Jan 17 (Reuters) - Boeing is moving into making aircraft seats in a bid to reduce costly delays to deliveries by plane manufacturers, forming a joint venture with car seating leader Adient.
Adient Aerospace will develop and sell seats to airlines and leasing companies, both for installation on new airplanes and as retrofits on planes made by Boeing and rival manufacturers, the two companies said late on Tuesday.
They cited forecasts suggesting the aircraft seating market would grow from $4.5 billion in 2017 to $6 billion by 2026.
Adient's tie-up with Boeing is the industry's latest response to industrial problems in aircraft interiors, with congestion in cabin supplies contributing to late airplane deliveries in the past two years.
These can cost airplane manufacturers $100,000 a day, said Vertical Research Partners analyst Rob Stallard, making the bottlenecks in aircraft seating a top industry priority.
Adient, spun off from Johnson Controls in 2016, is the largest automotive seats maker, with a 34 percent share of a business dominated by five companies, and its 75,000 workers supply seats and interiors for 25 million vehicles a year.
Traditionally, aircraft seat makers like B/E Aerospace and Zodiac Aerospace sell seats directly to airlines, a process that can involve multiple customised designs and regulatory approvals and lead in turn to industrial delays.
France's Zodiac is in the process of being taken over by French engine maker Safran after a three-year factory crisis and a spate of profit warnings.
The new venture deepens Boeing's involvement in the supply chain for cabin interiors after it introduced a new supplier of economy-class seats for its top-selling 737 series in late 2016: Huntington Beach, California-based LIFT by EnCore.
That was seen as the first deal in which Boeing had agreed to buy seats from the supplier and offer them directly to airlines in an effort to reduce risk.
European planemaker Airbus made a similar move in 2015, choosing German seat maker Recaro to supply A320 seats.
"Seats have been a persistent challenge for our customers, the industry and Boeing, and we are taking action to help address constraints in the market," Kevin Schemm, supply chain and finance chief for Boeing Commercial Airplanes, said.
The new venture reflects a shift by manufacturers like Boeing and Airbus towards greater vertical integration to reduce industrial risks and capture margins from suppliers.
Adient Aerospace's headquarters and initial factory will be based near Frankfurt and it will be 50.01 percent-owned by Adient. No financial details were released.
