A disappointing mid-season period followed with a string of non-qualifications for the second FW as the "01" chassis had to be used again due to accidents. Van Lennep returned for the Dutch Grand Prix but failed to qualify and Merzario retired with a broken gearbox, having qualified down in 21st. For the French Grand Prix, Jean-Pierre Jabouille was brought in to replace the Dutchman but he also failed to qualify (the last appearance for chassis "01"), while Merzario started 15th and finished ninth. Belsø returned again for the British Grand Prix, although Jabouille also practiced, but the Dane failed to qualify. Merzario again started 15th but retired when his engine failed.
