Issued Sep 26, 2003 ## NTSB investigations (1) From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. - [NTSB WPR12CA288](https://openairdocs.org/ntsb/WPR12CA288), Jun 24, 2012: Dg-Flugzeugbau DG-500MB (N505JL), Richland, WA, substantial damage. Probable cause: The failure of the spoilers to retract because the right wing spoiler’s lower plate became jammed, which resulted in the glider not having enough lift to make it to the runway surface. ## FAA accident and incident reports (2) From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong.
