Dassault Aviation has reached a settle-ment with Honeywell over a $60 million lawsuit filed by the French business jet builder in October last year.

The complaint stemmed from software integration holdups with Honeywell’s Primus Epic avionics platform, the baseline system behind the EASy cockpits in the Falcon 900EX and 2000EX. In the lawsuit, Dassault claimed that Honeywell assured it that the basic functionality of Primus Epic was ready in mid-1999 when in reality the avionics system still required considerable development, leading to a nearly three-year delay in certification of the 900EX.

Terms of the settlement were not disclosed. In a statement, Honeywell said it had reached a “mutually satisfactory resolution” with Dassault about the matter and that it looks forward to continuing the companies’ “longstanding and successful relationship.”

In its lawsuit, Dassault had claimed that Primus Epic setbacks and the ensuing certification delays damaged the manufacturer’s reputation for delivering airplanes on time. Dassault even contended that at one point Honeywell requested dozens of engineers be “loaned” to Honeywell to assist with EASy software coding. Dassault also claimed that production shipsets of Primus Epic hardware arrived late, were in poor condition and did not meet agreed-to specifications.

The Primus Epic avionics system is flying today aboard a variety of business jets, helicopters and regional airliners, including the Gulfstream G550 and G450; Agusta AB139 helicopter; Embraer 170/175 and 190/195 regional jets; the Dassault Falcon 900EX, 2000EX and 7X; Cessna Citation Sovereign; and Raytheon Hawker 4000.
