Diamond Planes Get Wired: FAA Fixes Emergency Locator Glitches
Published Date: 5/15/2026
Proposed Rule
Summary
If you own a Diamond Aircraft DA20-C1, listen up! The FAA found that some emergency locator transmitters might not work because of a missing wire. They want owners to check the connector and fix any problems ASAP to keep flights safe—comments on this plan are open until June 29, 2026, and the fix could save lives without breaking the bank.
Analyzed Economic Effects
3 provisions identified: 0 benefits, 3 costs, 0 mixed.
Mandatory ELT Connector Inspection
If you operate a Diamond Aircraft DA20-C1 with an Artex ELT 1000 installed, you must perform a continuity inspection of the ELT D-sub connector within 3 months after the AD's effective date. The inspection follows Diamond Aircraft Mandatory Service Bulletin DAC1-25-05, Rev. 1, dated July 19, 2024.
Fix Missing Jumper Wire If Found
If the inspection finds the jumper wire between D-sub pins 5 and 12 is missing, you must install the jumper wire per the service bulletin. The FAA estimates that installing the jumper wire takes 1 work-hour at $85 plus $3 for parts, totaling $88 per airplane for each repair needed.
U.S. Fleet and Estimated Total Cost
The FAA estimates this AD would affect 365 U.S.-registered DA20-C1 airplanes with an Artex ELT 1000. The agency estimates the inspection cost at $85 per airplane and the total cost on U.S. operators at $31,025; the FAA separately estimates $88 per airplane for any on-condition repair.

2026-13440, Enabling Supersonic Overland Flight
The FAA wants to let supersonic planes fly over land again by updating old rules that banned them because of loud sonic booms. Thanks to new tech that keeps booms quiet, this change will open the door for faster, cooler flights across the U.S., helping America lead the world in supersonic travel. People and companies interested in supersonic flight should share their thoughts by August 17, 2026.
2026-13126, Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility; Extension of Comment Period
The FAA is giving more time—until August 5, 2026—for people to share their thoughts on new rules that would limit drone flights near important fixed sites like power plants or airports. 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
The FAA is proposing new rules to keep drones away from certain important fixed sites like power plants or airports to keep everyone safe and secure. If you own or operate one of these sites, you can request a drone flight restriction zone to protect your property and people nearby. Comments are open until July 6, 2026, and these changes could affect drone pilots and site operators, but no big costs are expected.
2026-16750, Establishment of Class E Airspace; DeKalb, IL
This action proposes to establish Class E airspace at Northwestern Memorial Healthcare Heliport, DeKalb, IL. The FAA is proposing this action to support new instrument procedures and instrument flight rule (IFR) operations.
2026-16754, Agency Information Collection Activities: Requests for Comments; Clearance for Renewal of Information Collection: Privacy International Civil Aviation Organization (ICAO) Address
In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval for an information collection renewal. The collection involves an aircraft operator's request for a privacy ICAO address through a web-based application process. The information to be collected is necessary to qualify for the authorized use of the privacy ICAO address services and for monitoring to support continued airworthiness and enforcement activities.
2026-16705, Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines
The FAA proposes to adopt a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent XWB-75, XWB-79, XWB-79B, and XWB-84 engines. This proposed AD was prompted by reports of differential oil pressure measurements that were lower than expected on in-service engines. This proposed AD would require modification of the engine with an improved front bearing housing oil feed tube assembly. This proposed AD would also prohibit the installation of an affected front bearing housing oil feed tube assembly on any engine. The FAA is proposing this AD to address the unsafe condition on these products.
