Dear Mr. Gobeille: This is in reply to your letter of June 19, 1975, seeking a interpretation of Standard No. 124, *Accelerator Control Systems*, with regard to an accelerator control system which contains either elements in parallel or a complete parallel system.; The requirements of S5.2 of Standard No. 124 are met if, after severance or disconnection of any component of the accelerator control system, the throttle returns to the idle position within the time specified in S5.3, measured from the first removal of the opposing actuating force by the driver, *or* from the disconnection or severance. You are correct in your interpretation that Standard No. 124 is intended to protect against a single severance, and that there are no requirements in Standard No. 124 concerning the severance or disconnection of the remaining one(s) of two or more parallel elements in an accelerator control system.; Sincerely, James C. Schultz, Chief Counsel
