Narrative:

Another base mechanic called me asking about an inspection that was deleted from [software]. Stated that his eps cap check was overdue. The required 12 month cap check inspection was not on the status sheet when he was doing his annual records audit. I then checked my aircraft records and found the same issue. The day emergency power supply routine test; ( that you did by pushing the eps test button for 5 seconds looking for a green light ); was now in fact a 180 day removal/replacement for routine test. I have to assume that meant cap check. When you check the D form on the aaip; the intervals reference 180 days. When you look at the references amm 12-a-24-52-51-00A-920A-a task 24-50/70 it states that the cap check is a 12 months requirement. Task # 46i0500-30 D 5330 - 180 day emergency power supply routine test. That is a function check by pushing the button for 5 seconds and looking for a green light. I called the appropriate people and got message machines. I was trying to get clarification if the inspection was corrected. The e-mail I got was that [company] was using the most conservative time to do the cap check. As per the amm and the manufacturer the cap check is to be done every 12 months. This lacks the most common sense and a lack of willingness to follow the manufacturer recommendation. The inability to make clear the requirements of checking. Or look at the requirements and think; the description is not correct because the reference says 12 month cap check. Everything you do to maintain an aircraft is reference. No reference you have to look it up to see how to do an inspection or a service. This same issue could happen the next time a mechanic checks a status sheet and see's the [test] is due ( emergency power supply routine test ) push the button. As a note the eps is not due a cap check for another 90 days per the manufacturer and amm.
