Narrative:

When replacing the #2 radio altimeter transmitter receiver; I found the rack driver/extractor assembly and insert were missing. A check of the ipc 34-37-00-078 item #131; 132A shows that these parts are only effective 661 to 699. My effectivity was 113. At ZZZ we had but not. Even if both parts were on hand they could not be used due to the effectivity range. Note: the #2 radio altimeter transmitter receiver is secure with the knurled box hold down nuts. I contacted my lead and supervisor. I was directed to contact maintenance services; which I did. I explained the problem to all. I believe that there is an error in the ipc.
