How common is this?

Can anyone answer WHY only one winglet? very odd !

Yes, I can. If one wingtip sustains damage it can be removed and the aircraft operated to base for repair with a performance penalty. The removal of both wingtips gives a performance penalty which is considered too large so therefore cannot be done.

Going back to the five engined SAA 747 its not uncommon for the airlines to send replacment engines attached to another aircraft and quite a few of the modern airliners have a hard piont inboard of #2 engine for this purpose.

As to the winglets they are basically a device to reduce drag from the wingtip and thus increase range and efficency of the lifting surfaces in the wingtip area so the only detremental effect would be a few less miles on the range. certainly the extra lift on the other wing would, be compensated for by a little trim adn thefly by wire on then that have it .

Could have been damages and removed per MEL. I’m sure they take a performance penalty for having it removed.

Most definitely

There was a Eurocypria 737-800 in Manchester a few months ago I believe with just one winglet.

I believe the eurocypria aircraft with one winglet was only certified to fly to Amsterdam for repairs,they contacted Boeing and asked for guidance on operations for the said ship,and the reply was only allowed to fly for maitenance with one winglet….

Cash crunch? Till back in the 1980’s cars were sold with just one outside mirror, the other one being optional … 😀
