From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry 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. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

While passing through FL180, during the descent for a landing at Tampa, Florida, the aircrew heard a loud bang and the radar system failed. It was an otherwise normal approach to landing, in clear sky, with no turbulence. The aircraft continued to handle normally and the subsequent landing was without incident. A post flight inspection of the aircraft noted the nose radome was dented in and cracked. It appears the inner ply of the radome had separated from the outer shell and this resulted in a two foot diameter delamination, and the front tip of the radome to cave in. No evidence was found of any bird or other foreign object impact. A review of the aircraft’s maintenance record indicates the subject radome was installed on October 21, 2003. Furthermore, the records do not indicate any history of related problems.
