5.1 INTRODUCTION 

This section lists the Fuel System Limitations (FSL) that are mandated by the Special Federal Aviation Regulation (SFAR) 88. 

FSLs are limitation requirements that identify all the necessary maintenance and inspection instructions to maintain the design features required to preclude the existence or development of an ignition 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.
