Cargo Air orders two CFM56-7B blade sets for 2027-28 delivery

By Tom Whitfield

Cargo Air has ordered two sets of Chromalloy’s CFM56-7B High-Pressure Turbine (HPT) blade parts, with deliveries planned for 2027 and 2028.

Chromalloy announced the order for the Sofia, Bulgaria-based airline, which specializes in Boeing 737 cargo aircraft. The components fall under Chromalloy’s CFM56-5B/7B HPT Blade Parts Manufacturer Approval.

• Order: Two sets of CFM56-7B HPT blade parts.
• Delivery window: 2027 and 2028.
• Operator: Cargo Air, headquartered in Sofia, Bulgaria.
• Fleet relationship: Chromalloy solutions have supported Cargo Air’s B737-300/400 fleet for a decade.
• Regulatory status: The CFM56-5B/7B HPT Blade PMA received FAA approval in October 2025.

The order extends a working relationship that has already run for 10 years, turning established use of Chromalloy solutions into scheduled hardware procurement.

Chromalloy disclosed neither the order value nor the number of individual blades represented by each set. The announcement also does not divide the two sets between 2027 and 2028, identify the recipient airframes or set an installation timetable. Those gaps limit any near-term assessment of the order’s effect on aircraft availability.

What does this change for Cargo Air?

The immediate commercial effect is planned access to HPT blade parts for future B737 maintenance. It is not an aircraft purchase, and the announcement does not add a freighter, flight or cargo capacity.

HPT blades operate in the hottest section of the engine. That makes this a maintenance-supply transaction tied to continued operation of the airline’s Boeing 737 aircraft, rather than a general expansion of its cargo business.

Cargo Air Commercial Director and shareholder Angel Petrov said: “We are very pleased to partner with Chromalloy to support our B737 fleet while unlocking substantial engine maintenance savings in the future.”

Petrov identified lower engine-maintenance costs as the commercial objective. The announcement provides no savings amount, baseline, calculation method or date by which those savings will be realized.

For shippers, the crucial distinction is simple: a component order does not create additional lift. For forwarders, there is no new aircraft, schedule, route or rate information to incorporate into capacity planning.

Why approval and engine scope matter

Chromalloy said its CFM56-5B/7B HPT Blade PMA received FAA approval in October 2025. The regulatory milestone gives the purchase a defined approved-parts basis.

The CFM56-7B powers the Boeing 737 Next Generation family and is one of the most widely operated narrowbody engines in service. Those two facts place the order within an established Boeing engine ecosystem rather than a new or unproven propulsion program.

Cargo Air’s decade of Chromalloy use on its B737-300/400 fleet establishes the operator’s supplier history. However, the announcement does not specify which airframes within Cargo Air’s broader Boeing 737 operation will receive the ordered CFM56-7B parts.

Production stays inside Chromalloy

Chromalloy describes itself as the largest independent provider of turbine-engine hot-section and HPT blades. It produces the CFM56-5B/7B blade at its own facilities, where each part is cast, machined and coated.

The company says control over that full process supports consistent quality. The production detail gives buyers a concrete answer on where the three manufacturing stages occur: all at Chromalloy’s own facilities.

Russ Shelton, Executive Vice President, Business Development at Chromalloy, said: “Cargo Air has trusted Chromalloy solutions on its B737-300/400 fleet for a decade, and we are proud to continue our collaboration. This order shows the value Chromalloy PMA and repair solutions create for cargo operators.”

For Chromalloy, the commercial value lies in scheduled hardware business from an established customer. The order extends the relationship into the 2027-28 delivery window while reinforcing Chromalloy’s position as the original producer and service provider for the parts.

What shippers and forwarders should read into it

The announcement contains no capacity number, cargo tonnage, route schedule or freight rate. It cannot support an assumption that Cargo Air will add Boeing 737 freighter capacity or that air cargo pricing will change.

This is maintenance-component procurement, not fleet expansion. Any capacity effect would have to emerge later through aircraft availability and utilization, neither of which the announcement quantifies.

Forwarders should therefore leave near-term schedules and rate forecasts unchanged. The relevant milestones are delivery performance against the 2027 and 2028 schedule, installation of the parts and any future quantification of Cargo Air’s promised maintenance savings.

With the PMA FAA-approved since October 2025, the next tests are Chromalloy’s delivery performance and whether Cargo Air quantifies those savings; the order signals scheduled engine-parts supply, not a measurable rise in freighter capacity.
