REGULATORY TEXT:  
60-13-01 DOUGLAS: Amdt. 173 Part 507 Federal Register June 24, 1960. Applies to All DC-8 Series Aircraft.

Compliance required as indicated.

Several cases of fuel dump chute oscillation have occurred during extension and retraction of the chutes. This has caused cracking of the chutes which may create a hazardous condition by allowing fuel impingement on the wing and flap when dumping fuel. Oscillation of dump chutes occurs at speeds in excess of 200 knots indicated airspeed. To prevent possible fuel dump chute cracking, the following action is required.

(a) No later than 10 days following publication of this airworthiness directive in the Federal Register, the maximum speed for fuel dump chute operation and fuel dumping is restricted to not more than 200 knots indicated airspeed and the following placard shall be posted in full view of the pilot:

"Do not exceed 200 KIAS when operating dump chute and dumping fuel."

The limitations section of the FAA approved airplane flight manual is hereby amended to incorporate this limitation.

(b) Not later than the next periodic inspection ascertain that the dump cable control system is properly rigged in accordance with Douglas drawing No. 7651290 BS change.

(c) The 200 knots indicated airspeed restriction may be removed from those aircraft which have been reworked in accordance with Douglas Service Bulletin 28-16, "Fuel-Fuel Dump System and Controls".

(Douglas telegraphic alert Service Bulletin No. A28-16 covers the above speed limitation.)

Revised January 25, 1961.
