# SUPPLEMENTARY INFORMATION:

## Comments Invited

                    The FAA invites interested parties to provide comments, written data, views, or arguments relating to this notice. Send your comments to an address                           ( print page 58634)                        listed under the                     **ADDRESSES**                     section.

All comments received will be available in the docket for examination by interested persons.                

## Background

The FAA is posting this notice to inform the public of the intent to designate as abandoned STC No. SA1201GL, which authorized a gross weight increase for Aeronca Model 65-C and S-65-C 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 with this STC holder for more than three years.

On September 23, 2022, the FAA sent a registered letter to the STC holder, Lawrence F. Diedrich, at his last known address, Route 3, Box 279, Lodi, WI 53555. The letter informed Mr. Diedrich that the FAA had received a request for engineering data related to STC No. SA1201GL and was conducting a due diligence search to determine whether the STC was inactive and may be considered abandoned. The letter further requested Mr. Diedrich to respond in writing within 60 days and state whether he is the holder of the STC.

## Information Requested

                    If you are the owner or heir or a transferee of STC No. SA1201GL or have any knowledge regarding who may now hold STC No. SA1201GL, please contact JoWanna Jenkins 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. SA1201GL, 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 February 26, 2024, the FAA will consider STC No. SA1201GL 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 August 21, 2023.
