Narrative:

After landing at mex, the F/east reached down to check the rudder trim at 0 and said, 'my god, the rudder trim is 2 1/4 units out of trim to the right.' this was about 1/2-way down the taxiway to the gate. The copilot said he thought he had added a little right trim climbing out of aca, but didn't think it was that much. Then he said he might have tried to reset the trim after clearing the runway, but he wasn't sure. There was lot of discussion about which way he might have tried to turn the trim, but he wasn't sure, and since 2 1/4 units is out of limits and the forthcoming mex takeoff is so critical in the large transport, I had a full control and flap check done on the aircraft. Also, there had been a slight shudder of the aircraft after takeoff as the flaps approached 5 degrees and then again as they went to 2 degrees, so I felt there might possibly be some flap problem and that should be checked also. A full check was done and nothing more was found. The trim on the next leg was normal. The lack of standardization of first officer-F/east responsibility cost us a 1 hour delay and a full maintenance check.

Original NASA ASRS Text

Title: ACFT INSPECTION CREATES A DELAY ON DEP.

Narrative: AFTER LNDG AT MEX, THE F/E REACHED DOWN TO CHK THE RUDDER TRIM AT 0 AND SAID, 'MY GOD, THE RUDDER TRIM IS 2 1/4 UNITS OUT OF TRIM TO THE RIGHT.' THIS WAS ABOUT 1/2-WAY DOWN THE TXWY TO THE GATE. THE COPLT SAID HE THOUGHT HE HAD ADDED A LITTLE RIGHT TRIM CLBING OUT OF ACA, BUT DIDN'T THINK IT WAS THAT MUCH. THEN HE SAID HE MIGHT HAVE TRIED TO RESET THE TRIM AFTER CLRING THE RWY, BUT HE WASN'T SURE. THERE WAS LOT OF DISCUSSION ABOUT WHICH WAY HE MIGHT HAVE TRIED TO TURN THE TRIM, BUT HE WASN'T SURE, AND SINCE 2 1/4 UNITS IS OUT OF LIMITS AND THE FORTHCOMING MEX TKOF IS SO CRITICAL IN THE LGT, I HAD A FULL CONTROL AND FLAP CHK DONE ON THE ACFT. ALSO, THERE HAD BEEN A SLIGHT SHUDDER OF THE ACFT AFTER TKOF AS THE FLAPS APCHED 5 DEGS AND THEN AGAIN AS THEY WENT TO 2 DEGS, SO I FELT THERE MIGHT POSSIBLY BE SOME FLAP PROB AND THAT SHOULD BE CHKED ALSO. A FULL CHK WAS DONE AND NOTHING MORE WAS FOUND. THE TRIM ON THE NEXT LEG WAS NORMAL. THE LACK OF STANDARDIZATION OF F/O-F/E RESPONSIBILITY COST US A 1 HR DELAY AND A FULL MAINT CHK.
