EASA AD 2022-0212
Air Conditioning — Vapour Cycle Cooling System / Compressor Condenser Cables — Inspection / Modification
Summary
EASA Airworthiness Directive 2022-0212 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Pilatus PC-12, PC-12/45, PC-12/47, and PC-12/47E aeroplanes with specific manufacturer serial numbers. The directive addresses an unsafe condition related to the vapour cycle cooling system compressor/condenser cables and their grounding installation. It mandates inspection and modification to prevent potential fire hazards caused by insufficient grounding.
What Changed
EASA Airworthiness Directive 2022-0212 introduces a new requirement for a one-time inspection of the power return and chassis grounding cable attachment points at frame 37 on affected Pilatus PC-12 series aeroplanes. It also requires modification of the vapour cycle cooling system compressor/condenser cable installation by adding an isolated chassis ground cable. This directive is a new regulation and does not supersede any previous ADs.
Why It Matters
This directive is critical for aviation professionals because it addresses a potential fire risk due to insufficient grounding of the vapour cycle cooling system, which could cause severe damage to the aircraft and endanger safety. Operators and maintenance organizations must ensure compliance to maintain airworthiness and prevent in-flight incidents. Compliance teams need to track and enforce these inspections and modifications within the specified timeframe to avoid operational disruptions.
What To Do
Operators of affected Pilatus PC-12, PC-12/45, PC-12/47, and PC-12/47E aeroplanes must perform a one-time inspection of the power return and chassis grounding cable attachment points at frame 37 within two months from 1 November 2022. If discrepancies are found, corrective actions approved by Pilatus must be implemented before the next flight. Additionally, the vapour cycle cooling system compressor/condenser cable installation must be modified by installing an additional isolated chassis ground cable within the same two-month period.
