Narrative:
A McDonnell Douglas MD-83, registration N807WA, suffered a right hand main landing gear collapsed during landing rollout at Alexandria International Airport, Louisiana, USA. Due to the gear failure, the right wing dragged on the runway creating a friction fire which was quickly put out by the airport rescue and firefighting personnel
The aircraft operated on a flight on behalf of the U.S. Immigrations and Customs Enforcement and originated from Chicago-O'Hare International Airport.

The landing gear cylinder fractured under normal landing loads due to the presence of a fatigue crack on the forward side of the cylinder in an area subject to an AD inspection for cracks (AD 2004-05-03). The most recent AD inspection of the cylinder was performed 218 landings prior when the fatigue crack was large enough to be detectable. A previous AD inspection performed 497 landings prior to the accident also did not detect the crack that would have been marginally detectable at the time.

PROBABLE CAUSE: "The failure of the right main landing gear under normal loads due to fatigue cracking in an area subject to an FAA Airworthiness Directive that was not adequately inspected."
