Far away places with strange sounding names have always been attraction for me.
I can verify and update on one leg of the RTW flight, specifically the sojourn in Subang Airport Kuala Lumpur (not Kulang) where the 182 was serviced by a Mr. Mutalib. Mr. Mutalib now services my own 182 based at Bernam River Airfield (WMBR) North of Kuala Lumpur. A very willing and cooperative gentleman nothing is too much for him.
A great site Jeab, fly safe and keep the blue side up.
