Background

    The FAA is posting this notice to inform the public of the intent 
to designate as abandoned Horizon Instruments, Inc., STC No. SA5842NW 
for the installation of an engine electronic digital tachometer, 
Horizon Model P-1000, P/N P100070-, in Piper Aircraft PA-28-140, -150, 
-151, -160, -161, -180, -181, -235, -236, -201T, R-180, R-200, R-201, 
R-201T, RT-201, RT201T, and S-160 series airplanes, and subsequently 
release the related engineering data.
    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 
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 three 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 three years.
    On June 9, 2023, the FAA sent a registered letter to Horizon 
Instruments, Inc., at its last known address, 600 S. Jefferson St., 
Unit C, Placentia, CA 92870. The letter was returned, unable to be 
forwarded. The letter informed Horizon Instruments, Inc., that the FAA 
had received a request for engineering data related to STC No. SA5842NW 
and was conducting a due diligence search to determine whether the STC 
was inactive and may be considered abandoned. The letter further 
requested Horizon Instruments, Inc., to respond in writing within 60 
days and state whether it is the holder of the STC. The FAA also 
attempted to make contact with Horizon Instruments, Inc., by other 
means, including telephone communication and emails, without success.

Information Requested

    If you are the owner or heir or a transferee of STC No. SA5842NW or 
have any knowledge regarding who may now hold STC No. SA5842NW, please 
contact Chuck Ayala 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 STC No. SA5842NW, you must provide a notarized 
copy of your government-issued identification with a letter and 
background establishing your ownership of the STC and, if applicable, 
your relationship as the heir to the deceased holder of the STC.

Conclusion

    If the FAA does not receive any response by January 24, 2024, the 
FAA will consider STC No. SA5842NW 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.
