Unsafe Condition

The unsafe condition is the potential for icing-related incidents or accidents due to pilot error when pilots-in-command (PIC) of MU-2B series airplanes lack proficiency in recognizing adverse operating conditions and safely operating in icing conditions.

AI-generated summary from the source AD text. Verify against the official source before acting.

Required Actions

Revise the Airplane Flight Manual (AFM) Limitations Section to require pilot training before flight into known or forecast icing conditions. The AFM must state that on or after June 15, 2004, no person may serve as PIC in such flights without completing the required Icing Awareness Training.

AGENCY:
 
Federal Aviation Administration (FAA), DOT.


ACTION:
 
Final rule; correction.


–––––––––––––––––––––––––––––––––––


SUMMARY:
 
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 June 15, 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.


DATES:
 
This AD becomes effective on April 16, 2004.

SUPPLEMENTARY INFORMATION:


Discussion


Has FAA taken any action to this point?
 
Analysis that the training level of the pilots-in-


command (PIC) of the MU-2B series airplanes made it difficult for them to recognize adverse


operating conditions and operate safely while flying in icing conditions caused FAA to issue AD 97-


20-14, Amendment 39-10150, and AD 2003-22-07, Amendment 39-13355.


AD 97-20-14 required incorporating information into the Limitations Section of the Airplane


Flight Manual (AFM) that requires pilot training before further flight into known or forecast icing


conditions after a certain date.


AD 2003-22-07 also requires incorporating information into the Limitations Section of the


Airplane Flight Manual (AFM) that requires pilot training before further flight into known or forecast


icing conditions after a certain date based on a new training video developed by Mitsubishi.


What has happened since AD 2003-22-07 to initiate this action?
 
We incorrectly stated in the


AFM Limitation 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.


Stating on or before June 15, 2004, means that after June 15, 2004, there is no longer a


requirement to get the IAT training. This was not the intent of the FAA or Mitsubishi.


The correct statement in the AFM Limitation should be that on or after June 15, 2004, 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.


What is the potential impact if FAA took no action?
 
If the language in the AFM Limitation


Section is not corrected, no one would be required to have the mandatory pilot IAT training after


June 15, 2004. Lack of mandatory pilot IAT training could result in an increased chance of icing-


related incidents or accidents of the MU-2B series airplanes due to pilot error.


FAA's Determination and Requirements of the AD


What has FAA decided?
 
We have evaluated all pertinent information and identified an unsafe


condition that is likely to exist or develop on other products of this same type design.


Since the unsafe condition described previously is likely to exist or develop in Mitsubishi MU-


2B series airplanes when the PIC is not proficient in the operating conditions of these airplanes, we


are issuing this AD to decrease the chance of icing-related incidents or accidents of the MU-2B series


airplanes due to pilot error.


What does this AD require?
 
This AD requires you to incorporate information into the


Limitations Section of the Airplane Flight Manual (AFM) that requires pilot training before further


flight into known or forecast icing conditions after a certain date. That AFM limitation consists of the


following:
