ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 83-04-02 FOKKER-VFW B.V.: Amendment 39-4569. Applies to Model F28 airplanes serial number 11003 and on. To prevent loss of aileron control, accomplish the following, unless already accomplished within the last three months prior to the effective date of this AD: 1. Within the next 50 hours time in service or one month, whichever occurs first after the effective date of this AD, perform a one time inspection of the aileron control cables in both the R.H. and L.H. wings for airplanes with more than one year's time from the date of manufacture in accordance with the following instructions: a. Open the main landing gear doors and flap shroud doors 81j, 81k, 82j, and 82k. b. Rotate the aileron control wheel in the cockpit to the full left-hand position. c. With the control wheel in this position, inspect the four aileron input cables at location of cable pulleys between stations 3100 and 3600 (illustrated parts catalog, chapter 27-10-01-05). Inspection must be performed with the aid of a mirror and a very strong light otherwise corrosion may remain undetected. d. If wires are broken or there are definite signs of corrosion in the cables, accomplish the actions of paragraph 2. e. Rotate the aileron control wheel in the cockpit to the full right-hand position and repeat the inspections described in paragraphs (c) and (d). 2. If corrosion on the cables is evident from the inspections of paragraph 1, above, accomplish the following: a. Disconnect the cable at the turnbuckle in the wheelwell per the F28 Maintenance Manual, chapter 27-11. b. Pull out the cable at the cable pulleys between stations 3100 and 3600. c. Carefully bend the cable one time at the location of the corrosion over a radius of one inch. If any wire breaks while being bent, replace the cable prior to further flight. d. If no wires failed during the bending test of paragraph 2(c), repeat the test by bending the cable in the opposite direction. If any wire breaks, replace the cable before further flight. e. If the cable is not rejected by the bending tests of paragraphs 2(c) or 2(d), inspect the cable for interior corrosion in accordance with the F28 Maintenance Manual, chapter 20-30-9. f. If interior corrosion is found, replace the cable before further flight. g. Remove any exterior corrosion and treat the cable in accordance with F28 Maintenance Manual, Chapter 20-30-9. h. Reconnect the turnbuckles in the L.H. and R.H. wheelwells and adjust the cable system in accordance with F28 Maintenance Manual, Chapter 27-11-00, and check the aileron for free and smooth operation. 3. Alternate means of compliance which provide an equivalent level of safety may be used when approved by the Manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region. 4. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections and/or modifications required by this AD. 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). This amendment becomes effective March 7, 1983. FOOTER:
