Correction: An earlier version of this obituary contained several errors. Mr. Kappaz died Jan. 27 on an airplane bound for Panama, not Jan. 28 at a hospital in Panama. The first and last names of a surviving daughter, Christina Kappaz Ardila, were misspelled. He has 21 surviving grandchildren, not 12. His company, K&M Engineering and Consulting, was started in 1986, not in 1987. The obituary has been corrected.

Michael Kappaz, 70, the chairman and chief executive of engineering and consulting companies specializing in international power and telecommunications projects, died Jan. 27 while on a flight from Washington to Panama.

He co-founded the Washington-based K&M Engineering and Consulting group of companies, which completed projects in Africa, Latin America and the Middle East.

He graduated in 1970 from the Polytechnic Institute of New York University and received a master’s degree in business administration a year later from Golden Gate University in San Francisco.

Mr. Kappaz was a past trustee of the Washington National Opera and helped recruit Spanish-born tenor Placido Domingo as the opera’s general director.
