The requirements of this Chapter are applicable
to gas turbines for main propulsion and also, where powers exceed
110 kW (150 shp), to those for essential auxiliary services. The requirements
do not apply to exhaust gas turbo-blowers.
Approval will be in respect of the mechanical integrity of the
gas turbine (including gas generator and power turbine), intake and
exhaust ducting configuration, acoustic enclosure configuration (where
appropriate), fuel, lubricating oil and starter systems, control alarm
and monitoring systems and other critical support systems.
Type
approval of the gas turbine bare engine will be required as part of
the approval process for first of type.
Primary exhaust
gas emissions abatement plant (where fitted) is to meet the requirements
of this Chapter; additionally, it shall meet those of Pt 5, Ch 24 Emissions Abatement Plant for Combustion Machinery. Where secondary exhaust gas
emissions abatement systems are fitted to gas turbines, they are to
meet the requirements of Pt 5, Ch 24 Emissions Abatement Plant for Combustion Machinery.
