Design and development
Following the test flying of the Doman LZ-2A, Doman Helicopters developed an eight-seat helicopter with the designation LZ-4.[1] The fuselage had 3 rows of double seats in the main cabin and a two-crew flight deck in the front. Large folding doors allowed for loading bulky cargo into the main compartment. The tail boom was conventional with a cranked-up rear section mounting a tail rotor, and the helicopter was supported by a four-leg undercarriage.[3]
