Very simple story. Aussie based company Structural Monitoring Systems (SMN AX) has the only approved crack detection product in the market.
The 5 Qantas Boeing 737 NG planes (and dozens like it around the world) could have had far earlier detection with SMN’s CVM technology. To cut a long story short, CVM technology has vacuum channels, which if broken (via cracks emerging) notifies the ground crew of the structural issue.
The company already has a contract with Delta Airlines for its aircraft. This type of technology not only has the potential to ward off catastrophic failures but reduce the cost of inspections for airlines.
CM has owned SMN for over a decade. This trend was always coming.
