SPECIFIC EXPERIENCE TASKS FOR SAILPLANES, POWERED SAILPLANES and BGA TUG INSPECTOR AUTHORISATIONS These are the general experience requirements for the issue of a BGA Inspector authorisation. Not all inspectors will achieve all the tasks below but a good percentage will be required to achieve a minimum standard. These requirements also align with the proposed Part 66 L licence. The experience record should be recorded on BGA PER sheets stating the date, aircraft type and registration, details of the experience and confirmed by someone in a responsible position AIRFRAME GENERAL (AF) (formally GL) General Activities Internal and external placards; check or replace Annual Inspection Documentation Review records for compliance with airworthiness directives Five Annual Inspections Inspection after an occurrence or damage Dismantling/reinstallation of wings and empennages Cleaning and lubrication Life extension inspections Levelling and weighing Level the sailplane Weighing, Weight & Balance Sheet Prepare a weight and balance amendment Check the list of equipment Fuselage, wings and tail surfaces Fuselage and fin; Inspection, cleaning and waxing Wings; Inspection, play, frequency check, cleaning and waxing Tail surfaces; Inspection, cleaning and waxing Flight Controls and Flight Control Systems Pilot controls general; Inspection, colour coding and operation Aileron and Flaps; Inspection, removal, balancing and reinstallation Elevator; Inspection, removal, balancing and reinstallation Rudder; Inspection, removal, balancing and reinstallation Control cables; Inspection, fabrication, installation, tensioning and locking Control pushrods; Inspection, removal, installation, adjustment and locking Trimmer systems; Inspection, removal, installation, adjustment and locking Safeguarding of pins, screws, castellated nuts and wire locking Sealing of gaps Range of movement checks Independent inspections BGA Inspector Experience Guide 02/2013 Page 1 Electrical Systems Electrical components and wiring; Inspection, removal, repair and installation Batteries; servicing and capacity checking Avionics Systems COM; Inspection, removal, installation and testing NAV; Inspection, removal and installation XPDR; inspection, removal and installation Antenna/ Antenna cable; Inspection, removal and installation Cabin Equipment / Systems Belts – safety harness; inspection, removal and installation Oxygen system; Removal, installation, testing requirements and safety precautions Canopy; Inspection, polish, replacement or repair and jettison test Pitot/Static system; Inspection, component and plumbing removal, installation and test Flight instruments; Inspection, removal, installation and test Installation of approved equipment Compass; Installation and compensation Tow release; Inspection, removal, installation and test Water ballast system; inspection, removal, installation and test Undercarriage; Inspection, removal, installation and function test Skids; Inspection, wear assessment and replacement Brake system; Servicing, inspection, adjustments and replacement of components Wheels and tyres: Inspection, servicing, replacements and creep indicators SELF SUSTAINING SAILPLANE AND MOTOR GLIDERS (SS or MG) (In addition to Airframe General) Piston Engines General Routine servicing; oil and filter changes, inspections Reduction gear/ belt system; Inspect, remove and install belts and adjust Crankshaft/drive flange; Inspect, check crankshaft run-out Tappets; Inspect, check and adjust clearance Check and record compression.
