    The FAA has received a third-party request for the release of the 
aforementioned engineering data under the provisions of the Freedom of 
Information Act (FOIA), 5 U.S.C. 552. The FAA cannot release commercial 
or financial information under FOIA without the permission of the data 
owner. However, in accordance with title 49 of the United States Code 
Sec.  44704(a)(5), the FAA can provide STC ``engineering data'' it 
possesses for STC maintenance or improvement, upon request, if the 
following conditions are met:
    1. The FAA determines the STC has been inactive for 3 years or 
more;
    2. Using due diligence, the FAA is unable to locate the owner of 
record or the owner of record's heir; and
    3. The availability of such data will enhance aviation safety.
    There has been no activity on this STC for more than 3 years.
    On December 17, 2025, the FAA sent a registered letter to Century 
Flight Systems, Inc., to its last known address: 3003 FM 1195, Mineral 
Wells, TX 76067-0610. The letter informed Century Flight Systems, Inc., 
that the FAA had received a request for engineering data related to STC 
No. SA3496SW-D and SA3497SW-D and was conducting a due diligence search 
to determine whether these STCs and 763 other STCs were inactive and 
may be considered abandoned. The letter further requested that the 
company respond in writing within 60 days and state whether it is the 
holder of these 765 STCs. The FAA has also attempted to make contact 
with Century Flight Systems, Inc., by other means, including telephone 
communication and emails, but without success.

Information Requested

    If you are the owner or heir or a transferee of all the 765 STCs or 
have any knowledge regarding who may now hold any of these STCs, please 
contact Aourolia Kristianti using a method described in this notice 
under FOR FURTHER INFORMATION CONTACT. If you are the heir of the 
owner, or the owner by transfer of any of these STCs, you must provide 
a notarized copy of your government-issued identification with a letter 
and background establishing your ownership of any of the STCs and, if 
applicable, your relationship as the heir to the deceased holder of the 
STCs.

Conclusion

    If the FAA does not receive any response by September 15, 2026, the 
FAA will consider all 765 STCs as abandoned, and the FAA will proceed 
with the release of the requested data. This action is for the purpose 
of maintaining the airworthiness of an aircraft and enhancing aviation 
safety.
