b) Access to the top of the engine is achieved by undoing the camlock push and turn
fasteners attaching the top cowl to the other cowls. Wriggle them free, and lift off
the cowl. Reattachment is the reverse. Ensure all camlocks are securely locked!
c) Access to the lower engine requires the removal of the upper cowl, and then
removal of the lower engine cowl, secured by M4 fastenings. The cowl attachment
screws have a nylon washer between the screw head and the cowl, and must be
securely tightened.
d) Access to the battery, fuel filters etc is achieved by removing the firewall panel
between the engine and composite body, behind which they are located.
Mast
a) The rotor head fairing is removed by removing the M4 screws holding it to the body.
These to allow the rear fairing to the pulled off forwards. Reattachment is the
reverse, with screws securely tightened.
Standard system checks
Pitot and static ports.
The airspeed indicator pitot is a metal nozzle located at the nose of the aircraft.
The static ports are located either side of the fuselage under the doors, roughly 2/3rds of
the length along, and marked by white rings and black letters saying ‘Static port – do not
block!’ The static port connects to the ASI, Altimeter and VSI where fitted.
The integrity of this system is important, because a) a system leak could result in an under
reading ASI, leading to unintended flight speeds beyond Vne, and b) incorrect static port
balancing will lead to altimeter and ASI errors
A full system check is undertaken using a Barfield type apparatus (by following the
instructions with the test set) which will give a full system calibration. Alternatively a simple
system integrity test can be achieved using two 1ml syringes connected to the pitot and
static ports, with the second static port blocked. A full system calibration is normally
undertaken in the event of a problem found during the simple integrity test, or in the event
of a system rebuild or overhaul.
Pitot system integrity test
Check the ASI function and the integrity of the pitot-tube to ASI connection by use of field
test kit RSD7179. This consists of a modified Becton Dickinson D U-100 Insulin
hypodermic (or equivalent, and the needle is removed) and a short section of 6mm
silicone tube containing a one way valve.
