The Federal Aviation Administration (FAA) has issued a final rule for certain Airbus SAS airplanes due to an error found in the maintenance manual. The document reports that an incorrect torque value for the nuts attaching a pitot probe could lead to faulty readings affecting airplane navigation. As a result, re-torqueing of these nuts is required, and the use of the erroneous manual task is prohibited. The rule, which impacts 112 airplanes within the U.S., becomes effective on January 29, 2021, and comments on the rule are welcome until March 1, 2021.
Simple Explanation
The FAA found a mistake in the instructions for fixing a part on some Airbus airplanes, which could cause navigation problems, so they want to fix it by tightening some nuts correctly and stopping using the wrong instructions.
