Question About LH's Converted 74Ms.

Sat Mar 24, 2012 4:19 pm

LH have a few 74Ms converted to full PAX configuration. However, do these aircraft (D-ABTA, B, C) still operate as 747-400Ms or do the operate under the 747-400 designation (converted to 747-400s)? Is it similar to SAS that converted their MD81s to -82s?

None of the aircrafts operate as freighter, not full, not half. The cargo door is closed and sealed and cannot be opened easily again.
In the flight deck we still have the indication for that doof, but of course it is always closed.

It depends if Lufthansa sold the combi kits of these aircraft. If these kits have been sold it's very difficult (expensive) to convert the aircraft from an all passenger configuration in a 7 pallet Combi-configuration again. This 7 pallet configuration is the only certified combi configuration at this moment, with the halon knockdown system installed. The earlier available 13 pallet configuration has not been re-certified after the Heidelberg (SAA- 747 combi) disaster.

If the kits are sold they are in fact dedicated full passenger aircraft, but are still listed as 747-430BC aircraft, with a main deck cargo door and heavier aft floor-beams and a heavier cargo-floor installed and some other small differences.

Note : KLM operates at the moment one 744 combi in all passenger configuration, but still has the kit available for a possible configuration change to the combi configuration. All others 744 combi aircraft are operating in the 7 pallet mode, with the main deck halon fire suppression system installed.
Operating a twin over the ocean, you're always one engine failure from a total emergency.

Yes I know that, but are they still seen as 747-400Ms or do they operate under the 747-400 designation?

SAS had a few MD81s, converted them to -82s, and now those ex -81s operate as MD82s. Now, is it the same with LH?

Just a small correction, the aircraft was actually named the Helderberg, not the Heidelberg.

Boeing's O&D site lists them as -430Ms, while Airfleets.net shows them as all -430s.
