Compliance required as indicated, unless already accomplished.

To prevent reversal of the rudder feel function, within the next 500 hours' time in service after the effective date of this AD, accomplish the following:

  (a) Replace the paired links located in the rudder feel simulator linkage, Hobson P/N CH 504-071 or CH 504-280 with redesigned Hobson slotted links, P/N CH 504-446 in accordance with British Aircraft Corporation on BAC 1-11 Alert Service Bulletin PM 3290, or later ARB-approved issue, or an equivalent approved by the Chief, Aircraft Certification Staff, FAA, Europe, Africa, and Middle East Region.

  (b) Attach Hobson slotted links P/N CH 504-446 with bolts P/N CH 127803-25 (NAS 1108-25) and CH-127803-22 (NAS 1108-22), or self-retained bolt P/N CH 127800 (NAS 1108-27-SR) and rivet P/N CH 524-129-3. If bolts P/N CH127803-25 (NAS 1108-25) and CH 127803-22 (NAS 1108-22) are used, replace these bolts with self-retained bolt P/N CH 127800 (NAS 1108-27-SR) and rivet P/N CH-524-129-3 during the next overhaul of the rudder feel simulator units.
