Incident at Calgary, AB


1997-06-23: On approach to Runway 28, the crew of UAL 1655 chose to overshoot because of an unsafe gear indication. As the a/c was in the overshoot, Tower observed that the left main gear was not down. The pilot indicated that he did not require CFR and the a/c landed safely at 2043Z and taxied clear of the runway onto Whiskey taxiway. UAL 1655 stopped there and unloaded the passengers onto buses. Tower changed the active runway to 16 and there were minimal delays to other a/c. UPDATE The gear failed to extend due to the uplock hydraulic lines being misrouted to the control module. Maintenance reinstalled the lines correctly and a gear swing revealed no problems. The lines had been replaced in Denver recently to correct damage from a tire failure on a previous flight.
