Dear Mr. Allen:
This will supplement our April 28, 1965, acknowledgement of your letter of April 22, 1965, reference B-80-96, relative to the Board's investigation of the accident involving Flying Tiger Line Lockheed 1049H, N6915C, at San Francisco, California, on December 24, 1964.
An airworthiness directive was issued on May 14, 1965, requiring disassembly and inspection of each radio transfer switch assembly, F/N 319122 for wire clippings, within 300 hours time in service.
We believe that this action will preclude difficulties associated with contamination.
Sincerely yours,
/s/ George S. Moore
George S. Moore
