Background
The FAA is posting this notice to inform the public that the FAA
intends to designate as abandoned Stephen M. Hill STC No. SA1584SW and
subsequently release the related engineering data. Stephen M. Hill STC
No. SA1584SW is for single and dual camera installations, navigation
sight installations, drop port installation, and emergency exit and
door optical glass installations for oblique cameras in Gulfstream
American Model 680FL(P), 680T, 680V, 680W, 681, 690, 680F(Press), 690A,
685, 690B, 690C, and 695 airplanes.
[[Page 59321]]
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 April 18, 2025, the FAA sent a certified letter to Stephen M.
Hill at his last known addresses: 151 Chase Street, Florence, SC 29501
and 1300 Pickney Avenue, Florence, SC 29501. The letter informed
Stephen M. Hill that the FAA had received a request for engineering
data related to STC No. SA1584SW and was conducting a due diligence
search to determine whether the STC was inactive and may be considered
abandoned. The letter further requested Mr. Stephen M. Hill to respond
in writing within 60 days and state whether he is the holder of the
STC. The FAA also attempted to contact Stephen M. Hill by other means,
including telephone communication, email, registered mail, etc.,
without success.
Information Requested
If you are the owner or heir or a transferee of STC No. SA1584SW or
have any knowledge regarding who may now hold STC No. SA1584SW, please
contact Richard Bolden 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. SA1584SW, 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 June 16, 2026, the FAA
will consider STC No. SA1584SW 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.
Issued on December 16, 2025.

Acting Deputy Director, Compliance & Airworthiness Division, Aircraft
Certification Service.
