QUESTIONS & ANSWERS
The Switlik AV-35H stands out for its independent twin-cell inflation system, which offers enhanced redundancy and safety during emergency use. Unlike single-cell vests, each inflation cell operates independently, providing additional buoyancy security in case one side is compromised. It’s also FAA-approved under TSO-C13f and TSO-C13d, making it compliant for use with major air carriers worldwide.
“TBO” stands for Time Between Overhaul, and this Switlik AV-35H life vest is sold with a recommended 5-year TBO. This means the vest should be inspected, tested, repaired (as needed), and recertified by an Authorized Service Center in accordance with the latest revision of the CMM, every five years from the date of manufacture. Following the specified TBO helps support compliance and simplifies long-term maintenance planning.
Yes, the AV-35H offers multiple donning configurations, making it adaptable for a wide variety of aircraft seat layouts and passenger profiles. Airlines can choose different packaging styles and stowage options that suit their seat stowage compartments. This customization ensures the vest is easy to store, deploy, and use across diverse fleet types.
The AV-35H is designed for quick, intuitive donning, even under stress. Its simple strap and buckle configuration enables passengers to put it on correctly without confusion. The vest’s high-visibility design and independent inflation cells further simplify its usability in low-light or emergency conditions.
With proper maintenance, the AV-35H offers a service life of up to five years, based on this particular model’s TBO interval. Its heat-sealed construction, rugged materials, and corrosion-resistant hardware are designed for long-term use in airline environments. Routine checks and periodic overhauls ensure it remains compliant and ready for emergency deployment.
Absolutely! In addition to FAA approval, the AV-35H is accepted by international aviation authorities such as the UK CAA, Japan JCAB, and others. This makes it an excellent choice for global commercial carriers operating across diverse regulatory jurisdictions.
The AV-35H uses a dual independent CO₂ inflation system, which increases reliability and safety. Each of the two air cells inflates separately, providing redundancy in the event of a malfunction in one system. The inflation system is corrosion-resistant and easy to service during scheduled maintenance intervals.
