A former pilot, Kurt Deetz, said the crash was probably due to bad weather, rather than mechanical problems.
“The likelihood of a catastrophic twin-engine failure on that aircraft — it just doesn’t happen,” Deetz told the Times.

First responders were quick to prevent a second tragedy form occurring after arriving on the scene when they managed to quickly put out the rapidly spreading fire caused by the impact of the crash.
"Our firefighters hiked into the accident site with their medical equipment and hose lines to extinguish the stubborn fire as it included the brush fire … and the helicopter,” said LA County Fire Chief Daryl Osby.
“The fire also included magnesium, which is very hard for firefighters to extinguish because magnesium reacts with oxygen and water.”
The investigation will now look closely at both the aircraft and the pilot in determining the cause of this fatal flight.
That pilot was beloved by many, who expressed their shock and sadness.
"Thank you for being such great motivation while I was getting my PPL," said one.
"Thanks for always chatting with me when you flew in 72 and inspiring me to become a great helicopter pilot. Everyone will really miss you."
INVESTIGATION
The Los Angeles County Sheriff's Office and the National Transportation Safety Board (NTSB) are investigating the crash.
Lockheed Martin said it was also investigating the incident, as Sikorsky is owned by the defense contractor.
Sikorsky tweeted: "We extend our sincerest condolences to all those affected by today’s Sikorsky S-76B accident in Calabasas, California."
"We have been in contact with the NTSB and stand ready to provide assistance and support to the investigative authorities and our customer."
"Safety is our top priority; if there are any actionable findings from the investigation, we will inform our S-76 customers."
The NTSB said investigators plan to look at the pilot's history, the maintenance records, and any other information on the helicopter's owner and operator.
KOBE'S HELICOPTER
The helicopter was registered and operated by Island Express Holdings and Island Express Helicopters, which runs a fleet of helicopters that fly the 15-minute tourist route between San Pedro, CA, and Santa Catalina Island.
The company has been linked with two fatal crashes inlcuding one in 2008, where a helicopter filled with sightseers crashed on the west coast of Santa Catalina Island, killing three people and injuring three others.
The tour helicopter, a Eurocopter AS 350, operated by Island Express was carrying five passengers and a pilot.
Federal officials concluded that a turbine blade fatigue fracture was the probable cause of the accident.
Back in 1985, a helicopter operated by Island Express collided with another helicopter from San Pedro after picking up passengers in Avalon, Catalina’s largest town.
One person was killed and 11 people were injured.
