Honeywell International, one of the world’s largest manufacturers of auxiliary power units for aircraft, did not stifle competition in the unit-repair market, the Ninth Circuit ruled Friday.
US Circuit Judge M. Margaret McKeown outlined the underlying dispute in her 32-page opinion.
Honeywell is one of two major manufacturers of units that provide aircraft with electric power. Aerotec International, which is not affiliated with Honeywell, is a repair company that works on Honeywell’s units. In 2006, Aerotec began a major push to increase its less-than-one percent market share, winning contracts from companies like Saudi Arabian Airlines and Air India.
Honeywell offers repair services for its units as well and enjoys a significant leg up on the competition because it builds its own replacement parts. Aerotec, as an independent company, purchases replacement parts from Honeywell but pays more for them than do the airlines and Honeywell affiliates.
