Date 16 FEB 2011. Signed. FILING INSTRUCTIONS: In the Maintenance Program Manual (PSM 1-83-7) Part 2 Airworthiness Limitations, remove the Tempo- rary Revision TR AWL 3-109 from the Section AWL 5 - Fuel System Limitations and insert this new Tempo- rary Revision. Record this Temporary Revision No. and the relevant information in the appropriate columns of the TEM- PORARY REVISIONS INDEX at the front of PART 2, PSM 1-83-7. REASON FOR ISSUE: Revises the Fuel Systems Limitations (FSL) as follows: - Removes references to Service Bulletins in the Applicability column, - Revises Modsums in the Applicability column, - Revises NOTE1 and deletes NOTE2 due to the release of Airworthiness Directive CF2007-32 which takes precedence. This Temporary Revision replaces TR AWL3-109. TR AWL 3-109 was issued previously to revise the FSL NOTE1 and NOTE2. Temporary Revision TRAWL 3 - 109 was replaced by TRAWL 3- 108. TRAWL 3- 108 was issued previous- ly to add the tasks FSL-17 and FSL-18 and to revise the FSL NOTE2. Temporary Revision TR AWL 3 - 108 was replaced by TRAWL 3 - 106. TRAWL 3- 106 was issued previous- ly to add the tasks FSL-02, FSL-05, FSL-06, and FSL-08 thru FSL- 16, and to revise the Introduction. Temporary Revision TR AWL 3-106 was replaced by TR AWL 3-104. TR AWL 3-104 was issued previous- ly to introduce the Fuel System Limitations into this manual as mandated by the Special Federal Aviation Regulation (SFAR) 88 and to add the task FSL-04. ACTION: Use the Critical Design Configurations Control Limitations as given in this Temporary Revision.

FUEL SYSTEM LIMITATIONS 5.1 INTRODUCTION This section lists the Fuel System Limitations (FSL) that are mandated by the Special Federal Avi- ation Regulation (SFAR) 88. FSLs are limitation requirements that identify all the necessary maintenance and inspection instruc- tions to maintain the design features required to preclude the existence or development of an igni- tion source within the fuel tank system throughout the operational life of the aircraft. 5.2 RULES APPLICABLE TO FUEL SYSTEM LIMITATIONS A. No person may operate an aircraft unless instructions for maintenance and inspection of the fuel tank system are incorporated into the operator's maintenance program. B. Task intervals are provided in both flight hours and calendar intervals. Tasks are to be performed at whichever interval occurs first. 5.3 PAGE FORMAT DESCRIPTION The Fuel System Limitations (FSL) are presented in the following format: FUEL SYSTEM LIMITATIONS (FSL) Task Number Applicability Task Description Interval B D A. Task Number: Task reference number. B. Applicability: "All" is for all aircraft. A Mod or Modsum may be listed to identify the FSL as it applies to the aircraft configuration. C. Task Description: Brief description of the task to be done. D. Interval: Calculated limiting interval.
