Narrative:

On this night I was assigned aircraft south/C and pmc. Both aircraft terminated with inbound write-ups, both having ram air door discrepancies, with APU electrical #1 unable to come on line. This night was hectic for all. We had a slat change on another aircraft as well as it had a c-chk wash as well as other aircraft with numerous inbounds, tires, and brakes. As I was changing this component, I had made a mental note to check 'compatibility of parts' computer. In an effort to help others instead of taking the time to drive to the other, side of the airport to check MD25, I forgot to check. Right after I troubleshot and determined this fix, I went to aircraft to fix an annoyance MEL on the #2 engine oil filter bypass light which is where I spent the rest of the night. Gentlemen, it is my fault. I should have finished one job before starting another. Callback conversation with reporter revealed the following information: the reporter stated that, in attempting to cover several jobs, the wrong generator control panel was installed in the P-5 overhead panel. The reporter said that several times attempts had been made to get to the 'compatibility computer' to order the correct part for the generator report, but some other problem would always pop up. The reporter stated the panel was removed and a replacement installed, but the removed part and installed part number were never compared.

THIS NIGHT WAS HECTIC FOR ALL. WE HAD A SLAT CHANGE ON ANOTHER ACFT AS WELL AS IT HAD A C-CHK WASH AS WELL AS OTHER ACFT WITH NUMEROUS INBOUNDS, TIRES, AND BRAKES. AS I WAS CHANGING THIS COMPONENT, I HAD MADE A MENTAL NOTE TO CHK 'COMPATIBILITY OF PARTS' COMPUTER. IN AN EFFORT TO HELP OTHERS INSTEAD OF TAKING THE TIME TO DRIVE TO THE OTHER, SIDE OF THE ARPT TO CHK MD25, I FORGOT TO CHK. RIGHT AFTER I TROUBLESHOT AND DETERMINED THIS FIX, I WENT TO ACFT TO FIX AN ANNOYANCE MEL ON THE #2 ENG OIL FILTER BYPASS LIGHT WHICH IS WHERE I SPENT THE REST OF THE NIGHT. GENTLEMEN, IT IS MY FAULT. I SHOULD HAVE FINISHED ONE JOB BEFORE STARTING ANOTHER. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THAT, IN ATTEMPTING TO COVER SEVERAL JOBS, THE WRONG GENERATOR CTL PANEL WAS INSTALLED IN THE P-5 OVERHEAD PANEL. THE RPTR SAID THAT SEVERAL TIMES ATTEMPTS HAD BEEN MADE TO GET TO THE 'COMPATIBILITY COMPUTER' TO ORDER THE CORRECT PART FOR THE GENERATOR RPT, BUT SOME OTHER PROB WOULD ALWAYS POP UP. THE RPTR STATED THE PANEL WAS REMOVED AND A REPLACEMENT INSTALLED, BUT THE REMOVED PART AND INSTALLED PART NUMBER WERE NEVER COMPARED.
