The plane crash in Northeast Philadelphia Friday that killed seven and injured 24 also damaged 343 homes, according to a report.
6ABC reported that city officials claim that 343 homes in Northeast Philadelphia were "impacted in some way," by the crash. Four homes were completely destroyed, six others had major damage while an additional 11 homes had some damage.
Cottman Ave. remains closed for several blocks at the crash site while the investigation continues. The National Transportation and Safety Board (NTSB) is leading the joint investigation and hopes to have it wrapped up by Wednesday.
The NTSB also released an image of the cockpit voice recorder which is being examined and tested in Washington D.C. No updates were provided about what audio may have indicated from the device and if it can shed any light as to the cause of the crash.
U.S. Transportation secretary Sean Duffy, who has been in his role for a little more than a week, has had to deal with two plane crashes - one in Washington D.C. last Wednesday that occurred midair between an American Airlines passenger jet and a U.S. Army Black Hawk helicopter that resulted in 67 fatalities, and the crash in Philadelphia on Friday night.
Once they are able to recover information from cockpit voice recorder, the investigative arms of the NTSB and the Federal Aviation Administration (FAA) will begin to answer questions related to the crash.
"They will look at the weather. Were there any medical concerns? Was there any technical or mechanical issues on the airplane," Duffy said.
While there is no data recorder on the Learjet 55, there is an Enhanced Ground Proximity Warning System that could provide some data about the crash that has been recovered.
He also announced that a preliminary report on the investigation is expected within 30 days.
While there have not been any updates to the fatality and injury totals, city officials are warning those numbers could still rise and there are some reports - both in the media and on social media - of individuals who are missing who were in the area at the time of the crash.
The six people on board the plane who perished were all Mexican nationals. The plane's captain Alan Montoya, co-pilot Josue Juarez, Dr. Raul Meza, paramedic Rodrigo Padilla, 11-year old patient Valentina Guzman Murillo - who had been treated at Shriner's Hospital in Philadelphia - and her mother Lizeth Murillo Osuna.
The person who was killed in their car has not yet been publicly identified.
