BHT [Medium Aircraft Tech Folk] in DFW had no problem with this idea, but still couldn't see [or admit] that they should also do it??
In Iran we were having a high number of instrument light failures on our AH1-
Js. With the lights inoperative the helicopters could not fly at night which really effected our training program. I did a design analysis on the power supply and found a design error on the part of the power supply vendor.
This problem was exacerbated by the installation instructions, which lead to the crushing of the power supply and the dislodging of one or more of the electrical components on the circuit board..
I notified Bell about it and they indicated that they were going to change vendors. They never changed vendors nor did they modify the installation instructions. I left the program a year later and we were still having the same problem.
