SUPPLEMENTARY INFORMATION:  

REGULATORY TEXT:   80-01-07 R1 ROCKWELL INTERNATIONAL: Amendment 39-3658 as amended by Amendment 39-3774. Applies to Rockwell Model NA 265-60 and NA 265-80 airplanes equipped with the Raisbeck Mark Five modification in accordance with STC SA687NW or STC SA847NW. To prevent failure of the wing flap support structure accomplish the following:

A. On or before 430 landings after modification by The Raisbeck Group STC SA687NW, unless already accomplished, replace the outboard flap track support plates in accordance with FAA approved Raisbeck Group Service Bulletin No. 17.

B. If the flap system was previously affected by AD 79-13-02, the number of landings specified in Paragraph A may be increased by the total number of landings accomplished with inoperative flaps.

C. On or before 10 further landings, unless previously accomplished, perform an eddy current inspection of the flap track support structure in accordance with FAA approved Raisbeck Service Bulletin No. 18, Rev. B, on airplanes having the following serial numbers: 306- 005, 006, 012, 024, 050, 071, 109, 116, 119, 122, 380-025. For all other serial numbers, perform the above inspection prior to 100 landings after modification by Raisbeck STC SA687NW or STC SA847NW. If cracks are found, immediately inform William M. Perrella, Engineering and Manufacturing Branch, FAA Northwest Region, telephone (206) 767-2516. Before further flight, repair cracks in accordance with a method approved by the Chief, Engineering and Manufacturing Branch, FAA Northwest Region.

D. Effective before further flight, the full flap extension speed is reduced from 180 knots IAS to 160 knots IAS and the 20 degree flap extension speed is reduced from 225 knots IAS to 180 knots IAS. Install a placard in full view of the flight crew which specifies these speeds.

E. The life of the flap track support structure after modification by the Raisbeck Group STC SA687NW or STC SA847NW is limited to 900 landings, except for airplane S/N 306-116 which is limited to 450 landings.

F. Reinspect the flap track support structure for cracks in accordance with FAA approved Raisbeck Service Bulletin No. 18, Rev. B, or methods approved by the Chief, Engineering and Manufacturing Branch, FAA Northwest Region, at intervals not to exceed 100 landings.

G. Alternate modifications which provide an equivalent level of safety may be used when approved by the Chief, Engineering and Manufacturing Branch, FAA Northwest Region.

H. Modification of the flap support structure per FAA approved Raisbeck Service Bulletins 17, dated October 5, 1979; 19, Rev. B, dated April 28, 1980; and 23, dated November 30, 1979, constitutes terminating action under the provisions of this AD. Equivalent modifications are acceptable if approved by the Chief, Engineering and Manufacturing Branch, FAA Northwest Region. If the optional bolts listed in Paragraph III of Raisbeck Service Bulletin 23 are used, they must be replaced at intervals not exceeding 900 landings.

The manufacturer's specifications and procedures identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1).

All persons affected by this directive who have not already received these documents from the manufacturer, may obtain copies upon request to The Raisbeck Group, 7777 Perimeter Road, Seattle, Washington 98108.

Amendment 39-3658 became effective upon publication in the Federal Register and was effective earlier to all recipients of the emergency AD dated October 26, 1979.

This Amendment 39-3774 becomes effective June 3, 1980.
