 Sausalito VOR frequency. The No. 1 ADF receiver was tuned to a frequency of 379 kcs. The San Francisco Airport ILS outer marker frequency is 379 kcs. The No. 2 ADF receiver was tuned to approximately 332 kcs., the San Francisco Gap Homer frequency.

The readings taken from the captain's course line indicator (Collins, Type 331A-2C) were as follows: The lubber line or magnetic heading arrow was found on 218 plus or minus 4 degrees; the VOR course selector arrow was pointing to 268 degrees. However, subsequent internal examination of the unit indicated the course selector was set at 298 plus or minus 10 degrees when the internal mechanism was damaged at impact.

The readings taken from the copilot's course line indicator which was more heavily damaged were as follows: The magnetic heading arrow was determined to be 218 degrees; the VOR course selector arrow was pointing to 028 degrees.

The ADF dual bearing indicator was heavily fire damaged. The needle pointer readings were as follows: The No. 1 pointer was reading a relative bearing of 270 to 280 degrees; No. 2 pointer was reading a relative bearing of 110 degrees. One recovered loop mechanism indicated a relative bearing of 123 degrees.

The fire that followed impact was extinguished by local firefighting apparatus.

This was a non-survivable accident.

Following the accident, flights were conducted to correlate ground witnesses and traffic controller information. These flights pinpointed the probable speed and flightpath of Flight 282, and established that the initial left turn immediately after takeoff was in excess of 25 degrees of bank. Validation of times and rates of climb were also established by the flight tests.

Performance figures of the manufacturer indicate that this aircraft's rate of climb should have been in excess of 800 feet/minute from liftoff. The FTL chief pilot at SFO stated that in his experience similarly loaded L-1049H aircraft will normally climb between 400–500 feet/minute on departures from runway 28 at SFO. While no minimum rate of climb per mile was established for runway 28 departures at the time of the accident, the FAA has since specified that 250 feet/mile is the minimum acceptable. (See Attachments #2 and 4.)

A facility test was made of the San Francisco TVOR to determine what effect, if any, an aircraft taxiing in the vicinity of the TVOR antenna on the airport would have on the 287-degree radial reception by Flight 282. All known ground
