What to do
Operators of ATR 72-101, -102, -201, -202, -211, -212, and -212A aeroplanes must identify if affected main landing gear hinge pins with part numbers D61000 or D60999 and listed serial numbers are installed. For aeroplanes with affected parts, replacement with serviceable parts must be completed within 12 months from 19 May 2020. Installation of affected parts is prohibited from the effective date, and alternative compliance methods such as replacing the entire landing gear with one containing serviceable parts are acceptable.
Summary
EASA Airworthiness Directive 2020-0101 is issued for ATR 72 series aeroplanes, specifically models ATR 72-101, -102, -201, -202, -211, -212, and -212A. It addresses the replacement of main landing gear hinge pins with part numbers D61000 and D60999 that have been identified as potentially thermally abused during production. This directive mandates the replacement of affected hinge pins to ensure continued airworthiness and prevent structural failure of the main landing gear.
What changed
EASA Airworthiness Directive 2020-0101 introduces a requirement to replace specific batches of main landing gear hinge pins on ATR 72 aeroplanes that were found to have been subjected to thermal abuse during manufacturing. It identifies additional serial number batches of pins suspected to be affected and mandates replacement within 12 months of the effective date. The directive also prohibits installation of affected parts on any aeroplane from the effective date onward.
Why it matters
This directive is critical for aviation professionals because it addresses a safety risk involving potential structural failure of the main landing gear, which could lead to gear collapse and possible injury or damage. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and avoid operational disruptions. Compliance teams need to track affected parts and ensure timely replacement to meet regulatory requirements.
