If G is a projective special linear group PSL(3,q) with q ≡ 4 or 7 (mod 9), then a Sylow 3‐subgroup of G is elementary abelian of order 9. We show that the principal 3‐blocks of any two such groups are Morita equivalent. This result and Okuyama's theorem for PSL(3,4) prove the Broué conjecture for these blocks. 1991 Mathematics Subject Classification: 20C05, 20C20.
