The airworthiness directive
60-06-02 BOEING: Amdt. 113 Part 507 Federal Register March 11, 1960. Applies to all 707 series aircraft operating in accordance with Parts 40, 41, and 42 of the Civil Air regulations.
Compliance required as indicated.
As a result of detailed examinations of flight recorder data subsequent to recent incidents involving 707 series aircraft, it has been determined that the prime power switch for the flight recorder, now actuated by the displacement of a landing gear oleo strut, does not insure all elements of the flight recorder to be operating at the start of the takeoff roll and continuing until the landing is completed at an airport. Therefore the following modification shall be accomplished as indicated.
Unless already accomplished, compliance required not later than May 15, 1960.
Install a three-position switch, AN 3027-8 type or equivalent, in the pilot compartment and connect to appropriate circuits in the flight recorder for "TEST-OFF-ON" functions. Switchpositions shall be appropriately marked.
Removal of the presently installed oleo actuated power switch is optional, and if not removed, it shall not be considered as an equivalent to the required three-position manually operated switch.
(Boeing Service Bulletin No. 77 (R-1) pertains to the circuitry revision.)
