# The Export of Goods (Control) Order 1994, Paragraph 7B: Equipment, Assemblies and Components


Test, Inspection and Production Equipment
7B001 Test, calibration or alignment equipment specially designed for equipment specified in sub-category 7A except: equipment for Maintenance Level I or Maintenance Level II.
Notes:
1. Maintenance Level I
The failure of an inertial navigation unit is detected on the aircraft by indications from the control and display unit (CDU) or by the status message from the corresponding sub-system. By following the manufacturer’s manual, the cause of the failure may be localised at the level of the malfunctioning line replaceable unit (LRU). The operator then removes the LRU and replaces it with a spare.
2. Maintenance Level II
The defective LRU is sent to the maintenance workshop (the manufacturer’s or that of the operator responsible for level II maintenance). At the maintenance workshop, the malfunctioning LRU is tested by various appropriate means to verify and localise the defective shop replaceable assembly (SRA) module responsible for the failure. This SRA is removed and replaced by an operative spare. The defective SRA (or possibly the complete LRU) is then shipped to the manufacturer.
3. N.B.: Maintenance Level II does not include the removal of specified accelerometers or gyro sensors from the SRA.
7B002 Equipment, as follows, specially designed to characterize mirrors for ring laser gyros:
a. Scatterometers having a measurement accuracy of 10 ppm or less (better);
b. Profilometers having a measurement accuracy of 0.5 nm (5 angstrom) or less (better).
7B003 Equipment specially designed for the production of equipment specified in sub-category 7A, including:
a. Gyro tuning test stations;
b. Gyro dynamic balance stations;
c. Gyro run-in/motor test stations;
d. Gyro evacuation and fill stations;
e. Centrifuge Fixture for Gyro bearing;
f. Accelerometer axis align stations.
7B102 Reflectometers specially designed to characterise mirrors, for laser gyros, having a measurement accuracy of 50 ppm or less (better).
7B103 Specially designed production facilities for equipment specified in entry 7A117.
