The hot goss is that because SA are often after max loiter times, they're operating at such reduced power settings that the labyrinth (sp
) seals aren't sealing properly thus allowing some level of oil fumes into the aircon system.
Friends who operated the DH8 on RPT for several years (all marques to 300) have advised that in
normal operations, this was not an issue.
Rumour also has it that the internal publishing of fuel usage against skipper has exacerbated the problem.
