02/28/2008. Remarks by Johan Visschedijk: "Derived from the twin-engined LeO H-24 (first flown November 1929 as F-AKBX, reregistered F-AKDX in April 1932), the LeO H-242 was a four-engined flying boat that could carry ten passengers. The first of two constructed flew for the first time on March 30, 1933. Registered as F-AMOU and F-AMUL (c/n 1 and 2), they were delivered to Air France in December 1933 and February 1934.
Pictured is one of the twelve series production LeO H-242.1. Powered by the same 350 hp Gnome-Rhone 7 Kd single-row seven-cylinder radial engines that powered the LeO H-242, it could carry 12 passengers, and had a slightly improved performance. The twelve aircraft (c/n 3 to 14) were delivered to Air France between March 1935 and May 1937, registered respectively as F-ANPM, F-ANPA to F-ANPE, and F-ANQF to F-ANQK."
