What crash does FAA SAIB CE-10-11 refer to?
From the details it sounds like the accident was N501N, a Cessna 310R that crashed on 10 July 2007 (NTSB Summary Report (PDF)).  This airplane had been previously written up for an anomaly with the weather radar and subsequently improperly released back into service.  The accident crew reported smoke in the cockpit and post-crash analysis revealed substantial electrical component damage, burned wire insulation, etc.
