Thousands of Boeing 737 are under emergency inspection due to
valve problems. Because it may cause engine failure.
The Federal Aviation Administration (FAA) last week gave orders about an emergency inspection of about 2000 Boeing 737 aircrafts because of potential engine
valve problems. Because it could cause engine failures. The emergency airworthiness directive requires airlines and other aircraft owners and operators to check the
valves on all 737 NG and 737 classic models that have been grounded for 7 days or more, NPR reported on the 24th. Recently, regulators have received four reports of single engine failures on such aircraft due to air
check valve problems."The valve is vulnerable to corrosion due to the aircraft's low frequency of use during the pandemic of novel coronavirus - COVID-19."
Boeing said in a statement Boeing also said it would provide inspection and adjustment information if the owners of such aircraft found problems. However, the
valve problem has nothing to do with the Boeing 737 Max, which has been grounded.
According to the Yonhap news agency, South Korea's Ministry of Land And Transportation also issued an emergency order on July 25, requiring that the country's airlines should inspect its Boeing 737. At present, nine Korean Airlines operate 148 such aircrafts like that.
