The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.\n\nSeats and Berths\n\nAD/SEATS/17\n\nAmdt 2\n\n  \nSICMA Passenger Seats \\- Seat Belt Attachment 12/2002\n\nApplicability: All SICMA AERO SEAT seats P/N 91xx, 93xx, 95xx, 96xx, 97xx, 98xx, 99xx, 9Axx, 9Bxx, 9Cxx listed in Annex 1 of SICMA AERO SEAT Service Bulletin (SB) 91-25-045, all serial numbers which have not incorporated terminating action in accordance with SICMA AERO SEAT SB 91-25-032 or SB 91-25-045.\n\nNote 1: Terminating action in accordance with the SB would be recorded on the change placard.\n\nNote 2: These seats are known to be fitted to, but not limited to, Airbus Industrie, Boeing, Fokker and Bombardier aeroplanes.\n\nRequirement: 1. If not already accomplished in accordance with SB 91-25-032 Part 1, check tighten the affected bolt onto the seat attachment by using a torque wrench as per instructions given in Part One of SICMA AERO SEAT Service Bulletin 91-25- 045.\n\n2.
