Aircraft Accident/Incident Report
Jamaica, New York 11430

NTSB Narrative Summary Released at Completion of Accident
While on final, the first officer had trouble trimming the airplane. The captain attempted to trim the airplane via his yoke switch and the manual trim handle, with no success. A go-around was executed. The crew ran the checklist, but control of the stabilizer trim was not regained. The crew pulled circuit breakers H11 and H20, and then reset them. The stabilizer trim was still inoperative. The crew reset the trim cutout switches twice, and normal operation of the stabilizer trim was reestablished. The left stabilizer position transmitter, and the right stabilizer position transmitter were out of calibration. Also, the left stabilizer trim control module (STCM) was found to have a higher than normal leakage, and the connector for the corresponding shut-off valve was shorting across several of its pins due to skydrol incursion. No faults were identified for the right system except for the right-stabilizer-position transmitter. According to the operator, the system should have operated at half rate with the above discrepancy, but did not. There have been no reports of difficulties with the airplane's stabilizer trim system since the event.
NTSB Probable Cause Narrative
Total failure of the stabilizer control system for undetermined reasons.
