<HD SOURCE="HD1">Background</HD>
The FAA is posting this notice to inform the public that the FAA intends to designate as abandoned John Benham STC No. SA3866SW and subsequently release the related engineering data. John Benham STC No. SA3866SW is for a modified door latch, in Cessna Aircraft Model 170, 170A, and 170B airplanes.
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 49 U.S.C. 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 10, 2025, the FAA sent a registered letter to John Benham at his last known address: 659 Madrona Road, Pipe Creek, TX 78063. The letter was returned, unable to be forwarded. The letter informed John Benham that the FAA had received a request for engineering data related to STC No. SA3866SW and was conducting a due diligence search to determine whether the STC was inactive and may be considered abandoned. The letter further requested John Benham to respond in writing within 60 days and state whether he is the holder of the STC.
<HD SOURCE="HD1">Information Requested</HD>
If you are the owner or heir or a transferee of STC No. SA3866SW or have any knowledge regarding who may now hold STC No. SA3866SW, please contact JoAnn Murphy as described in this notice under
<E T="02">FOR FURTHER INFORMATION CONTACT</E>
or using a method described under
<E T="02">ADDRESSES</E>
. If you are the heir of the owner, or the owner by transfer, of STC No. SA3866SW, 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.
<HD SOURCE="HD1">Conclusion</HD>
If the FAA does not receive any response by February 17, 2026, the FAA will consider STC No. SA3866SW 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.
