Narrative:

At approximately 200 ft above minimums, the elevator control felt sluggish. As I was distracted briefly, the aircraft drifted slightly to the left of track. At the same time we arrived at minimums, as I corrected to the right and descended for touchdown, I felt uncomfortable with the situation, therefore I executed a missed approach. At this point both the copilot and myself felt the left main gear touch the runway. On the climb out and level off, we realized that the primary trim was not responding, however, the alternate trim was working normally. The autoplt was used to shoot a complete approach to a runway 28L ILS landing without further incident. On doing a postflt, we noticed some damage to the left wingtip. It turns out that the primary trim was used for many airspeed changes during the approach and overheated the primary trim motor. It failed at just the wrong moment.

Original NASA ASRS Text

Title: AN ACR DC9 CAPT SCRAPED HIS L WINGTIP ON AN EVASIVE ACTION GAR.

Narrative: AT APPROX 200 FT ABOVE MINIMUMS, THE ELEVATOR CTL FELT SLUGGISH. AS I WAS DISTRACTED BRIEFLY, THE ACFT DRIFTED SLIGHTLY TO THE L OF TRACK. AT THE SAME TIME WE ARRIVED AT MINIMUMS, AS I CORRECTED TO THE R AND DSNDED FOR TOUCHDOWN, I FELT UNCOMFORTABLE WITH THE SIT, THEREFORE I EXECUTED A MISSED APCH. AT THIS POINT BOTH THE COPLT AND MYSELF FELT THE L MAIN GEAR TOUCH THE RWY. ON THE CLBOUT AND LEVEL OFF, WE REALIZED THAT THE PRIMARY TRIM WAS NOT RESPONDING, HOWEVER, THE ALTERNATE TRIM WAS WORKING NORMALLY. THE AUTOPLT WAS USED TO SHOOT A COMPLETE APCH TO A RWY 28L ILS LNDG WITHOUT FURTHER INCIDENT. ON DOING A POSTFLT, WE NOTICED SOME DAMAGE TO THE L WINGTIP. IT TURNS OUT THAT THE PRIMARY TRIM WAS USED FOR MANY AIRSPD CHANGES DURING THE APCH AND OVERHEATED THE PRIMARY TRIM MOTOR. IT FAILED AT JUST THE WRONG MOMENT.
