The FAA needed more immediate checks than Boeing had suggested, which on Friday was said to have "been in the process of introducing safety and operation of vehicles throughout the ship."
The Federal Aviation Administration (FAA) said on Friday it was seeking U.S. operators of 143 Boeing Co 737 Classic aircraft to look into the possible failure of the cables as a result of an accident investigation in Indonesia in January. The 737 Classic is an older generation of aircraft over twenty years old.
The FAA said the issue affected 1,041 737-300, -400 and 500 Classic airlines worldwide, but many are currently not working, due to COVID-19 or other problems. The FAA is issuing a pilot operational guidance guide to ensure that the flap synchro wire, which plays a role in the operation of the aircraft system, is securely connected to the safety sensor.
Phone failure can be detected by the automated computer computer of the affected aircraft and may be a safety hazard. The FAA needs some quick checks than was suggested by Boeing, who said late Friday that it was "in an ongoing effort to introduce safety and operational improvements across the ship.
“The new 737 MAX and the new 737 NG are not affected by the director. The FAA and Boeing have identified a potential problem during an investigation into the Jan 9 crash of the Sriwijaya Air Flight 182 in the Indonesian capital. Indonesia's third major airplane crash in just over six years has shed light on a poor air safety record in a country in Southeast Asia.
All 62 aboard were killed after a 26-year-old Boeing Co 737-500 crashed into the Java Sea shortly after leaving Jakarta. The FAA said there was no evidence that the flap synchro wire issue played a role in the risk even though it was possible for the failed connection to raise security concerns that ensured immediate attention.
In February, Indonesia's National Transportation Safety Committee (KNKT) reported that the plane had an engine imbalance that eventually led to a sharp truck before sinking for the last time in the sea.
There have been two problems reported with the autothrottle system that automatically controls engine power based on feed logs, but the problem was fixed four days before the accident, the organization said.
Boeing released a message on March 30 to management directing them to perform automatic computer checks to ensure that the phone was connected within 250 hours of flight. The FAA requires a preliminary inspection within 250 hours of flight or two months from now, depending on what happens first, "to ensure that low-cost aircraft are used in a timely manner." Operators should adjust when needed.
The FAA said a faulty connection could lead to the failure of the auto-compressor system to detect the buttocks of aircraft if the aircraft engines were operating in various locations due to some malfunction.
The FAA requires a follow-up check every 2,000 hours after the flight. The affected workers in the US are Aloha Air Cargo, DHL, Aero Airways, Kalitta Charters and Northern Air Cargo, the FAA said.
