South Korea suspended Apache helicopter flights.
The South Korean military has temporarily grounded 36 AH-64E attack helicopters since early October. The reason is the tests that the American authorities started due to a possible defect in the transmission. At the same time, the helicopters remain ready for immediate combat flight in case of emergency.
Boeing's Apache helicopters are South Korea's main attack asset. The US military also grounded the Apache last month during technical reviews following a crash in Texas in August that killed two US service members.
Other operators appear to be taking similar steps. Taiwan also reportedly grounded its Apache flights last month. Seoul said the helicopters would gradually return to service, based on the results of the tests.
