Narrative:

I have written previously on mechanical malfunctions on our B-737's. Thrust reversers were a large part of my other reports; [aircraft] this morning had a reverser light upon taxi out. I have described this issue in great detail in previous reports. This recurring reverser issue on our fleet caused a two hour delay on three separate [flight] legs on my sequence today. On this aircraft; I personally checked the engine accessory unit (eau); with our mechanics. Three separate errors were indicated on the eau for the right engine; left sleeve sync lock pwr (power); right sync-lock pwr; hyd iso (isolation) valve sensor. As I previously indicated; the flight manual indicates that 'multiple malfunctions' are require for an in- flight reverser deployment. These error codes; I believe; are one if not more of the multiple malfunctions that could lead to an in-flight reverser issue very possibly leading to a hull loss. I have communicated at length with our air carrier engineering personnel and nothing as of yet has been done on this chronic B-737 reverser issue. It is my fear; we as company aviators are being forced to fly aircraft with potentially serious mechanical issues that even though individuals like myself point out; and get actively involved in [trying] to address; fail to be given the attention they deserve.

Original NASA ASRS Text

Title: A B737-800 Captain reports about recurring multiple malfunctions involving the Engine Thrust Reverser System. The P5 aft overhead reverser light intermittently illuminates when throttles are advanced during taxiing or takeoff; causing low speed abort. The problem has also occurred after landing. The problem (warning) recurs even after the Engine Accessory Unit (EAU) is reset.
