JetBlue flight 29, an Embraer ERJ-190 (registration N273JB) from Washington National to Nassau, failed to show nose gear down and locked so the pilot decided to go around and make a low approach to allow visual inspection.
When I was a kid I was on a flight on approach to New York where the same thing happened, the nose gear was down and it was the indicator that was off (although the same precautions were taken as though the gear wasn’t).
They determined that the gear was not extended. It was nearly completely inside the wheel well. And since they weren’t able to rectify the situation, preparations were made to land with the gear up.
The procedure is to land while keeping the nose of the aircraft up as long as possible, and then lowering the nose onto the runway. That limits the impact, the speed, and the length of time that the aircraft’s nose is moving on the ground. Foam was applied to reduce the risk of fire.
The aircraft was evaucated, and none of the 93 passengers and four crew were hurt. Can’t say the same for the aircraft.
