So-called airworthiness directives issued by civil aviation authorities are actually intended to ensure safety. However, the EASA made a serious calculation error in the case of the Airbus A321P2F. This has now led to the directive having to be withdrawn. The operators of converted Airbus A321P2F freighters should actually be obliged to carry out precise inspections of the fuselages. However, the EASA made a serious error in calculating the time frame. According to official information, the wrong formula was accidentally used. In order to rule out further confusion, the entire airworthiness directive has now been withdrawn without replacement. Studies carried out by Airbus and Elbe Flugzeugwerke also contributed to the decision. These have shown that the time frame for inspections differs only minimally from that for passenger aircraft due to the use of the aircraft as cargo aircraft. There is no need to adhere to such tight intervals as those originally ordered by the EASA. An airworthiness directive dated December 7, 2022, which has already been implemented, is therefore completely sufficient. The EASA originally saw things differently, because the AD of September 12, 2023 had ordered much stricter inspections of the A321P2F fuselages. The calculations had shown that cracks could possibly develop early when used as a freighter. However, an incorrect formula was mistakenly used in the calculations. It has now been shown that the risk of fatigue symptoms does not differ significantly from use as a passenger aircraft. The EASA has withdrawn the order.
