Key Takeaways:

A deadly Cessna Citation S550 crash in San Diego killed all six occupants and caused significant damage to residential properties and injuries on the ground.
Investigators are focusing on the lack of a current altimeter setting at Montgomery-Gibbs Executive Airport (KMYF) as a potential contributing factor, given heavy fog and low visibility conditions.
The airport's automated weather system (ASOS) was out of service and its control tower closed, meaning the pilot was not provided with an altimeter setting, and ADS-B data shows the jet descended below the published glideslope before hitting powerlines.

Authorities investigating the deadly crash of a Cessna Citation S550 in San Diego on Thursday are looking at the possibility that a lack of current weather, specifically an altimeter setting at the destination airport, may have contributed to the accident.

There was heavy fog and low visibility in the area at the time of the crash. The pilot was attempting to fly the RNAV GPS approach to Runway 28R at Montgomery-Gibbs Executive Airport (KMYF).
