Boeing 737s need 'bear strap' crack checks: What even is that?
Published Date: 8/6/2026
Rule
Summary
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-8, 737-9, and 737-8200 airplanes. This AD was prompted by reports of cracks in the bear strap at the forward upper corner of the forward galley door cutout. This AD requires an inspection of the fuselage skin for existing repairs and applicable on- condition actions. The FAA is issuing this AD to address the unsafe condition on these products.

Mandatory inspections for certain Boeing 737s
If you operate Boeing Model 737-8, 737-9, or 737-8200 airplanes identified in Boeing Alert Requirements Bulletin 737-53A1408 RB (dated December 20, 2024), you must inspect the fuselage skin for existing repairs and do the on-condition actions at the times specified in that bulletin. The AD is effective September 10, 2026, and applies to aircraft certificated in any category to address cracks in the bear strap and fuselage skin that may affect structural integrity.
Estimated inspection costs and unknown repair costs
The FAA estimates this AD affects 471 U.S.-registered airplanes. A general visual inspection is estimated at 1 work-hour ($85) per airplane (total $85 per airplane; $40,035 across U.S. operators). Detailed and eddy-current inspections are estimated up to 4 work‑hours ($340) per airplane per inspection cycle (up to $340 per airplane; up to $160,140 across U.S. operators per inspection cycle). The FAA did not have definitive cost data for on-condition repairs or alternative inspections.

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.
2026-16129, Special Conditions: ATR-GIE Avions de Transport Régional Model ATR42-500 and ATR72-212A Airplanes; Electronic System Security Protection From Unauthorized Internal Access
The FAA is setting new safety rules for ATR42-500 and ATR72-212A airplanes because they have a cool new digital system that lets people inside the plane access its electronics through wireless and wired networks. These rules make sure this tech is just as safe as older systems. The changes kick in on August 7, 2026, and anyone can share their thoughts by September 21, 2026—no extra costs expected.
2026-16157, Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by a report indicating that the protection system on the left fan cowl of the right engine does not sufficiently cover the components and systems from possible cross engine debris. This proposed AD would require performing a maintenance records check or inspection of the right engine to determine the part number of the left fan cowl and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.

The Food and Drug Administration (FDA or we) received objections and requests for a public hearing submitted by Buchanan Ingersoll & Rooney PC, on behalf of Micro-Tracers, Inc. (Micro-Tracers or objector), on the order granting a color additive petition (3C0323) requesting that we repeal specified regulations to no longer provide for the safe use of FD&C Red No. 3 in food (including dietary supplements) and ingested drugs. After reviewing the objections, we have concluded that the objections do not raise issues of material fact that justify a hearing. We are also providing notice that the administrative stay of the effective date for the repeal and delisting of the color additive regulations is now lifted.

The Food and Drug Administration (FDA) is classifying the fludeoxyglucose F18-guided radiation therapy system into class II (special controls). The special controls that apply to the device type are identified in this order and will be part of the codified language for classification of the fludeoxyglucose F18-guided radiation therapy system. We are taking this action because we have determined that classifying the device into class II will provide a reasonable assurance of safety and effectiveness of the device. We believe this action will also enhance patients' access to beneficial innovative devices, in part by reducing regulatory burdens.
