NOTE 5. This Type Certificate (TC) has been designated "ABANDONED". A “Notice of Intent To Designate as
Abandoned Certain Type Certificates Issued in the Restricted Category,” was published by the Federal
Aviation Administration (FAA) in the Federal Register on August 8, 2003 (68 FR 47379). That Notice listed
this TC. The FAA received no comments on the published Notice. The FAA has been unable to contact this
TC holder. Hence, the FAA has determined that this TC holder is not complying with its Continued
Operational Safety (COS) responsibilities. Therefore, no additional aircraft will be added to this TC and no
additional original airworthiness certificates will be issued based on this TC. The effectiveness of this TC is
limited to those aircraft that received original airworthiness certification prior to the incorporation of this
note (Date of Incorporation, January 24, 2005). Subsequently, if the TC holder is located and assumes their
COS responsibilities, the restriction(s) imposed by this note may be lifted.
