data. STC No. SA91NW is for the installation of a strobe light
flashtube system installation, on Univair Aircraft Corporation
(Stinson) Model 108-3 airplanes. STC No. SA152NW is for the
installation of a deck and glare shield (with and without instrument
lights), on Textron Aviation Inc. (type certificate formerly held by
Cessna Aircraft Company) Model 170, 170A, 170B, 172, 172A, 180, 180A,
180B, 180C, 180D, 180E, 180F, 180G, 182, 182A, 182B, 182C, 182D, 182E,
182F, 182G, 182H, 182J, 182K, 182L, 182M, 182N, 182P, 185, 185A, 185B,
and 185C airplanes; Textron Aviation Inc. (type certificate formerly

M20C, M20D, M20E, M20F, and M20G airplanes. STC No. SA2472WE is for the
installation of a high intensity anti-collision light system, on
Textron Aviation Inc. Model 170, 170A, and 170B airplanes.
The FAA has received a third-party request for the release of the
engineering data for STC No. SA152NW 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
[[Page 3300]]
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 July 18, 2025, the FAA sent a certified letter to R.J. Schroers
at his last known address: 4479 139th Ave. SE, Bellevue, Washington
98006. The letter was returned, unclaimed, and unable to be forwarded.
The letter informed R.J. Schroers that the FAA had received a request
for engineering data related to STC No. SA152NW and was conducting a
due diligence search to determine whether the STC was inactive and may
be considered abandoned. The letter further requested that R.J.
Schroers respond in writing within 60 days and state whether he is the
holder of the STC. The FAA also attempted to make contact with R.J.
Schroers by other means, including telephone communication, without
success.
Information Requested
If you are the owner or heir or a transferee of STC No. SA91NW,
SA152NW, or SA2472WE or have any knowledge regarding who may now hold
STC No. SA91NW, SA152NW, or SA2472WE, please contact Ed Mills 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.
SA91NW, SA152NW, or SA2472WE, 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 July 27, 2026, the FAA
will consider STC Nos. SA91NW, SA152NW, and SA2472WE 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 January 22, 2026.

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