(A321Fs)Lufthansa Grounds Two Airbus Freighters After Cracks Discovered in Fuselages

[BlankBox]

After discovering a crack in their fuselages, Lufthansa Cargo recently grounded two Airbus A321 Freighters (A321Fs). This issue is a first for the aircraft type and has brought concerns related to the A321Fs' passenger-to-cargo conversion design.

I doubt very seriously it's 'nothing'. Usually, when you find the same cracks on an 11-year-old aircraft and an unrelated 15-year-old aircraft something is up.​​​​​​​

I wonder where exactly theses are cracking. The article states that it's where the permanent balast fixture is located.
The basalt is bolted to the floor structure just forward of the Aft Pressure Bulkhead so I can understand if something around that area is cracking.
