I believe this is the incident in which the runway threshold was displaced so that crews could perform maintenance.

The threshold was marked in a non-standard manner with very small Xs.

The crew initiated the first go around because they reported men and equipment working on the runway.

Instead of an explicit warning from the tower that only part of the runways was available the tower told the crew that the runway was open. The crew then attempted another approach utilizing the runway full length and were instructed to go around.

I saw the pictures of the runway with the Xs before and after they were enlarged. Many pilots would have made a similar error.

When an airport operator closes just a portion of a runway they should take extra care to ensure that pilots understand exactly what portion of a runway is available. There may or may not have been a notam published but a printed notice amid three pages of other low priority errata is insufficient warning.

I would apportion the majority of the blame for this incident to the airport operator, the local controller and the flight crew, in a descending order.
