Implementation of THUMS and CBM in the Israeli Air Force—Lessons Learned

The implementation of THUMS and CBM capabilities in the Israeli Air Force was presented from the original 1990 vision through implementation and lessons learned to today. THUMS technology is a vital part of any aircraft. This capability allows observation “through a magnifying glass” into the deterioration mechanisms in critical systems of the aircraft. It should be recognized that even though THUMS is currently a quite mature product, work still remains to be done in tuning the severity levels, as well as better interpretation and understanding of the different helicopter component deterioration modes. It is recommended to learn from the lessons presented and to be proactive in any future THUMS program. The IAF will continue its activities toward reaching the discussed goals, which will safely pave the IAF road to cost-effective CBM, better mission readiness, and improved flight safety of its helicopter fleets.
