UPS and FedEx have temporarily stopped flying their McDonnell Douglas MD-11 freighters while they conduct safety reviews in the wake of Tuesday’s deadly Louisville crash. The pause, which covers aircraft that account for a small but meaningful slice of each carrier’s widebody lift, comes as federal investigators probe why the jet’s left engine and pylon broke away moments after takeoff. The Federal Aviation Administration followed with an emergency directive requiring MD-11s to undergo inspections before returning to service.
UPS said it grounded its MD-11s “effective immediately” on Friday, noting the model represents about 9% of its airline’s fleet and emphasizing that contingency plans are in place to protect service. FedEx has also pulled its MD-11s from the line while it conducts a safety review and flexes its integrated air–ground network to keep time-sensitive freight moving. Both carriers acted after the manufacturer recommended operators suspend MD-11 flying pending additional engineering analysis.
The FAA’s emergency airworthiness directive, issued Saturday, prohibits MD-11 and MD-11F operations until inspections and any required fixes are completed—an order that applies to more than 100 U.S.-registered aircraft. The grounding formalizes steps the integrators had already taken and sets the conditions for a phased return once inspection protocols are met.
Investigators said cockpit voice recordings captured a repeating bell shortly after the crew advanced takeoff thrust; the warning persisted for roughly 25 seconds until impact. Video and on-scene evidence show the jet’s left engine detached as the aircraft attempted to climb, igniting a fuel-fed fire and leading to catastrophic loss of control. A preliminary report is expected in the coming weeks, but authorities have not yet assigned a cause.
The fleet impact is limited in percentage terms—roughly 9% of UPS’s aircraft and about 4% of FedEx’s—but concentrated in long-haul widebody capacity. That matters in November, when integrators typically lean on larger freighters to balance international linehauls and cross-country peak surges. Western Global Airlines is the only other U.S. operator of the type, with most of its MD-11s already parked, further tightening near-term substitution options.
What it means for trucking: In the short run, more parcels and high-value freight are likely to flow to the ground. Expect UPS and FedEx to re-time air volumes into daytime and weekend truck moves, lean harder on their linehaul networks, and use expedited team operations for lanes that typically piggyback on MD-11 long-hauls. That pivot can create spot demand for power-only and team-capable carriers near Louisville, Memphis, and key regional hubs, particularly on coast-to-coast and border-routing corridors.
Peak-season ripple effects should be manageable but noticeable. With inspections underway and two integrators reallocating lift to other aircraft types, trucking providers can anticipate: tighter overnight capacity on long miles; more short-notice tenders out of gateway markets; and incremental opportunities for temperature-controlled and hazmat-certified carriers as pharma and critical goods are prioritized. LTL networks may also see a bump in premium, day-definite upgrades as shippers trade air speed for ground reliability.
For shippers, the playbook is straightforward: build 24–48 hours of slack into time-definite routings that previously depended on MD-11 linehauls; flag urgent SKUs early for premium ground; diversify tender windows across late night and weekend slots; and stage inventory closer to customers to reduce reliance on long-haul air. Carriers should pre-clear surge capacity near integrator hubs, verify ELD-compliant team availability, and position trailers for drop-and-hook to capture overflow.
UPS and FedEx stress they are executing contingency plans to minimize service disruption as inspections proceed. The FAA’s directive sets the bar for returning the type to service; once inspection criteria are met, widebody lift should gradually re-enter the system, relieving some pressure on long-haul trucking lanes. Until then, ground carriers are poised to be the safety valve for urgent freight.
