Is It Possible To Convert 777-300ER To Combi?

Wed Feb 08, 2006 6:45 am

Hello all

I was wondering is it possible to convert 777-300ER to combi version?. I understand the weight issue will be heavier, I know the range will be shorter and it will burn more fuel. Just for the sake of it can it do it? It will carry additional cargo just like the ex AC 747-400 combi.

comments are appreciate please.

It can be done. Only problem is whether the FAA is willing to certify it. I recall the FAA has beefed up the regulations regarding the certification of combis. Except for those that have already been fully certified, new Combis would require a fixed wall that separates cargo from passengers, which would take away some flexibility from combi operators.

Anyone have pics of a 747 combi from the inside, both passenger and cargo views? How short was the passenger cabin?

The FAA will only certify an aircraft that a fixed and solid barrier between human and freight cargo on the same deck. This is to ensure adaquet fire and materials safety.

Problems being (1) finding a customer who wants a combi that bad to jump through the necessary hoops, (2) the solid partition mitigates some of the flexibility and alure of combi aircraft.

Retrofitting a rigid cargo barrier probably isn't the biggest challenge. Modifying the carbon fiber floor beams would be an issue. Most likely, they would need to be completely replaced in the combi zone, because Boeing won't support any modifications to them. Eventually it get to a point where you might as well buy a new plane.

Actually that is quite correct, Air Canada's B747-400 Combis were permenent combis as they had fixxed barriers and beefed up floors. AC could not change from full pax to combi, it was a fixed combi. This caused the plane to burn more fuel then other combi B744's and pax B744's.
