Delivered new to the RMAF in January of 1977 carrying serial FM-1720. It was then re-serialled to M23-16 in 1984 and is reported to have briefly carried civilian registration 9M-ZAR in 2008 (for modification and certification work?). A total of 16 RMAF S-61's were written off over the years, with M23-16 being the last one, suffering a hard landing on August 2, 2019. Actually, this very accident - luckily without loss of life - sealed the fate of the surviving 12 or so RMAF's Nuris, as the fleet was permanently grounded. Keeping them airworthy has become an issue in the previous years anyway.
