Narrative:
I was given a job to perform; to repair broken sealant of slant pressure panel in the r-hand wheel well. I pulled up the appropriate reference for the removal of the old sealant and for application of new sealant ahd coating. Upon application of sealant; the electric connector was in the position that made access to that area of the panel difficult to apply the sealant properly and I disconnected the plug to gain a better access to the panel. The break in the seal was directly under the plug I removed. After the repair; I reinstalled the connector plug. I thought I had it back in properly; because I clocked it left and right to catch the keyways and when I felt it fall in; I began to screw it down to secure it. I got about 4 full turns on it by hand and then used my channel locks to make sure it was secured; so I thought; I got about 1 full turn more with it. I was informed that the aircraft showed electrical faults; because of my crossthreading of the connector it wasn't making proper contact; and looking back on the reference; I pulled up for the seal there was no provision in it for removing the plug; and I did not. Through rushing to get the task done; make a non routine item stating the plug was removed for facilitation of maintenance.

Title: A B717 DISPLAYED NUMEROUS ELECTRICAL FAULTS AFTER A R WHEEL WELL ELECTRICAL CONNECTOR WAS DISCONNECTED TO FACILITATE SEALANT REPLACEMENT ON THE SLANT PRESSURE PANEL. FOUND CONNECTOR CROSSTHREADED AND PINS NOT ENGAGED.
Narrative: I WAS GIVEN A JOB TO PERFORM; TO REPAIR BROKEN SEALANT OF SLANT PRESSURE PANEL IN THE R-HAND WHEEL WELL. I PULLED UP THE APPROPRIATE REF FOR THE REMOVAL OF THE OLD SEALANT AND FOR APPLICATION OF NEW SEALANT AHD COATING. UPON APPLICATION OF SEALANT; THE ELECTRIC CONNECTOR WAS IN THE POS THAT MADE ACCESS TO THAT AREA OF THE PANEL DIFFICULT TO APPLY THE SEALANT PROPERLY AND I DISCONNECTED THE PLUG TO GAIN A BETTER ACCESS TO THE PANEL. THE BREAK IN THE SEAL WAS DIRECTLY UNDER THE PLUG I REMOVED. AFTER THE REPAIR; I REINSTALLED THE CONNECTOR PLUG. I THOUGHT I HAD IT BACK IN PROPERLY; BECAUSE I CLOCKED IT L AND R TO CATCH THE KEYWAYS AND WHEN I FELT IT FALL IN; I BEGAN TO SCREW IT DOWN TO SECURE IT. I GOT ABOUT 4 FULL TURNS ON IT BY HAND AND THEN USED MY CHANNEL LOCKS TO MAKE SURE IT WAS SECURED; SO I THOUGHT; I GOT ABOUT 1 FULL TURN MORE WITH IT. I WAS INFORMED THAT THE ACFT SHOWED ELECTRICAL FAULTS; BECAUSE OF MY CROSSTHREADING OF THE CONNECTOR IT WASN'T MAKING PROPER CONTACT; AND LOOKING BACK ON THE REF; I PULLED UP FOR THE SEAL THERE WAS NO PROVISION IN IT FOR REMOVING THE PLUG; AND I DID NOT. THROUGH RUSHING TO GET THE TASK DONE; MAKE A NON ROUTINE ITEM STATING THE PLUG WAS REMOVED FOR FACILITATION OF MAINT.
