Operators of 171 Bombardier DHC-8-series aircraft in US registry must replace improperly manufactured tubes for an estimated overall cost of $1.52 million, according to the Federal Aviation Administration (FAA).

The tubes of various pushrods on all four DHC-8 models, including the -100, -200 and the Q300 and Q400, were heated improperly during manufacturing, the FAA says. If the components fail, the aircraft could lose rudder control or have a jammed nose landing gear door, the agency adds.

The FAA estimates replacement parts for each aircraft will cost $6,504 and consume about 28 work hours to complete.
