I operated in the area concerned for a short period of time and agree with the comments WLM made. On top of that i applied the law of common sense and paranoia by carrying basic tools and watched the maintenance people with a caring but subtle over the shoulder eye if you know what i mean. Most of all the driver should have a very good understanding of the machinery they fly, unfortunately the local guys dont. Hornbill has had a bad run and the problem i feel is ingrained with the Malaysian system and may be hard to rectify.
Gday WLM and hang in there!
