REASON FOR REVISION This revision is sent to add some wire bundle W8173 clamp locations in the left wing rear spar that need Teflon sleeve installation. Also, some discrepancies in the compliance data, and in the Accomplishment Instructions and Figure group applicability data are corrected. Airplanes WF022-WF023, WF036-WF041, WF065-WF066, WF115-WF116, WF132-WF133, WF138-WF139, WF156-WF159, WF166-WF170 are added to a new Group 44, and airplanes WC587, WC593-WC595 are added to a new Group 45 of this service bulletin effectivity. These airplanes need to do a detailed inspection of the selected wire bundle clamps in the front spar bulkhead, to make sure that Teflon sleeve is installed.
These sections were changed:
1. In Summary, Planning Information, Material Information, Accomplishment Instructions and all applicable figures, changed the applicability data to add the new group and group configurations.
2. In Summary, Action, and Paragraph 1.D., Description, added Work Packages 17 thru 21.
3. In Summary, Compliance and Paragraph 1.E., Compliance, changed the FAA and Boeing compliance data.
4. In Summary, Background, Summary Evaluation Table, changed the Kits/Parts required data.
5. In Paragraph 1.A., Effectivity, added new Groups 44 and 45.
