CRJ Modification Possible?

Fri Mar 23, 2007 2:24 am

Bloomberg:

Quote:
US Airways also will lessen its stock of small regional jets, making room for mid-size jets, such as its 86-seat Embraer E190. "What we're trying to do on the (US Airways) Express fleet is up-gauge our aircraft," Kerr told reporters. "Every chance we get to bring in larger aircraft and we reduce the 50-seat aircraft, we do that. ... You will continue to see us getting out of 50-seat aircraft (in favor of) 86-seat and 90-seat aircraft," CFO Derick Kerr said.

With so many 50 seat CRJs out there, which were once not too long ago seen as industry saviours, are now unfortunately relegated to the status of pariahs; would it be possible/profitable to insert fuselage plugs into existing airframes to increase their capacity?

For some airlines it might be a more affordable option than purchasing new CRJ700s.

It just seems such a waste to send to the rubbish bin perfectly good airplanes, but I am not an engineer nor a airline cost analyst, just a curious observer....

Many aircraft have been modified over the years, and had long happy lives in their new roles, why could it not happen with the CRJ?

Quoting Stirling (Thread starter):

With a CRJ-700 you get slats, bigger cabin and whole new wing, more powerful engines, 2 belly cargo bins plus the normal aft bin..etc. It wouldn't work and would cost a lot more than buying a new or used plane of the larger size.
Good Luck to all Skyway Pilots! It's been great working with you!

Skyex hit it on the nail. The CRJ -700 and -900 series aircraft are incredibly different than the -200 series. Much moreso than just being longer.
I'd take the awe of understanding over the awe of ignorance any day.

I've heard of a cargo conversion, so that's a possibility. Or it may be that corporate conversions may find a market.

Would not work Stirling. First the wings would not have enough lift and fuel capacity. Next you need bigger engines, bigger capacity air systems, bigger gear, etc. Airlines will live with them until they get beyond their economic life.
