FAA to Release 765 STC Engineering Data
The FAA intends to declare 765 Century Flight Systems Supplemental Type Certificates (STCs) abandoned and, if it receives no response by September 15, 2026, will release the related engineering data to anyone who asks. The FAA says these STCs have had no activity for 3 years and that sharing the data will enhance aviation safety under 49 U.S.C. 44704(a)(5).
Owners Must Prove STC Ownership to Reclaim
If you are the owner, heir, or transferee of any of the 765 STCs, you must contact the FAA and provide a notarized copy of government-issued ID plus written background establishing ownership or heirship to reclaim the STCs. The FAA sent a registered letter dated December 17, 2025 requesting a written response within 60 days and will consider no response by September 15, 2026 as abandonment.

This affects drone operators and facility owners who want to keep the skies safe and secure. No new costs yet, just extra time to weigh in and help shape the rules.
2026-08943, Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility

2026-16795, Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737 -300, -400, and -500 series airplanes. This proposed AD was prompted by reports of nuisance stick shaker activation while accelerating to cruise speed at the top of a climb due to frozen angle of airflow (AOA) sensor vanes. This proposed AD would require installing new external case heaters (ECHs) on the left and right AOA sensors, performing repetitive functional tests and applicable corrective actions, and accomplishing applicable concurrent actions. The FAA is proposing this AD to address the unsafe condition on these products.
