The directive issued on May 5 by EASA warns operators of Airbus A350-900 and -1000 aircraft to amend their applicable AFM (aircraft flight manual) and Minimum Equipment List due to a software problem that could lead to loss of elevator control.\"An occurrence was reported in which the PRIMary flight control computers (PRIMs) indicated that both elevator actuators were found to be defective.\" EASA also states that further investigations revealed that incorrect instructions were implemented with the introduction of the \"PRIM P13 standard\", which is part of the X13 Flight Control and Guidance System (FCGS) standard. Since the effective date for resolving the problem was immediately set for the following days, EASA also required operators to change their applicable AFM, which is subject to a temporary update and revision. The EASA directive also states that they must \"inform all flight crews and thereafter operate the aircraft accordingly\". Affected operators must also amend the Airbus A350 Minimum Master Equipment List (MMEL) accordingly. This directive is considered to be an interim action, which means that other actions may take place in the coming days. Interestingly, this is not the first software bug related to the Airbus A350. In July 2019, some models of the A350-900 had an aviation problem, which could be corrected with a software update, or even by turning the aircraft off and on at least once every 149 hours. Carrying out this rudimentary action would have prevented \"partial or total loss of some aviation systems or functions\".
