Required as indicated, unless accomplished previously. To detect and correct corrosion on the seat rails for the passenger seats, which could result in the reduced structural integrity of the passenger seats, detachment of the seats from the seat rails, and injury to passengers, accomplish the following: Inspection and Corrective Actions (a) Within 1 year after the effective date of this AD, do a detailed inspection of the seat rails located in the passenger cabin, two above and two below the floor panels, for evidence of damage (missing paint from the frames or support angles) or corrosion, in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Service Bulletin J41-53-050, dated January 25, 2002. Note 1: For the purposes of this AD, a detailed inspection is defined as: “An intensive visual examination of a specific structural area, system, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at intensity deemed appropriate by the inspector. Inspection aids such as mirror, magnifying lenses, etc., may be used. Surface cleaning and elaborate access procedures may be required.” (1) If no damage (missing paint from the frames or support angles) or corrosion is found, repeat the detailed inspection thereafter at intervals not to exceed 2 years. (2) If any damage (missing paint from the frames or support angles) is found, before further flight, re-protect the area per the Accomplishment Instructions of the service bulletin. Repeat the detailed inspection thereafter at intervals not to exceed 2 years.

Repeat the detailed inspection thereafter at intervals not to exceed 2 years.
