NTU by Sincereways - became N600UA with Universal Airlines in 1998. Belly landing at Cold Bay (AK) in June 2011, as crew forgot to lower undercarriage

Built for United Airlines in Jan 1956. Seen here operating for Miami based Regal Air. Registered as 5Y-BMM in September 1997 for Sincereways of Kenya but remained stored at Opa Locka until sold to Universal Airlines as N37570 in August 1998. Re-registered N600UA in October 1998 and written off in June 2011 landing at Cold Bay Airport, Alaska (CDB/PACD), after a positioning flight from Togiak Village Airport, (TOG/PATG).

Ex N37570 , painted as 5Y-BMM from Sep 1996-Aug 1998 but was never taken up and N37570 was never de-registered by the FAA until re-registered N600UA 9th Oct 1998

Owned & operated by Universal Airlines. Over the years It had also been a familiar sight in Florida as N37570, HR-AKW and 5Y-BMM. Acquired by Universal Sep 98 as N37570 and re-reg N600UA a month later. To Race Coast Aviation in May 2010. Damaged beyond repair in a belly landing at Cold Bay AK 12 Jun 2011.

Still in the PAT Air cols I photographed it in at St Louis in Mar 80, now owned by Florida Aircraft Leasing. It went on to fly another 26 years with a variety of operators until ending up as N600UA with Universal Airlines. Damaged beyond repair in a belly landing at Cold Bay AK 12 Jun 2011 as N600UA with Universal Airlines. The crew got distracted and failed to lower the gear for landing!

Prior to this it operated for quite a number of different airlines. I have found no information about this particular airline, Sincereways. I don't believe that the aircraft was ever flown to Kenya but remained stored as such at Opa Locka since circa Oct 96 . By October 1998 it was registered N600UA with Universal Airlines and, whilst operating for them, was damaged beyond repair after a wheels up landing at Cold Bay Alaska 12 Jun 2011. The crew got distracted and forgot to lower landing gear!

Later damaged beyond repair in a belly landing at Cold Bay AK 12 Jun 2011 as N600UA with Universal Airlines. The crew got distracted and failed to lower the gear for landing!

This is the former United Air Lines N37570 "Mainliner Hawaii".
