Airborne and Partners Develop ADS-B In Retrofit for Boeing 757 and 767

This article is based on an official press release from Airborne Maintenance & Engineering Services.

Airborne Maintenance & Engineering Services, a subsidiary of Air Transport Services Group (ATSG), announced a strategic Partnerships on April 20, 2026, with Innovative Aerosystems (IA) and Aviation Communication & Surveillance Systems (ACSS). The coalition aims to develop and certify an ADS-B In retrofit solution specifically designed for Boeing 757 and 767 aircraft, with an expected entry into service in early 2027.

According to the official press release, this initiative arrives at a critical juncture for aviation safety and regulatory compliance. Just days prior to the announcement, on April 14, 2026, the U.S. House of Representatives overwhelmingly passed the Airspace Location and Enhanced Risk Transparency (ALERT) Act. This sweeping aviation safety bill mandates the implementation of ADS-B In technology across the industry by December 31, 2031.

We note that this retrofit program represents a proactive industry response to impending federal mandates. It offers operators of legacy Boeing 757 and 767 fleets a cost-effective pathway to modernize their flight decks, ensuring compliance with future airspace requirements while enhancing operational efficiency.

The Regulatory Catalyst and the ALERT Act

Tragic Origins and Legislative Action

The legislative push for ADS-B In technology gained intense momentum following a tragic midair collision on January 29, 2025. The incident, involving a PSA Airlines CRJ700 and a U.S. Army UH-60 Black Hawk Helicopters near Ronald Reagan Washington National Airports (KDCA), resulted in 67 fatalities. Subsequent investigations by the NTSB revealed that the helicopter was not broadcasting an ADS-B signal, exposing a critical gap in cockpit situational awareness.

In direct response to the NTSB’s 50 safety recommendations, lawmakers introduced the ALERT Act. The legislation requires all aircraft currently mandated to have ADS-B Out to be equipped with ADS-B In and corresponding collision prevention technology by the end of 2031. A competing Senate bill, the ROTOR Act, pushes for a similar mandate.

“Any safety requirement that routes implementation through negotiated processes… creates opportunities for delay that cost lives. This is how modern aviation operates. ADS-B In is proven technology that can be deployed now to save lives,” stated U.S. Rep. Rob Bresnahan, Jr., co-sponsor of the ADS-B In amendment to the ALERT Act.

Technological Integration and Key Partnerships

Upgrading the Legacy Fleet

While ADS-B Out, mandated in the U.S. since 2020, broadcasts an aircraft’s position, speed, and altitude, ADS-B In allows the flight deck to receive this data from other aircraft and ground stations. This provides pilots with a real-time, 180-nautical-mile display of surrounding traffic. The retrofit program leverages the ACSS SafeRoute™ system, which includes features like Airborne Traffic Situational Awareness (AIRB), CDTI Assisted Visual Separation (CAVS/CAS), Interval Management (IM), In-Trail Procedures (ITP), and runway surface alerting (SURF-A).

Each partner brings specific expertise to the integration. Airborne will lead the aircraft integration, Supplemental Type Certificate (STC) certification, and installation. Innovative Aerosystems (IA), which rebranded from Innovative Solutions & Support in October 2025, will provide the retrofit Flat Panel Display System. ACSS, a joint venture between Acron Aviation and Thales, supplies the core SafeRoute™ software and TCAS 3000SP platform.

“This program focuses on integrating ADS-B In capabilities into existing flight deck environments with minimal disruption,” noted Mike Glover, VP of Business Development at Innovative Aerosystems, in the press release.

Operational Efficiency and Fleet Modernization

Minimizing Downtime for Cargo Operators

ATSG is the world’s largest lessor of converted Boeing 767 freighter aircraft, operating a fleet of over 114 converted Cargo-Aircraft jets. These aircraft serve as the backbone for major e-commerce logistics providers. By synchronizing the ADS-B In installation with scheduled heavy maintenance, ATSG aims to minimize aircraft downtime, a crucial factor for cargo operators relying on tight schedules.

“They need integrated capabilities that can be executed efficiently and at scale… Airborne’s technical expertise, combined with ATSG’s broader platform, allows us to deliver programs like this in a way that reduces complexity, minimizes downtime, and creates immediate and long-term value,” said Todd France, Chief Commercial Strategy Officer at ATSG.

AirPro News analysis

At AirPro News, we view this partnership as a highly strategic alignment of capabilities that addresses a “perfect storm” of safety mandates and operational efficiency. The Boeing 757 and 767 remain vital to the global e-commerce cargo network. This retrofit allows these legacy workhorses to operate in modernized, NextGen airspace without requiring operators to invest in entirely new airframes. Furthermore, while safety mandates typically introduce new costs, the fuel efficiency and optimized routing enabled by ADS-B In’s Interval Management and In-Trail Procedures offer a tangible return on investment for cargo airlines.

Frequently Asked Questions

What is the difference between ADS-B Out and ADS-B In?

ADS-B Out broadcasts an aircraft’s GPS location, speed, and altitude to air traffic control and other aircraft. ADS-B In allows an aircraft to receive this broadcasted data, providing pilots with a real-time display of surrounding air traffic and enhancing situational awareness.

When does the ADS-B In mandate take effect?

Under the ALERT Act passed by the U.S. House of Representatives on April 14, 2026, aircraft currently required to have ADS-B Out must be equipped with ADS-B In technology by December 31, 2031.

Which aircraft are covered in this specific retrofit program?

The partnership between Airborne, Innovative Aerosystems, and ACSS is specifically developing and certifying an ADS-B In retrofit solution for Boeing 757 and 767 aircraft.
