747-400M

The 747-400M (a passenger/freight or "Combi" variant) first flew on June 30, 1989 and entered service with KLM on September 12, 1989. Based on the successful Combi versions of the Classic 747s, the −400M has a large cargo door fitted to the rear of the fuselage for freight loading to the aft main deck cargo hold. A locked partition separates the cargo area from the forward passenger cabin, and the −400M also features additional fire protection, a strengthened main deck floor, a roller-conveyor system, and passenger-to-cargo conversion equipment.^[26] The last 747-400M was delivered to KLM on April 10, 2002.^[18]
