Kits are manufactured by ICP Srl, Via Torino 12, 14020 Piovà Massaia,
Italy.
(3) CERTIFICATION BCAR SECTION S Issue 2. Except that:
Ignition switches on early aircraft may be fitted in the reverse sense so
long as the originally supplied, guarded, switches are fitted.

‘VG’ & ‘XLS’: 37.9 kg/m²
(d) Vso ‘Classic’: 28 kts CAS2
‘VG’ & ‘XLS’: 29 kts CAS
(e) Permitted range of occupant weights Min 55 kg total weight

1 Note: During aircraft construction, this HADS is to be used with the Savannah stage inspection sheets, form
BMAA/AW/022 (Savannah). If there is a conflict between the two, the latest HADS will always take
precedence. 2 VSO is based upon aerodynamic stall at aft CG, apparent stall speed may increase by up to 7kts CAS at further
forward CG positions. 3 The maximum ZFW is the lower of [(a)-(172kg+1hrs fuel)] or [(a)-(86kg+full fuel)].
4 Use of the higher maximum ZFW requires maximum continuous power to be limited to 2800 rpm by placard.

(d) ASI Placard
A correction placard from 30 to VNE at no more than 10 kts intervals, and at Vso, Va, VF and best glide
speed, must show the corrections from IAS to CAS. For values, see the approval MAAN for the
particular aircraft. An example is shown at Annex D.
In addition the ASI dial must be marked as follows (following calibration):
- Yellow triangle at 40 kts CAS, (recommended approach speed).
- White sector from 31 kts CAS to 56 kts CAS, (flap limits).
- Amber sector from 60 kts CAS to VNE
- Red radial line at VNE
Note: It is recommended that airspeed placards are not fitted to new aircraft until after flight testing, due
to the requirement for pitot-static system calibrations.
(e) Pitch Trimmer Instructions See Annex D.
(f) Switches See Annex D.
(g) Stick position
There is to be a line marked “Take-off trim” on the cabin floor at the correct stick position on the
ground with take-off trim set. This is to be 60 mm forward of the front edge of the lateral bracket
below the front of the seats. (Bungee trim system only)
(h) Maximum continuous RPM
If the increased maximum ZFW of 267kg for the Jabiru 2200 is used, a maximum continuous power of
2800 rpm must be placarded adjacent to the tachometer.

(e) Pitch Trimmer Instructions
PITCH TRIM nose down nose up
Also a line must be marked “Take-off” below the stick, 60mm forward of the seat front edge bulkhead
(bungee trimmer), or one line below middle (electric trimmer).
(f) Switches
All switches are to be marked with function and sense (up=on, down=off).
Note that the originally supplied, guarded ignition switches are ‘down=on’ on early aircraft; this is
acceptable due to the mode of operation but only applies to the original-specification ignition switches.
Where possible the switches should be orientated ‘up=on’.
Electric trim switches should be orientated ‘nose up’ = lower part of switch to be pressed.
(g) Flaps
The three flap lever positions are to be marked “0”, “18” and “36”, or “0”, “16” and “32” if the Mk 2
flap lever is fitted.
(h) Baggage compartment
To be placarded with it’s limit, which may not exceed 20kg. (See Annex C above for explanation)
ANNEX E
POINTS FOR SPECIAL ATTENTION
In service, the following points have been found to be commonly recurring problems, and Inspectors must give
special attention to the following both during initial approval, and during later inspections.
1. Special check at annual / 150hr inspection for any wear in control cables where they cross.
2. MPD 2006-006 must be complied with (BMAA SB 2013/1): modification of rear cross member.
3. Note that earlier examples may be placarded to a maximum seat weight of 86kg. This may be increased to
120kg provided a new weight and balance report is prepared and all relevant placards are altered
accordingly.
4. It has been noticed on a couple of examples that the weld on the aileron torque tube (connecting the control
stick to the bell crank mounted on the rear cross member) can come into contact with the nylon bush,
causing wear on the bush. This should be checked occasionally and if necessary a new torque tube and
bush should be sourced from SUp.
5. Piano hinges on the doors and anti-balance tabs should be crimped at the ends (to retain the hinge pins) at
the factory. If crimping is not present, contact the kit importer.
6. Check for any rubbing of skins against fairings.
7. Corrected elevator and anti-balance tab deflections to be observed.
8. MPD 2010-007 must be complied with (BMAA SB 2283/1): inspection and modification of pitch anti-
balance tab mechanism (bungee pitch trim).
9. MPD 2010-009 must be complied with (BMAA SB 1918/3): inspection for corrosion and abrasion of the
attachment plates of the front wing lift struts to the main wing spar (both sides).
