Duncan Aviation advises that all operators of Honeywell engines that do not run them frequently and want to keep them off the Damaged Engine List should spool them to N1 rotation speed once a month and make a logbook entry.

US Aviation in Denton, Texas, is the first FBO in the U.S. to install stainless steel-lined fuel tanks in its fuel farm. Traditional fuel storage tanks use an epoxy inner liner, and this liner “has a tendency to break down,” according to Jeff Soules, the FBO’s senior v-p and general manager. Benefits of the stainless-steel liners include no initial startup problems or chips, flaking or biological disintegration of the epoxy, he said.

Helicopters can perform a wide array of useful tasks that cannot be done at all or as well in a fixed-wing aircraft, so it probably stands to reason that an unmanned rotorcraft would soon prove its worth alongside fixed-wing unmanned air vehicles (UAVs). Schiebel’s Camcopter S-100 is fast finding acceptance for a variety of applications, such as pipeline surveillance for an undisclosed customer in Malaysia.
