Boeing 737NG crack

After Boeing 737MAX series airliner suffered a “global grounding” in the first half of the year, its “predecessor” model has recently experienced new trouble. Late on Friday (27), the Federal Aviation Administration (FAA) announced that a small number of Boeing 737 “New Generation” (737NG) passenger planes were found to have cracks in the same key location, requiring airlines to conduct an investigation of some of the aircraft series and report immediately. Boeing confirmed on the same day that it had notified the shipping company using 737NG of the crack problem, but “there are no problems reported in operating passenger aircraft at present.” The FAA and Boeing did not reveal how many planes would be affected.
737NG is the third generation short and medium range narrow body jet developed by Boeing. It first flew in 1997, including 737-600, -700, -800 and-900 series. As of July 31 this year, a total of 7040 737NG were delivered, of which more than 5,000 are – 800 series. It is worth mentioning that 737NG’s successor is 737MAX, which suffered a “global grounding” in March this year due to two major aviation accidents in five months, and is still under investigation and assessment. KOMOnews, a Seattle news website, reported that earlier this month, a relatively new 737NG aircraft undergoing renovation was found to have a serious crack in the fuselage and wing connection.
