Fuel Tank IGNITION MITIGATION MEANS
For Boeing 737 NG Series - Supplemental Type Certificate No. ST02980NY
For Boeing 737 Classic Series - Supplemental Type Certificate No. ST03589NY

AerSafe™, a fuel tank ignition mitigation means developed by AerSale®, is one of the few Federal Aviation Administration (FAA) approved options currently available that complies with the Fuel Tank Flammability Reduction (FTFR) rule. The FTFR rule requires fuel tank ignition sources and flammability exposure to be reduced in fuel tanks that are most at risk.

With the FAA deadline fast approaching, Boeing 737 operators have two options: a flammability reduction means such as nitrogen inerting or an ignition mitigation means such as AerSafe. All affected passenger aircraft flying within or into the United States and operating under FAR Part 121 must be manufactured to meet the FTFR rule or be retrofitted by December 26, 2017 to avoid being grounded.

The AerSafe system limits the amount of available oxygen that can ignite fuel vapors and prevents sparks from initiating an explosion. It has been tested and developed to exact tolerances to fill the cavity of the Boeing 737 NG and Classic series center fuel tank. AerSafe comes as a complete prefabricated kit, and after initial installation, the system is virtually maintenance free. AerSafe provides an economical solution with no mechanical parts that can fail, time-change components to replace, or flight test requirements after installation. AerSafe also complies with the Notice of Proposed Rulemaking (NPRM) No. FAA-2016-6139.

INSTALLATION
AerSale can perform AerSafe installation at any hangar around the world and can also provide training for the installation. Installation can be done at the same time as a light maintenance check or overnight after the aircraft center tank is de-fueled. AerSafe does not require maintenance between heavy check visits or special tooling to remove and install the parts. Aircraft can be modified or de-modified without any structural changes.

AerSafe Installation Kit includes:
  • All required materials
  • Installation instructions
  • Aircraft Maintenance Manual supplement
  • Aircraft Flight Manual supplement
  • License to use AerSafe on a single aircraft by serial number

DEADLINE
All affected passenger aircraft operating under 14 CFR Parts 121, 125, and 129 must be manufactured to meet the FTFR rule, or be retrofitted by December 26, 2017. The FTFR rule is detailed in the FAA Advisory Circular 120-98A.
