A KLM Boeing 737-800, registration PH-BXD performing flight KL-1665 from Amsterdam (Netherlands) to Barcelona,SP (Spain), was climbing out of Amsterdam's runway 36L when after retracting the gear the crew did not receive indication the nose gear had locked into the up position. The crew stopped the climb at FL060 initially reporting a technical problem and returned to Amsterdam. The crew performed a low approach to runway 27 about 30 minutes after departure to have the gear inspected from the ground, then entered a hold at 3000 feet before positioning for a second approach and landed safely on runway 27 about 60 minutes after departure.

A replacement Boeing 737-800 registration PH-BGC reached Barcelona with a delay of 4 hours.
