## Discrepancy

IAH - Crew reported that on approach that the nose landing gear had an unlock indication that flashed 8 to 10 times with several lound bangs. Maintenance performed an inspection of the gear and did not find any defects. The problem reoccured on flight 3604 on the same date. Maintenance adjusted the #1 nose landing gear proximity switch. The aircraft was then approved for return to service.
