Analyzed Economic Effects
2 provisions identified: 1 benefits, 1 costs, 0 mixed.
Mandatory bolt replacement on PC-24
If you own or operate a Pilatus Model PC-24 airplane, the FAA requires you to replace affected short rudder-trim control rod assemblies that use titanium threaded bolts with serviceable assemblies that have threaded steel bolts. This rule also supersedes AD 2023-26-05 and requires you to stop installing the affected titanium parts.
Fix addresses bolt fatigue safety risk
The FAA says some batches of the titanium bolts had microstructure variations that could affect fatigue and create an unsafe condition. Replacing the titanium bolts with steel ones and banning the affected parts is intended to address that safety risk for Pilatus PC-24 airplanes.
