On Sep 28th 2021 Germany's BFU reported the captain (49, ATPL, 11,980 hours total, 11,750 hours on type) was pilot monitoring, the first officer (29, CPL, 2,084 hours total, 109 hours on type) was pilot flying.
A post flight inspection revealed the mechanism to control the horizontal stabilizer trim was not connected via the relevant cog wheels, the chain and the chain joint/lock were found separated in the forward equipment compartment. Chain and joint did not show any kind of damage.
Prior to the flight there had been maintenance works including works at the horizontal stabilizer manual trim, which should be concluded with an appropriate test. The relevant maintenance work cards were stamped showing the works and tests were completed and checked.
The occurrence was rated a serious incident and is being investigated by the BFU.
