REGULATORY TEXT:  
61-12-02 DOUGLAS: Amdt. 294 Part 507 Federal Register June 7, 1961. Applies to All Model DC-8 Aircraft powered with P&WA JT3C-6 and JT4A Series Engines.

Compliance required as indicated.

An instance has been reported wherein a takeoff was attempted with elevator gust lock engaged. It was found that the throttle interlock did not provide adequate restriction to limit engine thrust under the prevailing temperature condition. Unless already accomplished, the following modification or FAA approved equivalent, must be accomplished within the next 500 hours' time in service.

Modify the throttle interlock system to provide further restriction of the throttles when elevator gust lock is engaged by installing the following parts or equivalent:

Pushrod - Gust Lock Interlock Pedestal, P/N 3771190.

Adapter - Gust Lock Crank, P/N 4771191.

Arm, Gust Lock Interlock Pedestal, P/N 2772271-1 or -501.

Per Douglas Drawing No. 5640901 Changes "CI" and "CK" - "Pedestal Assembly - Accessory Controls".

(Douglas Service Bulletin No. A27-99, reissue No. 1, revision No. 2 dated July 19, 1961, also covers this same subject.)

This directive effective June 7, 1961.

Revised August 26, 1961.
