Incident at Dallas, TX

Summary

1999-06-17: The crew of C-FBWX, a B727, were conducting a test flight out of Love Field in Dallas after the a/c had undergone a "C" check at a maintenance facilty there. When they tested the "leading edge devices - standby extension" procedure, the number 7 slat extended improperly. On a subsequent flap extension and retraction, the number 7 slat partially dislodged from its track and contacted slat number 6. The a/c went into a roll, but the crew was able to maintain control. They declared an emergency and carried out the "more than one leading edge device inoperative" landing. The flight landed safely and a report filed with the FAA. An SDR will be submitted to Transport Canada. OPI - System Safety UPDATE Maintenance and Manufacturing reported that: 1) There has been an SDR filed. 2) Morningstar's investigation revealed that the aft roller on one of the slat tracks had not been correctly installed. The attach bolt had missed the roller instead of going through it. The slat had been cyled several times on the ground without incident but during the flight test the roller departed the track when the slat was deployed. The slat installation had been dual inspected. 3) Dalforth has, apparently, taken disciplinary action. 4) Fed/Ex is now reported to be involved in its own investigation at Dalforth since they are the owners of C-FBWX (leased by Morningstar), and are concerned with QC issues raised by the incident.
