2003-22-07 R1: The FAA is revising Airworthiness Directive (AD) 2003-22-07, which applies to all Mitsubishi Heavy Industries, Ltd. (Mitsubishi) MU- 2B series airplanes. AD 2003-22-07 requires incorporating information into the Limitations Section of the Airplane Flight Manual (AFM) that requires pilot training before flight into known or forecast icing conditions after a certain date. AD 2003-22-07 resulted from the development of a new training video that includes information that is critical to safety of the MU-2B series airplanes. This AD revision is the result of the FAA incorrectly stating in the actions required by AD 2003-22-07 that on or before June 15, 2004 (the effective date of AD 2003-22-07), no person may serve as pilot-in-command (PIC) of a MU-2B series airplane in a flight into known or forecast icing conditions, unless the PIC has received the required training. Consequently, this AD will correct the actions required in AD 2003-22-07 to require those actions on or after June15, 2004. We are issuing this AD to ensure that the Icing Awareness Training (IAT) requirement continues after June 15, 2004, in order to decrease the chance of icing-related incidents or accidents of the MU-2B series airplanes due to pilot error.
