FAA proposes 737NG flight control software inspections and updates

The FAA intends to require airlines inspect flight control computers on more than 500 737NGs to address risks that aircraft might drift below the glideslope during landing. A proposed rule released Feb 26 targets aircraft with flight control computers equipped with “operational programme software” versions “P8.0” and “P9.0”. Affected flight control computers are made by Rockwell Collins, now Collins Aerospace. Boeing has already released a software update to address the issue, and the FAA’s order, if finalised, would give airlines 1 year to make the updates. “The FAA has received reports that during autopilot-coupled instrument landing system approaches, the airplane did not capture or track the glideslope correctly,” says the proposed rule. <br/>
