Just on a point of order, not even the Marshall converted L1011 freighter can/does exceed its original pax designed floor load limit.
This "Natali" was actually "reconfigured", not converted, - like so many other operators do/used to do. Pax by day and bulk-loader by night.
"Natali" has aircraft grade riffled alluminium floor coverings fixed to the original floor over the original floor covering, obviously with carpets removed. No new holes or bolts.
Egli used sheets of wooden ply-wood to cover the floor.
These "reconfigured" L1011's however fell flat with the/a cargo bulkhead requirement. The home-made installations does not meet manufacturers design specifications/requirement, and the manufacturer and few authorised STC holders are/were not even prepared to talk to these operators. In short these were backyard conversions for which there is no STC and no official approvals.
Egli did well with his bulkloaders initially out of Ostend and when they complained, out of the UAE to Africa and Bangladesh. When the UAE started turning on the pressure he relocated to Chad where his machines eventualy expired.
"Natali" is a model 200 with -524 engines and had lots of potential, last operated by Tradewinds and then placed in "hibernation" just a few hours after a C-Check. Soon after she was bought by the new owner and after it started flying it quickly became clear why Tradewinds had parked her. The No 3 engine was bad and immediately started giving problems up to when "Natali" made an emergency landing in Sabina Ghoken (Ankara).
It stood in Ankara for about 18 months before positioning to Bangladesh where the owner was promised registration and an CofA. Since then its seems the Bangladesh CAA have gotten cold feet and it has never flown successfully again and is now stuck in Dhaka, probably for good.
In Africa 55 tons loaded on skids took about 8 hours to load and even longer to off-load. In Europe about double that time.
