Golden West Flight 261 departed Ontario, CA at 15:56PST for a VFR flight to Los Angeles. At 16:04 the crew contacted LAX arrival and reported over Rose Hills. The flight was then cleared for the Terminal Control Area (TCA) and no. 2 arrival to runway 24L. At 16:05 the crew were advised that they had traffic 5,5nm in front of them climbing from 1500 to 3000 feet which was a police helicopter on a VFR flight. The arrival controller transmitted another advisory about the helicopter at 16:06, but there was no response. It appeared the Twin Otter had collided in flight at 2200 feet with a Cessna 150 aircraft (N11421). The Twin Otter was flying on a 250deg heading descending 300 feet/min at 146 knots airspeed while the Cessna was flying at 94 kts; the closing speed was 174 kts. The Cessna, operated by CessnAir Aviation had departed from Long Beach on a local training flight at 15:46. Both aircraft crashed. Debris caused some damage to houses and lawns near the crash site.
