[Docket No. 97-CE-21-AD; Amendment 39-11819; AD 2000-09-15 R1]
RIN 2120-AA64


Airworthiness Directives; Mitsubishi Heavy Industries, Ltd., MU-
2B Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: This amendment clarifies information contained in 
Airworthiness Directive (AD) 2000-09-15, which currently requires you 
to incorporate modifications to the airplane operating systems on all 
Mitsubishi Heavy Industries, Ltd. (Mitsubishi) MU-2B series airplanes. 
The Federal Aviation Administration (FAA) inadvertently omitted service 
information from the AD that is needed to accomplish these 
modifications on some of the affected airplanes. This document retains 
the requirements of AD 2000-09-15, and adds the service information to 
the AD. The actions specified in this AD are intended to continue to 
assist in preventing departure from controlled flight while operating 
in icing conditions.

DATES: The effective date of this AD is July 24, 2000.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications as of July 24, 2000.

ADDRESSES: You may get the service information referenced in this AD 
from Mitsubishi Heavy Industries America, Inc., 15303 Dallas Parkway, 
suite 685, LB-77, Addison, Texas 75001-4692; telephone: (972) 980-5001, 
facsimile: (972) 980-5091. You may examine this information at FAA, 
Central Region, Office of the Regional Counsel, Attention: Rules Docket 
No. 97-CE-21-AD, 901 Locust, Room 506, Kansas City, Missouri 64106; or

SUPPLEMENTARY INFORMATION:   

Discussion

Has FAA Taken Any Action to This Point?

    Several icing-related incidents and accidents of MU-2B series 
airplanes and FAA's investigation of both the airplane design and 
pilot's ability to operate in icing conditions caused FAA to issue AD 
2000-09-15, Amendment 39-11724 (65 FR 30865, May 15, 2000). This AD 
requires you to incorporate the following airplane operating systems:

--a deice monitoring system;
--an automatic autopilot disconnect system; and
--a trim-in-motion alert system.

What Has Happened Since AD 2000-09-15 To Initiate This Action?

    The FAA inadvertently omitted service information from the AD that 
is needed to accomplish these modifications on some of the affected 
airplanes.
    Consequently, we see a need to clarify AD 2000-09-15 to assure that 
the modifications can be fully carried out.

Correction of Publication

    This document clarifies the intent of the airplane operating system 
modifications by incorporating additional service information that is 
needed to accomplish the actions of AD 2000-09-15 on Mitsubishi MU-2B 
series airplanes. This document also adds the amendment to Sec. 39.13 
of the Federal Aviation Regulations (14 CFR 39.13).
    Since this action only clarifies the intent of the Mitsubishi MU-2B 
series airplane operating system modifications, it has no adverse 
economic impact and imposes no additional burden on any person than 
would have been necessary to accomplish the AD as currently written. 
Therefore, FAA has determined that prior notice and opportunity for 
public comment are unnecessary.
