Subject: Failure Rate Conversion
I have an MTBF figure for an LRU operating in A(IC) Airborne Inhabited Cargo enviroment of 6,000 hrs. I am going to operate it in the G(M) Ground Mobile enviroment. Does anyone know the conversion factor I use to translate A(IC) to G(M)?

Hi I am trying to find a failure rate model similar to other mechanical models in the Carderock mechanical reliability handbook. I realize that NPRD-95 has a direct tv installer couple of data points for bellows but they are GF environment (ours is naval unsheltered) and the failure rate is given independent of number of cycles, material, etc. I would expect those parameters to play a large part in the failure of a bellows. Thanks for your time. Bob Valerius
