On October 21 2016, it was reported that a Canadian helicopter company Heli-One will upgrade all Malaysia's Nuri helicopter. On November 9 2004, a Mikoyan MiG-29 crashed into an oil palm plantation in Kemaman, Terengganu. The pilot survived the crash. In May 2008, two J85-GE-21 engines that power the Northrop F-5E Tiger II fighter jets belonging to the Royal Malaysian Air Force were reported missing, as of sometime in 2007, from an RMAF warehouse in Kuala Lumpur during Najib's tenure as Defence Minister in Abdullah Ahmad Badawi's cabinet. The jet engines belonged to the 12th Squadron (Scorpion) based in Butterworth.
