MT Minimum.Time
MTBF Mean.Time.Between.Failures..A.performance.
figure calculated by dividing the total unit flying
hours.(airborne).accrued.in.a.period.of.time.by. the.number.of.unit.failures.that.occurred.during. the.same.time..Where.total.unit.hours.are. available,.this.may.be.used.in.lieu.of.total.unit.
flying hours.
MTBO Mean Time Between Outages
MTBR (.1.).Mean.Time.Between.Removal..
(.2.).Mean.Time.Between.Repairs..A.performance.
figure calculated by dividing the total unit flying
hours.accrued.in.a.period.by.the.number.of.unit. removals.(scheduled.plus.unscheduled).that. occurred.during.the.same.period.
MTBUR (.1.).Mean.Time.Between.Unscheduled.Removal.. (.2.).Mean.Time.Between.Unit.Replacements..A. performance figure calculated by dividing the total unit flying hours (airborne) accrued in a period by.the.number.of.unscheduled.unit.removals.that. occurred.during.the.same.period.

calculated.by.dividing.the.summation.of.times.to.
failure.for.a.sample.of.failed.items.by.the.number.
of.failed.items.in.the.sample..The.same.item.
failing.N.times.constitutes.N.failed.items.in.the.

calculated.by.dividing.the.sum.of.the.active.repair.
elapsed.times.accrued.in.a.period.on.a.number.
of.designated.items.by.the.number.of.these.items.
repaired.in.the.same.period.
