FAA Orders Check on Diamond Plane Emergency Transmitters
Published Date: 8/4/2026
Rule
Summary
The FAA is adopting a new airworthiness directive (AD) for certain Diamond Aircraft Industries Inc. (DAI) Model DA20-C1 airplanes. This AD was prompted by a report of a certain emergency locator transmitter (ELT) not activating due to a missing jumper wire. This AD requires a continuity inspection of the D-sub connector of the Artex ELT 1000 and, if necessary, corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
Analyzed Economic Effects
3 provisions identified: 0 benefits, 3 costs, 0 mixed.
Mandatory ELT connector inspection
If your airplane is a Diamond Aircraft DA20-C1 with an Artex ELT 1000 installed, you must do a continuity inspection of the ELT D-sub connector within 3 months after September 8, 2026. The FAA estimates the inspection takes 1 work-hour at $85 and $0 parts, so the direct per-airplane inspection cost is $85.
Fix missing jumper wire if found
If the continuity inspection finds the jumper wire is missing between D-sub pins 5 and 12, you must install the jumper wire as the corrective action. The FAA estimates that installing the jumper wire takes 1 work-hour ($85) plus $3 in parts, for a total of $88 per repair.
FAA scope and national cost estimate
The FAA estimates this AD affects 365 DA20-C1 airplanes on the U.S. registry. At $85 per inspection, the FAA estimates total inspection costs to U.S. operators of $31,025; any required jumper-wire installs would cost about $88 per airplane.

2026-15585, Requirements for Interference-Tolerant Radio Altimeter Systems
In July 2025, President Trump signed the One Big Beautiful Bill Act. Section 40002 of that law re-institutes the Federal Communications Commission's general auction authority and specifically directs the Commission to complete a system of competitive bidding for not less than 100 megahertz in the 3.98-4.2 gigahertz band (Upper C- band). This final rule supports the Federal Communications Commission's July 2026 Report and Order that makes 160 megahertz of the Upper C-band available for terrestrial wireless flexible use via a system of competitive bidding. To ensure safe, efficient, and reliable aviation operations in the presence of wireless signals in the C-band, the Federal Aviation Administration is issuing new regulations that require all radio altimeters to meet specific minimum performance requirements. These new radio altimeters must withstand interference from wireless signals in neighboring spectrum bands and continue to provide accurate altitude readings to both pilots and integrated aircraft safety systems. These regulations require all aircraft equipped with radio altimeters operating under part 121 and those aircraft with radio altimeters operating under part 129 with 30 or more passenger seats or a payload capacity of more than 7,500 pounds to comply with the minimum performance requirements by December 30, 2030, which is prior to the date the Federal Communications Commission authorizes the use of the Upper C-band for new wireless services, as stated in its Report and Order. All other aircraft equipped with radio altimeters that are required to comply with part 91, including aircraft operating under parts 125, 133, 135, 136, 137, 194, and all other aircraft operating under part 129 that are not subject to the initial deadline, must comply with the same minimum performance requirements on or before October 31, 2034.
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.
2026-19171, Airworthiness Directives; Rolls-Royce Deutschland Ltd. & Co. KG Engines
The FAA is making a new rule for certain Rolls-Royce Deutschland engines because some oil pumps might cause low oil pressure. If your plane has two of these engines, you need to make sure only one has the affected oil pump to keep flying safe. This rule starts on September 21, 2026, and owners should act fast to avoid problems and keep their planes in the sky.
2026-19143, Amendment of Class E Airspace; Alma, MI
The FAA is updating the Class E airspace around Alma, Michigan because a nearby navigation beacon was turned off. This change helps keep flights safe and smooth for pilots using instruments to fly. The new airspace rules kick in on December 24, 2026, with no extra costs for anyone.

This final rule modernizes the Materials of Trade (MOT) exception in the Hazardous Materials Regulations (HMR) by increasing the maximum allowable quantities of lithium batteries that can be transported as MOTs. This increase removes an undue regulatory burden which constrains the ability of construction, landscaping, mowing, tree service, food service, and entertainment companies to perform their trade.

This final rule will revise the Medicare hospital inpatient prospective payment systems (IPPS) for operating and capital-related costs of acute care hospitals; make changes relating to Medicare graduate medical education (GME) for teaching hospitals; update the payment policies and the annual payment rates for the Medicare prospective payment system (PPS) for inpatient hospital services provided by long-term care hospitals (LTCHs); update and make changes to requirements for certain quality programs; and make other policy- related changes. ONC also adopts certain health information technology (health IT) standards and specifications on behalf of HHS.
