That is his usual ride.
I am a VFR pilot (not only one here), and have flown in LA area years ago.
Reading the new what
FlightAware and
Flight Radar says:
Pilot was
EXTREMELY skilled, fully rated and an Instrument Instructor too (CFII in pilot terms).
Long time flying LA area, was intimately familiar with area.
He often flew Kobe back and forth from home and practice.
===========OPINION ALERT!==========
While I did consider Pilot Error as cause, looking at data available I now consider this a very low probability.
This chart is from ABS-D transpoinder data transmitted by N72EX (helicopter ID):
The last 14 seconds show a rapid decent GREATER THAN 1000 feet per minute (FPM, left side numbers).
There was a brief slowdown of fall 4 seconds before impact, but when impact happened heli was going almost 5000 FPM (about 50mph) straight down.
Controlled Flight into Terrain (CFIT) are almost always level or in a more linear rate. Aircraft descend to for landing rarely more than 3000FPM, typically 2000~2500FPM. They are also usually straight line, but N72EX was turning as it went down.
And that upward peak 3 seconds before impact is typical for an emergency auto-rotation landing.
My OPINION is I now strongly believe a mechanical failure caused this crash.
