Final AD. It covers certain Boeing 737-600 through -900ER airplanes identified in Boeing bulletin 737-55A1104 RB, after several operators reported pitch oscillations caused by excessive horizontal stabilizer freeplay. It requires measuring freeplay at the pivot hinges and jackscrew, with follow-up actions. Effective 35 days after publication (November 23, 2026, if it publishes Monday as scheduled).

Why this matters to you: Delta flies 737-800 and -900ER aircraft, so applicability by line number in the Boeing bulletin should be checked against the fleet now (Our assessment, not stated in the document.)

Final AD. It covers Boeing 737-600 through -900ER airplanes with video monitors mounted on the passenger service units, after monitors came loose during a hard landing. It requires replacing monitors that lack secondary retention lanyards, at the times set in Boeing bulletin 737-25-1851 RB Rev. 1. Effective 35 days after publication (November 23, 2026, if it publishes Monday as scheduled).

Why this matters to you: If any Delta 737-800 or -900ER aircraft still carry PSU-mounted video monitors without lanyards, this is a cabin-interior work package (Our assessment, not stated in the document.)

Final AD. It covers all Airbus A330-841 and -941 (A330neo) airplanes and supersedes AD 2025-04-05 on leaking engine bleed air high-pressure valves. It keeps the flight manual, MEL and valve-test requirements, ends repetitive clip replacement because an improved valve has been certified, and requires a bleed monitoring computer software update. Effective 35 days after publication (November 23, 2026, if it publishes Monday as scheduled).

Why this matters to you: This applies to every A330-941, which is the A330-900neo Delta operates, so it means a software update plus continued valve tests and MEL procedures (Our assessment, not stated in the document.)

Final AD. It covers all Airbus A330-243, -243F, -341, -342, -343, -841 and -941 and the A340 models listed, after reports of leaking fuel low-pressure shut-off valves. It requires repetitive leak checks and replacement of discrepant valves under EASA AD 2026-0060R1. Some initial checks are due within 35 months. Effective 35 days after publication (November 23, 2026, if it publishes Monday as scheduled).

Why this matters to you: The A330-941 is named in the AD, and some older Delta A330 variants may be too, so recurring fuel valve leak checks should be scheduled (Our assessment, not stated in the document.)

Proposed AD. This would replace AD 2025-09-07 for Airbus A330-941 airplanes identified in EASA AD 2025-0286. It keeps the flight manual and MEL changes for dual loss of radio management panel synchronization, adds a required modification and limits installation of affected parts. Comments are due 45 days after publication (December 3, 2026, if it publishes Monday as scheduled).

Why this matters to you: Delta's A330-900neo fleet may be among the airplanes in the EASA AD, so this is a chance to comment on the modification before it becomes final (Our assessment, not stated in the document.)

Final AD. This replaces a 2009 AD for Rolls-Royce Deutschland BR700-715A1-30, -715B1-30 and -715C1-30 engines. Operators must revise the airworthiness limitations in their engine maintenance programs to adopt the manufacturer's new or more restrictive life-limited-part tasks, thresholds and intervals. Effective 35 days after publication (November 23, 2026, if it publishes Monday as scheduled).

Why this matters to you: The BR700-715 is the engine on the Boeing 717, a type Delta still flies, so this probably does apply despite the Rolls-Royce Deutschland name. The AD itself names only engines, not airframes (Our assessment, not stated in the document.)

Final AD. All Pratt & Whitney PW4052 through PW4462 series engines listed in the AD must have their pressure burner (Pb) sensor replaced with one under 30,000 flight hours and under 10 years since new or last repair, following reports of tailpipe fires, loss of thrust control and in-flight shutdowns. Effective 35 days after publication (November 23, 2026, if it publishes Monday as scheduled).

Why this matters to you: PW4000-94 engines of this family power some Boeing 767 aircraft, so Delta should check whether any of its 767 engines are covered (Our assessment, not stated in the document.)

FCC Wireless Bureau notice seeking comment. Under the FCC's July 2026 Upper C-band order, new 3.7 GHz licensees will pay rebates to eligible aircraft owners and operators to help cover FAA-mandated radio altimeter retrofits. This notice proposes the rebate categories, dollar amounts and procedures. Comments are due October 26, 2026, and replies November 16, 2026 (GN Docket No. 25-59).

Why this matters to you: Delta will likely need FAA-mandated radio altimeter retrofits across many aircraft, and this notice sets how much the rebates pay, with comments due October 26 (Our assessment, not stated in the document.)

FCC Wireless Bureau notice seeking comment on the preliminary Upper C-band Transition Cost Catalog. The catalog estimates the reasonable transition costs that satellite operators and incumbent earth station operators may incur as they move out of 4.0 to 4.16 GHz, freeing 160 MHz for 3.7 GHz Service licensees across the contiguous United States. It also sets lump-sum payment categories for earth stations. Comments are due October 20, 2026, and replies November 9, 2026 (GN Docket No. 25-59).

Why this matters to you: This is not about airlines directly. The pace and cost of moving satellite users out of the band drive when 5G service starts in the Upper C-band, and that sets the timeline for the radio altimeter retrofits in Your Operations (Our assessment, not stated in the document.)

Final AD for Boeing 787-8, -9 and -10 airplanes with Rolls-Royce Trent 1000 engines, requiring a check of the left fan cowl on the right engine for cross-engine debris protection. Effective about November 23, 2026.

Why this matters to you: Delta does not currently fly the 787, but this is useful background if it evaluates the type (Our assessment, not stated in the document.)

Proposed AD that would replace AD 2026-09-02 on PW4074 through PW4090-3 engines, adding an omitted part number and keeping repetitive ultrasonic inspections of compressor and turbine parts. Comments are due about December 3, 2026.

Why this matters to you: These are Boeing 777 engines, a type Delta no longer flies, so this matters only for leased or acquired 777s (Our assessment, not stated in the document.)

Proposed AD for Airbus Helicopters. Only the title was reviewed. We will summarize it in full once it publishes.

Why this matters to you: Delta does not operate helicopters (Our assessment, not stated in the document.)
