Aviation Leaders Warn of Supply Chain Weaponization at Changi Summit

Aviation leaders and regulators convened at the Changi Aviation Summit in Singapore on February 2, 2026, to address growth barriers and geopolitical volatility. Willie Walsh, Director General of the International Air Transport Association (IATA), reported that ongoing supply chain disruptions continue to heavily impact global airlines, specifically affecting planemakers Airbus and Boeing and engine manufacturers GE Aerospace and Pratt & Whitney. Walsh noted that geopolitical shifts and U.S. import tariffs have disrupted air cargo more than passenger services, contributing to a 0.8 percent decline in shipments between Asia and North America last year.

EU Transport Commissioner Apostolos Tzitzikostas warned against the "weaponisation" of supply chain dependencies, specifically highlighting the industry's reliance on China for rare earth metals essential for jet engines. Meanwhile, Toshiyuki Onuma of the International Civil Aviation Organization (ICAO) called for a systemic transformation to support projected passenger growth and achieve net-zero carbon emissions by 2050.

The summit took place amid concerns that aircraft certification is being politicized. U.S. President Donald Trump demanded that Canada certify specific U.S.-designed Gulfstream business jets or face tariffs. Critics argue this pressure entangles technical certification in politics and potentially violates the Chicago Convention, a global aviation treaty.
