Narrative:

Aircraft #1, an small aircraft X, was cleared for a straight-in landing while 7 mi from runway 29, to call 4 mi final. At 4 mi, an small aircraft Y approached from the left rear belly-up to aircraft X and passed within 100 ft, cutting in front of aircraft X. At this time, the small aircraft Y contacted the tower and was cleared to land. When I asked the tower why the small aircraft Y had not contacted the tower before entering the air traffic area, the answer given was 'he was still with center.' the Y said he never saw us in small aircraft X. This is the second time this has occurred to me at this airport, in the same place and with the same excuse offered by the tower 'he was still with center.' the time before, aircraft 2 was an air carrier light transport with 19 people aboard. In each case, the airport was VMC and no reason can be found for the center (ZLA) to not release the aircraft to the local controller prior to reaching the air traffic area. Recommendations: 1. Center release aircraft to local controller when the airport is reported 'in sight' and prior to 5 mi from the airport. 2. No more than 1 aircraft allowed on the straight- in final at a time within the air traffic area.

Original NASA ASRS Text

Title: NMAC AT NON APCH CTL TWR FAC.

Narrative: ACFT #1, AN SMA X, WAS CLRED FOR A STRAIGHT-IN LNDG WHILE 7 MI FROM RWY 29, TO CALL 4 MI FINAL. AT 4 MI, AN SMA Y APCHED FROM THE L REAR BELLY-UP TO ACFT X AND PASSED WITHIN 100 FT, CUTTING IN FRONT OF ACFT X. AT THIS TIME, THE SMA Y CONTACTED THE TWR AND WAS CLRED TO LAND. WHEN I ASKED THE TWR WHY THE SMA Y HAD NOT CONTACTED THE TWR BEFORE ENTERING THE ATA, THE ANSWER GIVEN WAS 'HE WAS STILL WITH CTR.' THE Y SAID HE NEVER SAW US IN SMA X. THIS IS THE SECOND TIME THIS HAS OCCURRED TO ME AT THIS ARPT, IN THE SAME PLACE AND WITH THE SAME EXCUSE OFFERED BY THE TWR 'HE WAS STILL WITH CTR.' THE TIME BEFORE, ACFT 2 WAS AN ACR LTT WITH 19 PEOPLE ABOARD. IN EACH CASE, THE ARPT WAS VMC AND NO REASON CAN BE FOUND FOR THE CTR (ZLA) TO NOT RELEASE THE ACFT TO THE LCL CTLR PRIOR TO REACHING THE ATA. RECOMMENDATIONS: 1. CTR RELEASE ACFT TO LCL CTLR WHEN THE ARPT IS RPTED 'IN SIGHT' AND PRIOR TO 5 MI FROM THE ARPT. 2. NO MORE THAN 1 ACFT ALLOWED ON THE STRAIGHT- IN FINAL AT A TIME WITHIN THE ATA.
