EASA AD 2022-0158
SUPERSEDED BY EASA AD 2022-0245
Summary
EASA Airworthiness Directive 2022-0158 addresses corrosion issues found on the main and nose landing gear electro-mechanical actuators of Pilatus PC-12/47E aeroplanes, specifically those with manufacturer serial numbers 1300, 1451, and subsequent. The directive mandates replacement of affected landing gear actuators to prevent potential failure. It applies to parts with specific part numbers and provides definitions for affected and serviceable parts.
What Changed
This directive introduces mandatory replacement of certain main and nose landing gear actuators on affected PC-12/47E aircraft to mitigate corrosion risks. It requires operators to replace affected parts with serviceable ones within specified compliance times based on corrosion environment severity. The AD also allows installation of only serviceable parts from the effective date onward.
Why It Matters
This AD is critical for maintaining the structural integrity and safe operation of the landing gear on affected Pilatus PC-12/47E aircraft. Corrosion-induced cracks could lead to actuator failure, unintended landing gear extension, and potential damage or injury. Compliance ensures continued airworthiness and prevents costly repairs or safety incidents.
What To Do
Operators of Group 1 PC-12/47E aeroplanes must replace affected landing gear actuators within three months if operating in moderate or severe corrosion environments, or within six months, 300 flight hours, or the next scheduled 12-month inspection if in mild corrosion environments. From the effective date, only serviceable parts may be installed on any PC-12/47E aircraft. Compliance with Pilatus Service Bulletin 32-030 is required.
