AE 135 in Gear Up Landing at Logan

American Eagle Flight 4539, an Embraer EMB-135, missed its first approach when airfield crews saw sparks during the landing at Boston’s Logan Airport before the crew pulled up on June 20. The aircraft was inbound from Toronto. Just as the aircraft touched down debris fell away from the aircraft during the 8:20 a.m. incident. As the aircraft did two fly-bys, controllers could see no visible damage to the gear before the aircraft landed without further incident.
The National Transportation Safety Board said in its preliminary report the crew reported an indication that the gear was down and locked but right before touchdown, they noticed a landing gear lever disagree. They executed a go-around and mechanically lowered the landing gear. They were able to get the gear down and locked and got a visual confirmation that the gear was down. The flaps would not extend owing to damage from contacting the runway on the initial landing. There were 37 passengers and three crew members on board. No injuries were reported. Eye witnesses to the first landing stated that they did not see the gear down on the approach.
