsafe” component conditions have been used For example it is therefore essential that counterfeit, recycled and fraudulent components which have had potentially some of their ”useful life” consumed and which may also be malfunctioning are not purchased for use in aerospace, defence and high performance (ADHP) industries I n tern ati o n al E l ectro tech n i cal C o
