From the Wikipedia article
Atlantic Southeast Airlines Flight 4951 was a Bombardier CRJ900 carrying 60 passengers and 4 crew members on board on a flight from Atlanta to White Plains on 25 September 2010, commanded by Captain Jack Howard Conroyd Jr. (English: Jack Howard Conroyd, Jr.), aged 55 (born 24 March 1955 in the city of Hampton), with 8 years of experience with the United States Air Force and 24 years as a pilot for the company, and First Officer Larkin Ray Newby (English: Larkin Ray Newby), aged 33 (born 16 November 1976 in the city of Bellevue), with 12 years of experience with the company.
On approach to White Plains Airport the aircraft's crew lowered the landing gear, but the right rear wheel stayed stuck in the aircraft; the cockpit crew then tried to lower the right rear wheel, but it did not come down. The crew then thought it was a fault in the landing gear light, but air traffic control at White Plains Airport confirmed that the aircraft's right rear wheel had not come down, so the crew decided to fly to an airport with longer runways, and at that point John F. Kennedy International Airport was the only airport, so the crew decided to land at a speed of 135 knots/h (250 km/h). Passenger Chase Benzenberg, aged 45, was filming with his mobile phone what was happening on board the aircraft. The aircraft landed and came to a stop, and all 64 passengers and crew survived unharmed.

NTSB narrative
The right main landing gear door was found restricted against the fuselage wheel well body fairing. During a test gear swing following the incident, the door jammed again. According to the manufacturer, if improperly positioned, the door seal could wear and eventually cause the door to become jammed against the fairing and prevent extension of the main landing gear.
Probable cause
The probable cause of the incident was the restriction of the right main landing gear door against the fuselage wheel well body fairing which prevented the extension of the right main landing gear.
