Descripción:
The aircraft was on a corporate flight from Philadelphia International Airport, USA, to Toronto International Airport when it crashed, 7.6. nm from the threshold of runway 24R while being vectored for an ILS approach.
The aircraft was observed to descend steeply from cloud and execute a series of abrupt, rolling movements, before striking the ground in a nose low, inverted attitude. A severe fire followed. The two crew members and three passengers die in the crash.

The investigators noted that there are indications of a pre-impact internal failure in the low pressure compressor of the right engine. The cause of this could not be determined.
There are also indications that the left engine was flamed out and windmilling at impact. The cause of this could not be determined.
It was also noted that wing anti-ice was not operating at impact, while icing conditions were present along the flight path of N99S as it descended and approached the localizer.
