ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 86-24-06 BRITISH AEROSPACE: Amendment 39-5472. Applies to Models HP-137 MK 1 and Jetstream 200 Series (all serial numbers), and Model Jetstream 3101 (S/N 601-633, 635-646 and 648-654 inclusive) airplanes certificated in any category. Compliance: Required within 600 hours time-in-service (TIS) after the effective date of this AD, unless already accomplished. To prevent unacceptable aileron control vibration and aileron jamming, accomplish the following: (a) Inspect the special stud BAe P/N 13705E29 and nut BAe P/N A103-JT for tightness, visible thread length and punch marks, in accordance with Section 2. "Accomplishment Instructions" in BAe Mandatory S/B No. 27-JM-5257, dated June 6, 1986. (1) If the special stud and nut are secure, and the special stud end protrudes 1-1/2 to 2 threads beyond the nut and all three punch marks are visible, no further action is necessary. (2) If the special stud and nut are loose, or the special stud end does not protrude 1-1/2 to 2 threads beyond the nut, or all three punch marks are not visible, prior to further flight, remove aileron quadrant in accordance with Section 2. "Accomplishment Instructions," Paragraph B. "Removal/Installation" in BAe Mandatory S/B No. 27-JM-5257, dated June 6, 1986, and check the security of the nut P/N A103-JT securing the special stud P/N 13705E29 to the quadrant, and determine that peening of the stud is in accordance with the above BAe Service Bulletin. (i) If security and locking are satisfactory, prior to further flight, reinstall aileron control quadrant using steps (13) to (20) inclusive of the above Service Bulletin, and no further action is required. (ii) If the securing nut P/N A103-JT or special stud P/N 13705E29 is loose or the peening of the stud is not in accordance with the above BAe Service Bulletin, prior to further flight, remove and replace nut BAe P/N A103-JT with new nut BAe P/N RMTE 9868-6, install new stud BAe P/N 13705E91 and add split pin SP90-C7 to lock the nut on, according to the instructions in BAe Mandatory S/B 27-JM-5257, dated June 6, 1986. (b) Airplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished. (c) An equivalent means of compliance with this AD may be used if approved by the Manager, Aircraft Certification Staff, AEU-100, Europe, Africa and Middle East Office, FAA, c/o American Embassy, B-1000 Brussels, Belgium.
