The safety of aircraft has always been a top priority within the aviation industry. With advancements in technology and engineering, efforts to improve safety have become more focused and effective, particularly in the area of fuel tank flammability reduction (FTFR). In this article, we will discuss the crucial role patented technology plays in enhancing aviation safety, with a particular emphasis on FTFR and its related regulatory requirements.
The Challenge of Fuel Tank Explosions
Fuel tank explosions present a significant safety risk in aviation. Explosions typically occur in the ullage – the space above the fuel level that can create a dangerous mixture of fuel and air. When an ignition source, such as a spark, is present, the vapor adjacent to the spark ignites rapidly, creating a chain reaction that leads to a fuel tank explosion in milliseconds.
Regulatory Requirements for Fuel Tank Flammability Reduction
To address the risks associated with fuel tank explosions, the Federal Aviation Administration (FAA) has issued a series of airworthiness directives (ADs) related to fuel tank flammability compliance. These ADs require that all aircraft must meet the requirements of Federal Aviation Regulations FAR 25.981 and FAR 121.1117.
Additionally, aircraft must have fuel tanks and fuel systems that are designed, constructed, operated, and tested to meet the requirements of the applicable FARs. The ADs also mandate the inspection and maintenance of fuel tanks and fuel systems according to the requirements of FAR 121.1117. Lastly, aircraft must be tested to ensure they meet the requirements of FAR 25.981.
Jetaire's Solution: INVICTA™
Jetaire, a leading provider of fuel tank flammability reduction solutions, was the first company to develop an innovative solution to satisfy FTFR and FAR 25.981 through the development of INVICTA™. This proprietary technology utilizes a Reticulated Polyurethane Foam (RPF) that reduces the incidence of explosions.
The foam is a lightweight, self-extinguishing, three-dimensional skeletal matrix that suppresses fuel ignition caused by heated fuel vapor, tank rupture, lightning strikes, static discharge, or external factors.
Jetaire's INVICTA™ mitigates spark ignition within the center wing tank (CWT) of Boeing and Airbus aircraft and has been adopted by commercial and private aircraft operators of Boeing and Airbus aircraft in more than a dozen countries to date.
Compliance with Airworthiness Directives
To ensure compliance with the applicable airworthiness directives and mandates, Jetaire offers their INVICTA™ solution for various aircraft models. The FAA has issued multiple ADs corresponding to Jetaire's Supplemental Type Certificates (STCs) for different aircraft, including:
AD 2020-18-13 – Boeing 737 aircraft & corresponding Jetaire STC: ST03450NY
AD 2019-24-01 – Airbus A320 & 330 family aircraft & corresponding Jetaire STC: ST03834NY
AD 2020-18-16 – Boeing 767 aircraft & corresponding Jetaire STC: ST04405AT
AD 2019-24-01 - Airbus A330-200 aircraft & corresponding Jetaire STC: ST04590AT
AD 2016-07-07 – Original AD on Boeing 757 aircraft & corresponding Jetaire STC: ST04415AT
The Benefits of INVICTA™
Achieving fuel tank flammability compliance is a complex process, but it is possible with the right knowledge and resources. Jetaire Group specializes in fuel tank flammability compliance and can help ensure compliance with the applicable airworthiness directives and mandates through their proprietary and patented INVICTA™ solution.
Installing INVICTA™ is straightforward and can be performed in only a matter of days. With the entire modification taking less than a week from start to finish and requiring zero maintenance after installation, INVICTA™ is not only the most effective FRM solution, but it is also the most efficient.
Conclusion
As the aviation industry continues to evolve and grow, the importance of trusted, proven technology in enhancing safety cannot be overstated. Fuel tank flammability reduction is just one area where innovative solutions, like Jetaire's INVICTA™, are making a significant impact on aviation safety. By ensuring compliance with airworthiness directives and leveraging cutting-edge technology, the aviation industry can continue to improve safety and protect both passengers and crew.
