EASA AD TCD-4753B-2020
AFM Limitations Change - Pilot Training - Icing Conditions
Summary
Japan Civil Aviation Bureau Airworthiness Directive No. TCD-4753B-2020 mandates new pilot training requirements for Mitsubishi Model MU-2B and MU-2B-30 series airplanes when operating in known or forecast icing conditions. This directive updates the Airplane Flight Manual (AFM) Limitations Section to require pilots-in-command to have completed specific Mitsubishi Icing Awareness Training. The directive aims to enhance flight safety by reducing icing-related incidents caused by pilot error.
What Changed
This airworthiness directive introduces a mandatory update to the AFM Limitations Section requiring pilots to complete Mitsubishi Icing Awareness Training within 24 months before any flight into known or forecast icing conditions. It replaces the previous AD No. TCD-4753A-2004 and provides an alternative compliance method subject to JCAB approval. The training is provided free of charge by Mitsubishi Heavy Industries.
Why It Matters
This directive is critical for operators and compliance teams as it directly addresses pilot preparedness for icing conditions, a known safety risk for the affected Mitsubishi MU-2B series airplanes. Ensuring pilots have up-to-date training reduces the likelihood of icing-related accidents, thereby improving operational safety and regulatory compliance. Maintenance and support organizations must also be aware of these changes to assist operators in meeting the new requirements.
What To Do
Operators of Mitsubishi MU-2B and MU-2B-30 series airplanes must update the AFM Limitations Section by June 20, 2020, to include the new training requirement. Pilots intending to fly into known or forecast icing conditions must complete the Mitsubishi Icing Awareness Training within 24 months prior to the flight. For scheduling training, contact Mitsubishi Heavy Industries America, Inc. Aircraft Product Support Division at +1-972-934-5480. Alternative compliance methods require JCAB approval.
