IAI opens North American 777-300ERSF freighter conversion lines in Marana

The first Boeing 777-300ER earmarked for Israel Aerospace Industries' 777-300ERSF freighter conversion has landed at Ascent Aviation Services' Pinal Air Park campus in Marana, Arizona, kicking off the programme's North American production base.

The aircraft comes from the portfolio of lessor World Star Aviation. Ascent's Marana facility will now serve as the North American conversion site for IAI's 777-300ERSF programme, and under a long-term agreement the MRO will run two parallel conversion lines dedicated to the type.

The launch rides on fresh infrastructure. Ascent has completed two purpose-built 90,000 sq ft widebody hangars at Marana, and the $70m investment triples hangar capacity at the site while expanding its heavy maintenance and widebody modification capabilities.

What does this change for cargo operators?

For carriers and lessors chasing converted 777-300ER freighters, it adds conversion capacity inside North America rather than relying on sites further afield. IAI says combining its certified conversion technology with Ascent's widebody MRO base expands global conversion capacity and gives customers more flexibility and support in the region. More slots, closer to home, at a moment when 777 P2F feedstock is moving through the market in volume.

IAI's programme holds a singular status: the 777-300ERSF is the world's first and only certified 777-300ER passenger-to-freighter conversion to date. It is also proving itself in service. In July the converted fleet surpassed 20,000 cumulative flight hours since the first aircraft entered commercial service in September last year.

The partners' words

Guy Bar Lev, IAI's president and chief executive, framed the move as strategy, not opportunism. He said: "Our vision is to shape the future of aviation by turning engineering innovation into lasting value for our customers. Passenger-to-freighter conversions are a key part of that vision, extending the productive life of aircraft and helping airlines adapt to changing market needs."

He added: "Establishing a conversion presence in North America advances our long-term strategy to strengthen IAI's position in the global commercial aviation market."

Yaacov Berkovitz, executive vice president and general manager of IAI Aviation Group, called the Marana start "an important milestone for IAI's global conversion programme" and credited World Star Aviation for bringing the first aircraft to Arizona and its confidence in IAI's technology.

David Querio, chief executive of Ascent Aviation Services, said the aircraft "marks the beginning of a long-term partnership with IAI and the first of many Boeing 777-300ERSF passenger-to-freighter conversions that will take place here in Marana". He pointed to growing demand for cargo conversions across the industry as the reason Ascent is investing now.

Why the lessor picked this platform

World Star Aviation did not hedge its choice. Partner Yoyo Allalouf said: "We chose IAI's 777-300ERSF P2F programme because we believe it is the strongest 777 P2F programme available at this most critical of times for 777 passenger to freight conversion production."

He added that Ascent's Marana facility provides the capacity and quality standards the lessor wants as it grows its freighter portfolio, calling the decision part of managing value for investors "across the cycle".

Fellow partner Garreth Slevin put the relationship in context: World Star's history with IAI in widebody P2F work stretches back to the 1990s and the 747-200 P2F programme. IAI's track record in widebody conversions, demonstrated by its 747 and 767 programmes, underpinned the decision to pick it again for the 777-300ERSF.

With two lines running at Marana and the type already accumulating flight hours in commercial service, IAI and its partners have widened the pipeline for 777-300ER feedstock at a point in the cycle when conversion capacity, not demand, looks like the binding constraint.
