EASA AD 2021-0110-CN
CANCELLED: Landing Gear — Nose Landing Gear Fork Assembly — Inspection / Replacement
Summary
EASA Airworthiness Directive Cancellation Notice 2021-0110-CN is an official cancellation of the previous EASA AD 2021-0110 concerning the inspection and replacement of the nose landing gear fork assembly on Pilatus PC-12 series aeroplanes. This cancellation applies to all PC-12, PC-12/45, PC-12/47, and PC-12/47E aircraft with affected nose landing gear parts. The notice confirms that the previously identified corrosion issue on the nose landing gear fork assembly is no longer considered an unsafe condition requiring mandatory action.
What Changed
This document cancels EASA AD 2021-0110, which mandated a one-time inspection and possible replacement of the nose landing gear fork assembly due to corrosion concerns. New analysis and service feedback showed that the risk of failure due to hydrogen embrittlement does not exist, and Pilatus introduced a repair procedure with improved corrosion protection. Consequently, no further mandatory inspections or replacements are required under this cancellation notice.
Why It Matters
For aviation professionals, this cancellation means that operators and maintenance organizations no longer need to perform the previously required inspections or part replacements on the nose landing gear fork assembly of affected PC-12 aircraft. This reduces maintenance burden and associated costs while confirming the continued airworthiness of the fleet. Compliance teams can update their records to reflect that the unsafe condition has been resolved without further regulatory action.
What To Do
Affected operators and maintenance providers should note that no action is required following this cancellation notice. They should ensure their maintenance programs are updated to remove the inspection and replacement requirements from EASA AD 2021-0110. For technical questions, stakeholders may contact Pilatus Aircraft Ltd or EASA Safety Information Section as provided.
