THE TWO CREWMEMBERS AND 13 PASSENGERS ABOARD WINGS WEST FLIGHT 628, AND THE TWO PILOTS ABOARD THE AERO COMMANDER WERE KILLED IN THE CRASH. PRELIMINARY ANALYSIS OF THE NATIONAL TRANSPORTATION SAFETY BOARD'S ONGOING INVESTIGATION OF THIS ACCIDENT INDICATE THAT FLIGHT 628 WAS PROCEEDING OUTBOUND FROM THE SAN LUIS OBISPO COUNTY AIRPORT ON A "CREPE ONE" DEPARTURE, WHICH REQUIRES DEPARTING TRAFFIC TO CLIMB TO CREPE INTERSECTION ON THE SAN LUIS OBISPO LOCALIZER COURSE BEFORE TRANSITIONING TO THE EN ROUTE FLIGHT PLAN. THE SAFETY BOARD'S INVESTIGATION TO DATE ALSO INDICATES THAT THE AERO COMMANDER WITH A FLIGHT INSTRUCTOR GIVING AN AIRCRAFT CHECKOUT TO ANOTHER RATED PILOT WAS PROCEEDING INBOUND TO SAN LUIS OBISPO COUNTY AIRPORT ON THE LOCALIZER COURSE TO RUNWAY 11, AND MAY HAVE BEEN MAKING A PRACTICE LOCALIZER APPROACH. CONSEQUENTLY, THE FLIGHT PATHS OF THE TWO AIR PLANES WERE DIRECTLY OPPOSED.

Safety Recommendation History
From: NTSB
To: FAA
Date: 12/4/1985
Response: The FAA responded that its Western-Pacific Regional Office had disseminated the contents of the Board's recommendation letter to the Flight Standard District Offices most likely to have contact with operators and fixed base operators using and operating in the vicinity of the San Luis Obispo County Airport. The Safety Board considers that action satisfactory and has classified the recommendation as "Closed--Acceptable Action." However, we believe that dissemination of the circumstances of the accident should be more widespread to enlighten pilots to the hazards of operations at uncontrolled airports with departure and arrival procedures similar to San Luis Obispo County Airport. The Safety Board believes that the various pilots, aircraft owners, and aircraft operators professional associations should disseminate the contents of this accident report to its members. In addition, those organizations should encourage their members to adhere to the recommended communications and traffic advisory procedures of the AIM for operations at uncontrolled airports and, where feasible, to request an IFR flight clearance, or at the minimum, traffic advisory service before departure.

WE BELIEVE THIS METHOD OF DISSEMINATION WILL MEET THE INTENT OF THE BOARD'S RECOMMENDATION, AND PROVIDE THE BROADEST DISTRIBUTION AND AWARENESS OF THE CONTENT OF THE BOARD'S RECOMMENDATION LETTER.
