The number of Frattini chief factors or of chief factors which are complemented by a maximal subalgebra of a finite-dimensional Lie algebra $L$ is the same in every chief series for L, by Theorem 2.3 of D. A. Towers [Maximal subalgebras and chief factors of Lie algebras, J. Pure Appl. Algebra 220 (2016) 482--493]. However, this is not the case for the number of chief factors which are simply complemented in L. In this paper we determine the possible variation in that number. The same question for groups has been considered by Seral and Lafuente [On complemented nonabelian chief factors of a finite group, Israel J. Math. 106 (1998) 177--188].
