INSTALLATION INSTRUCTIONS FOR PART NUMBER 182

Glare Shield Trimming

3. Make a paper pattern from the fiberglass glare shield.  Place this on top of the aircraft instrument panel and use it as a template for locating defroster slots, the windshield center post, etc.  Place it on the top of the fiberglass glare shield and cut holes as appropriate.

4. The recommended method for trimming the fiberglass glare shield is to use an air die grinder with a thin fiberglass abrasive cutting disc.  Mark the cutting line with a grease pencil.  For round cuts use a standard drill bit or Unibit

Installation

DO NOT DISTURB ANY STRUCTURAL PARTS OR ANY PERMANENTLY MOUNTED ITEMS ON TOP OF THE INSTRUMENT PANEL.

5. The optimal way to attach the glareshield is to use a self-tapping sheet metal screw (PK) to hold the glareshield in place.  One screw on each side where the glare shield rests on the panel should be sufficient.  As an alternate, you may use Rivnuts or equivalent.  In all cases you must be careful not to damage any structure or instruments.  The recommended screw placement is shown in Figure 3.

6. Reinstall any items that were temporarily removed from the top of the instrument panel.
