The search resulted in cut ribbon cables. This circuit has been responsible for the accidental releasing of CO2 inside the LM2500 modules at least once per year per engine per ship. Two modifications to the release circuit have failed to resolve the problem. A suggested change to take away the automatic release was debated, then prototyped, and found to be a reliable solution. Yet U.S. Navy sailors still are being used to carry accidentally spent bottles of CO2, and their full replacements, from and into the engine rooms of these ships.
Modification is on hold.
Money was wasted getting people to Washington to talk about problems. Money was wasted in buying all of the forerunners to the present in-place Condition Assessment System. Money was wasted in trying to develop an engine controller to replace the poorly designed Free Standing Electronic Enclosure that comes with the LM2500 jet engine. Money was wasted putting illegible tech manuals in computer systems. Many efforts were made by NavSea to understand and rectify the problem, but usually each effort failed, most likely because the decision-making people had no working concept of electronic engineering.
