ST Engineering gains AML-STC for ACA system on Airbus platforms


ST Engineering’s Commercial Aerospace business has been granted an Approved Model List Supplemental Type Certificate (AML-STC) by the FAA, covering the installation of Aviation Clean Air (ACA)’s cabin air purification solution on Airbus platforms.

It means ST Engineering can install the patented Needlepoint Bipolar Ionisation (NPBI) system, which is designed to neutralise pathogens and purify air in flight, on commercial and VIP Airbus A320/A321 aircraft.

“With more borders opening up, we want to help boost passenger safety and confidence, and enhance passenger comfort with innovative cabin interior sanitisation solutions,” said Tan Yen Ping, vice president and head, cabin interior and engineering solutions, ST Engineering. “By combining our MRO and engineering expertise with ACA’s patented purification system, we aim to provide this proven and low-maintenance solution to support the return to flying.”

“ST Engineering is well-known and respected for its innovation and engineering capabilities,” said Howard Hackney, ACA managing member. “Their proven MRO expertise in serving airlines worldwide enhances ACA’s distribution network and allows more operators to experience the benefits of our system.”

ACA’s air ionisation and purification system is powered by the patented NPBI process, which is designed to purify the air and surfaces as well as neutralise viruses and bacteria throughout an aircraft interior. ACA reports that the system stops the spread of up to 99.9% of airborne and surface pathogens, including the SARS-CoV-2 virus. It added that the NPBI process can also remove odours, dust and pollen; prevent mould; neutralise common industrial gases; and reduce static electricity.

The system is automatically activated during flights to provide constant decontamination of the aircraft interior without using or introducing chemicals.
